FUNCTIONAL
LIMITATIONS
The ProBar best produces accurate and repeatable flow measurement
under the following conditions:
• The maximum differential pressure, as printed on the tag
attached to the ProBar, is not exceeded.
• The ProBar is not used for two-phase flow or for steam service
below saturation temperature.
Install the ProBar in the correct location within the piping branch to
prevent measurement inaccuracies caused by flow disturbances.
ProBar installation allows for a maximum misalignment of 3 degrees,
as illustrated in Figure 2-2. Misalignment beyond 3 degrees will cause
errors in flow measurement.

Use Table 2-1 to determine the proper ProBar straight run requirements.
NOTES
For gas service, multiply values from Table 2-1 by 1.5.
If longer lengths of straight run are available, position the ProBar where
80% of the run is upstream of the ProBar and 20% is downstream.
Information contained in this manual applies to circular pipes only.
Consult the factory for instructions regarding ProBar use in square or
rectangular ducts.
Straightening vanes may be used to reduce the required straight run
length and will improve performance.

Installation Location and Orientation
ENVIRONMENTAL
CONSIDERATIONS
Location of the ProBar in pulsating flow will cause a noisy signal.
Vibration can also distort the output signal and compromise the
structural limits of the flowmeter. Mount the ProBar in a secure
run of pipe as far as possible from pulsation sources such as check
valves, reciprocating compressors or pumps, and control valves. Mount
the transmitter to minimize ambient temperature changes. Section 15:
Specifications and Reference Data lists the temperature operating
limits. Mount the transmitter to avoid vibration and mechanical shock;
mounting will also avoid external contact with corrosive materials. See
Section 8: ProBar Electronics Functions for environmental
considerations.
ProBar Orientation
Proper venting or draining must be considered when selecting a
ProBar location.
For liquid service, mount the side drain/vent valve upward; this allows
gases to vent. For gas service, mount the drain/vent valve down to allow
any accumulated liquid to drain. In steam service, fill lines with water
to prevent contact of the live steam with the electronics; condensate
chambers are not needed because the volumetric displacement of the
electronics is negligible.
ProBar instrument head connections differ on horizontal and vertical
pipes. Refer to the specification head code number to confirm the
proper pipe orientation for your ProBar.
Horizontal Pipe:
Liquid or Steam Application
Due to the possibility of air getting trapped in the probe, the ProBar
should be located per the drawing below. The area between 0° and
50° (50° angle) should not be used unless full bleeding of air from the
probe is possible. Figure 2-3 illustrates the recommended location
of the flowmeter.

The ProBar should be located on the upper half of the pipe, at least 30°
above the horizontal line. Figure 2-4 illustrates the recommended
location of the flowmeter.

The ProBar can be installed in any position around the circumference of
the pipe, provided the vents are positioned properly for bleeding or
venting. Vertical pipe installations require more frequent bleeding or
venting depending on the location. Figure 2-5 illustrates the
recommended location of the flowmeter.

Process Connections
(Remote Mounted
ProBar only)
The ProBar process connections on the electronics flange are ¼–18 NPT.
Flange adapter unions with ½–14 NPT connections are supplied as standard
with the remote mounted ProBar. The threads are Class 2; use your plantapproved lubricant or sealant when making the process connections. The
process connections on the electronics flange are on 21/8-inch (54 mm) centers
to allow direct mounting to a three-valve or five-valve manifold. Rotate one
or both of the flange adapters to attain connection centers of 2 inches (51
mm), 21/8 inches (54 mm), or 2¼ inches (57 mm).
Install and tighten all four flange bolts before applying pressure, or
process leakage will result. When properly installed, the flange bolts
will protrude through the top of the module housing. Do not attempt to
loosen or remove the flange bolts while the ProBar is in service.
Perform the following procedure to install adapters to a
coplanar flange:
1. Remove the flange bolts.
2. Leaving the flange in place, move the adapters into
position with the o-ring installed.
3. Clamp the adapters and the coplanar flange to the
transmitter module using the larger of the bolts supplied.
4. Tighten the bolts. Refer to Mounting Bolts on page 2-8 for
torque specifications.
Failure to install proper flange adapter O-rings can cause process leaks, which can
result in death or serious injury.
The flange adapters require a unique O-ring, as shown below.
Flange Adapter
O-ring
Unique O-ring Grooves
When compressed, Teflon® O-rings tend to cold flow, which aids in their
sealing capabilities. Whenever you remove flanges or adapters, visually
inspect the Teflon O-rings. Replace them if there are any signs of
damage, such as nicks or cuts. If they are undamaged, you may reuse
them. If the you replace the O-rings, retorque the flange bolts after
installation to compensate for cold flow. Refer to the process sensor body
reassembly procedure in Section 15: Troubleshooting.

ProBar Flowmeter
Mounting Bolts
The following guidelines have been established to ensure a tight flange,
adapter, or manifold seal. The ProBar is shipped with the Coplanar
flange installed with four 1.75-inch flange bolts. The following bolts also
are supplied to facilitate other mounting configurations:
Bolt Installation
Only use bolts supplied with the ProBar or sold by Rosemount
Inc. as spare parts for the ProBar. Use the following bolt
installation procedure:
1. Finger-tighten the bolts.
2. Torque the bolts to the initial torque value using a cross-pattern
(see Table 2-2 for torque values).
3. Torque the bolts to the final torque value using the
same cross-pattern.

STEP 1:
DETERMINE THE PROPER
PROBAR ORIENTATION
Orientation of the ProBar depends upon two factors: the orientation of
the pipe that will receive the flowmeter, and the service that uses the
pipe. The following sections provide illustrations of the possible pipe
orientations and services. After determining the flowmeter orientation,
proceed with Step 2 on page 3-5.
Liquid Service in a

STEP 2:
DRILL THE HOLE
IN THE PIPE
Follow the steps below to drill the hole in the pipe.
1. Depressurize and drain the pipe.
2. Select the location for the hole you are about to drill.
Select a location anywhere around the circumference
of the pipe for vertical pipes.
For horizontal pipes, the hole location depends upon
the service for which the ProBar is to be used:
• Liquid service: drill the hole along the bottom of the pipe
• Gas service: drill the hole along the top of the pipe
• Steam service: drill the hole along the bottom of the pipe
3. Determine the diameter of the hole to be drilled.
Use the chart in Figure 3-7.
4. After the hole is drilled, deburr the hole on the inside of the pipe.
Drill a Hole for
Opposite-Side Support
A second hole must be drilled for the opposite-side support weld
coupling if opposite-side support is supplied. This hole must be the
same diameter as the first hole; place it directly opposite the
first hole so that the sensor can pass completely through the pipe.
Use the following steps to find the location for the second hole:
1. Wrap a piece of soft wire or string around the pipe to
measure the pipe’s circumference.
2. Remove the wire or string and measure half of the
circumference length.
3. Re-wrap the half-length around the pipe from the
center of the first hole.
4. Mark the center of what will become the second hole,
as shown in Figure 3-7.
Note: Drill the hole 180 degrees from the first hole
for opposite-side support models.

DETERMINE THE PROPER
ORIENTATION
OF THE PROBAR
The orientation of the ProBar depends upon two factors: the orientation
of the pipe that will receive the flowmeter, and the service that uses the
pipe. The following sections provide illustrations of the possible pipe
orientations and services. After determining the ProBar’s orientation,
proceed with step 2 on page 6-4.

Throughout the remote mounting process:
• Use only valves and fittings rated for the service pipeline design
pressure and temperature as specified in Section 16:
Specifications and Reference Data.
• Use a pipe thread sealant compound that is rated for use at the
service temperature and pressure for all valves and fittings.
• Verify that all connections are tight and that all instrument
valves are fully closed.
• Verify that the sensor probe is properly oriented for the intended
type of service: liquid, gas or steam (see Figures 8-1, 8-2, and 8-3).

ProBar Remote Mounting
Impulse Piping
A remote mounted electronics is connected to the sensor by means of
impulse piping. Temperatures in excess of 250 °F at the electronics
will damage electronics components; impulse piping allows service
flow temperatures to decrease to a point where the electronics is no
longer vulnerable.
Each service uses a different impulse piping arrangement to maintain a
single phase of fluid in the piping and ProBar electronics. For example,
liquid applications must maintain a liquid state and allow any air or
gas formation to travel up and away from the ProBar electronics, and
gas applications must maintain a gaseous state and allow the formation
of liquids to drain down and away from the ProBar electronics.
The piping used to connect the sensor probe and electronics must be
rated for continuous operation at the pipeline-designed pressure and
temperature. A minimum of one-half inch (½-in., 12mm) O.D. stainless
steel tubing with a wall thickness of at least 0.035" is recommended.
Threaded pipe fittings are not recommended because they create voids
where air can become entrapped and have more possibilities for
leakage.
The following restrictions and recommendations apply to impulse
piping location.
1. Impulse piping that runs horizontally must slope at least one inch
per foot (83mm/m).
• It must slope downwards (toward the ProBar electronics) for
liquid and steam applications.
• It must slope up (away from the ProBar electronics) for gas
applications.
2. For applications where the pipeline temperature is below 250 °F
(121 °C), the impulse piping should be as short as possible to
minimize flow temperature changes. Insulation may be required.
3. For applications where pipeline temperature is above 250 °F
(121 °C), the impulse piping should have a minimum length of
one foot (0.3048 m) for every 100 °F (38 °C) over 250 °F (121 °C),
which is the maximum operating ProBar electronics temperature.
Impulse piping must be uninsulated to reduce fluid temperature.
All threaded connections should be checked after the system
comes up to temperature, because connections may be loosened by
the expansion and contraction caused by temperature changes.
4. Outdoor installations for liquid, saturated gas, or steam service
may require insulation and heat tracing to prevent freezing.
5. For installations where the ProBar electronics are more than
six feet (1.8m) from the sensor probe, the high and low impulse
piping must be run together to maintain equal temperature.
They must be supported to prevent sagging and vibration.
6. Run impulse piping in protected areas or against walls or ceilings.
If the impulse piping is run across the floor, ensure that it is
protected with coverings or kick plates. Do not locate the impulse
piping near high temperature piping or equipment.
7. Use an appropriate pipe sealing compound rated for the service
temperature on all threaded connections. When making threaded
connections between stainless steel fittings, Loctite PST Sealant
is recommended.

ProBar Flowmeter
EQUIPMENT REQUIRED
TO REMOTE MOUNT THE
PROBAR ELECTRONICS
Proper installation of the ProBar electronics requires the following
tools and equipment.
Tools Required
Tools required include the following:
1. Open end or combination wrenches (spanners) to fit the pipe
fittings and bolts: 9/16-in., 5/8-in., 7/8-in.
2. Adjustable wrench: 15-in. (1½-in. jaw).
3. Nut driver: 3/8-in. for vent/drain valves (or 3/8-in. wrench).
4. Phillip’s screwdriver: #1.
5. Standard screwdrivers: ¼-in., and 1/8-in. wide.
6. Pipe wrench: 14-in.
7. Wire cutters/strippers.
Supplies Required
Supplies required include the following:
1. ½-in. Tubing (recommended) or ½-in. pipe to hook up the ProBar
electronics to the sensor probe. The length required depends upon
the distance between the electronics and the sensor.
2. Fittings including, but not limited to:
a. Two tube or pipe tees (for steam or high temperature liquid)
b. Six tube/pipe fittings (for tube)
3. Pipe compound or teflon tape (where local piping codes allow).
INSTRUMENT MANIFOLDS
An instrument manifold is recommended for all installations. A
manifold allows an operator to equalize the pressures prior to the zero
calibration of the ProBar electronics as well as to isolate the electronics
from the rest of the system without disconnecting the impulse piping.
Although a 3-valve manifold can be used, a 5-valve manifold is
recommended. Figure 8-4 identifies the valves on a 5-valve and a
3-valve manifold.
5-valve manifolds provide a positive method of indicating a partially
closed or faulty equalizer valve. A closed for faulty equalizer valve will
block the DP signal and create errors that may not be detectable
otherwise. Figure 8-4 shows the DP manifold assembly and identifies
the valves on both types of manifolds, and Table 8-1 provides a
description of the valves. The labels for each valve will be used to
identify the proper valve in the procedures to follow.
NOTE
Some recently-designed instrument manifolds have a single valve
actuator, but cannot perform all of the functions available on standard
5-valve units. Check with the manufacturer to verify the functions that
a particular manifold can perform. In place of a manifold, individual
valves may be arranged so as to provide the necessary isolation and
equalization functions.
NOTE
The ProBar should be shipped with the instrument manifold already
bolted to the electronics.

For steam service (at any temperature) or liquid service at
temperatures above 250 °F (121 °C), the ProBar electronics
must be installed below the process piping.
NOTE
Steam (or hot water) must not enter the electronics. Fill the system of
impulse piping and ProBar electronics with cool water before
pressurizing the system.
Horizontal Pipes
For horizontal steam process piping, the ProBar flow sensor is mounted
through the bottom half of the piping, as shown in Figure 8-9. Route
impulse piping down to the ProBar electronics. Fill the system with cool
water through the two tee fittings.

SAFETY MESSAGES
ProBar Electronics Functions
Procedures and instructions in this section may require special
precautions to ensure the safety of the personnel performing the
operations. Information that raises potential safety issues is indicated
by a warning symbol ( ). Refer to the following safety messages before
performing an operation preceded by this symbol.
Explosions could result in death or serious injury:
• Do not remove the transmitter cover in explosive atmospheres when the circuit is alive.
• Before connecting a HART-based communicator in an explosive atmosphere, make
sure the instruments in the loop are installed in accordance with intrinsically safe or
non-incendive field wiring practices.
• Verify that the operating atmosphere of the transmitter is consistent with the
appropriate hazardous locations certifications.
• Both transmitter covers must be fully engaged to meet explosion-proof requirements.
• The unused conduit opening on the electronics housing must be plugged and sealed to
meet explosion-proof requirements.
Failure to follow these installation guidelines could result in death or serious injury:
• Make sure only qualified personnel perform the installation.
For intrinsically safe installations, wiring connections must be made in accordance
with ANSI/ISA-RP12.6, and Rosemount drawings 03031-1019 or 03031-1024.
For ALL installations, wiring connections must be made in accordance with local or
national installation codes such as the NEC NFPA 70.
This section contains information on commissioning and operating
ProBar flowmeters. Tasks that should be performed on the bench prior
to installation (setting flowmeter jumpers) and software functions are
explained in this section.
For your convenience, HART communicator fast key sequences are
listed for each software function. If you are unfamiliar with the
communicator or how to follow fast key sequences, please refer to
Appendix A: HART Communicator for communicator operations.

ProBar Flowmeter
COMMISSIONING
THE FLOWMETER
ON THE BENCH
Commissioning consists of testing the flowmeter, testing the loop, and
verifying flowmeter configuration data. You may commission ProBar
flowmeters either before or after installation. Commissioning the
flowmeter on the bench before installation ensures that all flowmeter
components are in good working order and acquaints you with the
operation of the device.
To avoid exposing the flowmeter electronics to the plant environment after
installation, set the failure mode and flowmeter security jumpers during
the commissioning stage on the bench.
FAILURE MODE ALARM
As part of normal operation, the ProBar continuously monitors its own operation.
This automatic diagnostic routine is a timed series of checks repeated
continuously. If the diagnostic routine detects a failure, the flowmeter drives its
output either below or above specific values depending on the position of the
failure mode jumper.
• For 4–20 mA flowmeters factory-configured for standard operation, the
flowmeter drives its output either below 3.75 mA or above 21.75 mA.
• For 4–20 mA flowmeters factory-configured for NAMUR-compliant
operation, the flowmeter drives its output either below 3.6 mA or above
22.5 mA.
The failure mode alarm jumper is located on the front of the electronics board
inside of the electronics housing cover. The position of this jumper determines
whether the output is driven high or low when a failure is detected (see Figure
9-1 on page 9-4). If the alarm jumper is not installed the flowmeter will operate
normally, and the default alarm condition will be high.
NOTE
The failure mode alarm jumper pins occupy one row of a ten-pin socket that also
is used to attach the optional LCD meter. In order to function appropriately, the
jumper must be positioned correctly, as shown in Figure 9-1 on page 9-4.

Saturation Output Values
TABLE 9-1. Analog Output:
Standard Alarm Values vs.
Saturation Values.
TABLE 9-2. Analog Output:
NAMUR-Compliant Alarm Values
vs. Saturation Values.
9-2
The failure mode alarm output levels differ from the output values that occur
when applied pressure is outside the range points. When pressure is outside the
range points, the analog output continues to track the input pressure until
reaching the saturation value listed below; the output does not exceed the listed
saturation value regardless of the applied pressure. For example, with standard
alarm and saturation levels and pressures outside the 4–20 range points, the
output saturates at 3.9 mA or 20.8 mA. When the flowmeter diagnostics detect a
failure, the analog output is set to a specific alarm value that differs from the
saturation value to allow for proper troubleshooting.

NOTE
You can alter the actual flowmeter mA output values from the values
listed above by performing an analog output trim (see page 9-20).
NOTE
When a flowmeter is in an alarm condition, the hand-held HART
communicator indicates the analog output the flowmeter would drive if
the alarm condition did not exist.
Alarm and Saturation
Values for Flowmeters
Set to Burst Mode
Saturation and alarm conditions operate differently when a flowmeter is
set to burst mode operation:
Alarm Condition (Hi or Lo):
1. Analog output switches to alarm level (see Table 9-1).
2. Primary variable (flow pressure) is burst with a status bit set.
3. Percent of range follows primary variable (flow pressure).
4. Secondary variable (DP pressure) and Tertiary variable
(temperature) are burst with a status bit set.
(Note that during alarm conditions, the burst primary variable,
secondary variable, or percent of range, or temperature may not be valid
depending on the error type – refer to the HART protocol for details.)
Saturation:
1. Analog output switches to saturation level (see Table 9-1).
2. Primary variable (flow pressure) is burst normally.
3. Secondary variable (D.P. pressure) and tertiary variable
(temperature) are burst normally.
Alarm Level Verification
Flowmeters with electronics board revision 5.3 or later (shrouded design) have
increased functionality that allows verification testing of alarm current levels.
If you repair or replace the flowmeter electronics board, sensor module or LCD
meter, verify the flowmeter alarm level before you return the flowmeter to
service. This feature is also useful in testing the reaction of your control system
to a flowmeter in an alarm state. To verify the flowmeter alarm levels, perform
a loop test (see Loop Test on page 9-14).
9-3
ProBar Flowmeter
FLOWMETER SECURITY
You can prevent changes to the flowmeter configuration data with the write
protection jumper. Position the jumper on the flowmeter circuit board in the
“ON” position to prevent accidental or deliberate change of configuration data.
Figure 9-1 shows the jumper positions for 4–20 mA flowmeters. For flowmeters
with an optional LCD meter, see “LCD Meter” in Installation Options.
If the flowmeter write protection jumper is in the “ON” position, the
flowmeter will not accept any “writes” to its memory. Configuration
changes (such as digital trim and reranging) cannot take place
when the flowmeter security is on. To reposition the jumper, perform
the following procedure.
1. If the flowmeter is installed, secure the loop, and remove power.
2. Remove the housing cover opposite the field terminal side. Do not
remove the flowmeter covers in explosive atmospheres when the
circuit is alive.
3. Reposition the jumper. See Figure 9-1 for the ON and OFF jumper
positions. Previous circuit boards carried a two-pin or three-pin
jumper assembly on the connector side of the board (see Figure 9-1).
To activate security using a two-pin version, install the jumper. To
activate security with the three-pin assembly, move the jumper to
the ON pin position.
4. Reattach the flowmeter cover. Flowmeter covers must be fully
engaged to meet explosion-proof requirements.
NOTE
If the security jumper is not installed, the flowmeter will continue to
operate in the security OFF configuration.

COMMISSIONING
THE PROBAR WITH
A HART-BASED
COMMUNICATOR
Before placing the ProBar into operation, you should commission the
instrument using a HART-based communicator.
To commission on the bench, connect the flowmeter and the communicator as
shown in Figure 9-2. Make sure the instruments in the loop are installed in
accordance with intrinsically safe or nonincendive field wiring practices
before connecting a communicator in an explosive atmosphere. Connect the
communicator leads at any termination point in the signal loop. It is most
convenient to connect them to the terminals labeled “COMM” on the
terminal block. Connecting across the “TEST” terminals will prevent
successful communication.
For 4–20 mA flowmeters, you will need a power supply capable of providing
10.5 to 55 V dc at the flowmeter, and a meter to measure output current. To
enable communication, a resistance of at least 250 ohms must be present
between the communicator loop connection and the power supply. Do not use
inductive-based transient protectors with the ProBar.
Setting the
Loop to Manual
Whenever you are preparing to send or request data that would disrupt
the loop or change the output of the flowmeter, you must set your process
application loop to manual. The HART Communicator Model 275 will
prompt you to set the loop to manual when necessary. Keep in mind that
acknowledging this prompt does not set the loop to manual. The
prompt is only a reminder; you have to set the loop to manual yourself, as
a separate operation.
Wiring Diagrams
(Bench Hook-up)
Connect the bench equipment as shown in Figure 9-2 and turn on the
HART-based communicator by pressing the ON/OFF key. The
communicator will search for a HART-compatible device and will
indicate when the connection is made. If the communicator fails to
connect, it will indicate that no device was found. If this occurs, refer to
Section 15: Troubleshooting.

CONFIGURATION DATA
HART Comm.
1, 5
NOTE
Information and procedures in this section that make use of HART
Communicator fast key sequences assume that the flowmeter and
communicator are connected, powered, and operating correctly.
If you are not familiar with the HART Communicator or fast-key
sequences, refer to Appendix A: HART Communicator.
Before you place the flowmeter into operation, it is recommended that you
review the flowmeter configuration data that was set at the factory. You
should review the following configuration data: Flowmeter Model, Type,
Tag, Range, Date, Descriptor, Message, Minimum and Maximum Sensor
Limits, Minimum Span, Units, 4 and 20 mA points, Output (linear or
square root), Damping, Alarm Setting (high, low), Security Setting (on,
off), Local Keys (enabled, disabled), Integral Meter, Sensor Fill, Isolator
Material, Flange (type, material), O-Ring Material, Drain/Vent, Remote
Seal (type, fill fluid, isolator material, number), Flowmeter S/N, Address,
and Sensor S/N.
CHECK OUTPUT
Before performing other flowmeter on-line operations, review the digital
output parameters to ensure that the flowmeter is operating properly and
is configured to the appropriate process variables.
Process Variables
The process variables for the ProBar provide the flowmeter output, and
are continuously updated. The process variable menu displays the
following process variables:
HART Comm.
1, 2
• Flow Pressure
• Percent of Range
• Analog Output
• DP Pressure
• Sensor Temperature
The flow pressure reading in both Engineering Units and Percent of
Range will continue to track with pressures outside of the defined range
from the lower to the upper range limit of the sensor module.(1)
Sensor Temperature
HART Comm.
1, 1, 5
The ProBar contains a temperature sensor just above its pressure sensor
in the sensor module. When reading this temperature, keep in mind that
this is not a process temperature reading.
(1) Previous versions of the software will track with pressure up to 105% of span, and remain
there as pressure increases.

Activate the flowmeter square root output option to make the analog
output proportional to flow. To avoid the extremely high gain that results
as the input approaches zero, the ProBar automatically switches to a
linear output in order to ensure a more stable output near zero. The
transition from linear to square root output is smooth, with no step change
or discontinuity in output (see Figure 9-4).
The transition from linear to square root is not adjustable. It occurs at
0.8% of ranged pressure input. In earlier software, the transition point
occurred at 4% of ranged pressure input, or 20% of full scale flow output.
From 0 percent to 0.6 percent of the ranged pressure input, the slope of
the curve is unity (y = x). This allows accurate calibration near zero.
Greater slopes would cause large changes in output for small changes at
input. From 0.6 percent to 0.8 percent, the slope of the curve equals 42 (y =
42x) to achieve continuous transition from linear to square root at the
transition point.

ProBar Flowmeter
Rerange
The Range Values command sets the 4 and 20 mA points (lower and upper
range values). Setting the range values to the limits of expected readings
maximizes flowmeter performance; the flowmeter is most accurate when
operated within the expected pressure ranges for your application. In practice,
you may reset the flowmeter range values as often as necessary to reflect
changing process conditions.
NOTE
Regardless of the range points, the ProBar will measure and report all readings
within the digital limits of the sensor. For example, if the 4 and 20 mA points
are set to 0 and 10 inH20, and the flowmeter detects a pressure of 25 inH20, it
digitally outputs the 25 in H20 reading and a 250% percent of span reading.
However, there may be up to ±5.0% error associated with output outside of the
range points.
You may use one of three methods to rerange the flowmeter. Each method is
unique; examine all three closely before deciding which method to use.
When reranging a calibrated ProBar, the new DP must be calculated at the
factory during calibration. The ProBar is a flowmeter calibrated at reference
conditions and has been ranged according to the conditions given at the time of
order placement. If the density, pressure, temperature, fluid, or pipe ID has
changed, please consult publication number DS-4012 ProBar Flow Handbook
for equations prior to reranging the flowmeter.
The ProBar information specific to the flowmeter can be found on the flow
calibration report (as shown below) or on the ProBar flowmeter tag.
The calculation used to rerange the ProBar output is as follows:
New DP Range
newQmax 2
=  -------------------------- 3 Old DP Range
oldQmax
For instance, if the ProBar is currently setup as follows:
ProBar Information
Model: ProBar Flanged
Serial#: 222222.2
Max Flow @ 20 mA: 1600 GPM
Max DP @ 20 mA: 153 inH2O
And then you want to rerange 20 mA to 2000 gpm, the
calculation is as follows:
New DP Range
2000
=  ------------
 1600
2
3 153 inH2O = 239 inH2O
The ProBar can now be reranged to the following new settings:
4 mA = 0 in H2O
20 mA = 239 inH20
9-10
ProBar Electronics Functions
Rerange with a
Communicator Only
HART Comm.
1, 2, 3, 1, 1
Reranging using only the communicator is the easiest and most popular
way to rerange the flowmeter. This method changes the values of the
analog 4 and 20 mA points independently without a pressure input.
NOTE
Changing the lower or upper range point results in similar
changes to the span.
To rerange using only the communicator enter the fast-key sequence
above, select 1 Keypad input, and follow the on-line instructions.
Or enter the values directly from the HOME screen.
NOTE
If the flowmeter security jumper is in the “ON” position, you will not be
able to make adjustments to the zero and span. Refer to Figure 9-1 on
page 9-4 for the appropriate placement of the flowmeter security jumper.
Rerange with a
Pressure Input Source
and a Communicator
HART Comm.
1, 2, 3, 1, 2
Reranging using the communicator and a pressure source or process
pressure is a way of reranging the flowmeter when specific 4 and 20 mA
points are not known. This method changes the values of the analog 4 and
20 mA points.
NOTE
When you set the 4 mA point the span is maintained; when you set
the 20 mA point the span changes. If you set the lower range point
to a value that causes the upper range point to exceed the sensor
limit, the upper range point is automatically set to the sensor limit,
and the span is adjusted accordingly.
To rerange using the communicator and a pressure source or process
pressure enter the fast-key sequence above, select 2 Apply values, and
follow the on-line instructions.
NOTE
If the flowmeter security jumper is in the “ON” position, you will not be
able to make adjustments to the zero and span. Refer to Figure 9-1 on
page 9-4 for the appropriate placement of the flowmeter security jumper.

ProBar Flowmeter
Rerange with a Pressure Input
Source and the Local Zero and
Span Buttons
Reranging using the local zero and span adjustments (see Figure 9-5 on page
9-13), and a pressure source is a way of reranging the flowmeter when specific 4
and 20 mA points are not known and a communicator is not available.
NOTE
When you set the 4 mA point the span is maintained; when you set the 20
mA point the span changes. If you set the lower range point to a value that
causes the upper range point to exceed the sensor limit, the upper range
point is automatically set to the sensor limit, and the span is adjusted
accordingly.
To rerange the flowmeter using the span and zero buttons, perform the
following procedure.
1. Loosen the screw holding the certifications label on top of the
flowmeter housing, and rotate the label to expose the zero and span
buttons (see Figure 9-5 on page 9-13).
2. Using a pressure source with an accuracy three to ten times the
desired calibrated accuracy, apply a pressure equivalent to the lower
range value to the high side of the flowmeter.
3. To set the 4 mA point, press and hold the zero button for at least two
seconds, then verify that the output is 4 mA. If a meter is installed,
it will display ZERO PASS.
NOTE
The zero and span adjustments on previous versions of the flowmeter are
screws instead of buttons. To activate the zero or span adjustment loosen
the screw until it pops up.
4. Apply a pressure equivalent to the upper range value to the high
side of the flowmeter.
5. To set the 20 mA point, press and hold the span button for at least two
seconds, then verify that the output is 20 mA. If a meter is installed,
it will display SPAN PASS.
NOTE
If the flowmeter security jumper is in the “ON” position, or if the local zero
and span adjustments are disabled through the software, you will not be
able to make adjustments to the zero and span using the local buttons.
Refer to Figure 9-1 on page 9-4 for the proper placement of the flowmeter
security jumper. Or refer to Local Span and Zero Control on page 9-14
for instructions on how to enable the span and zero buttons.

The PV damp command changes the response time of the flowmeter to
smooth variations in output readings caused by rapid changes in input.
Determine the appropriate damping setting based on the necessary

NOTE
Disabling the local keys does not disable all flowmeter configuration
changes. With the local keys disabled, you can still make changes to the
flowmeter configuration using a HART Communicator.
DIAGNOSTICS
AND SERVICE
The diagnostics and service functions listed here are primarily for use
after you install the flowmeter in the field. The transmitter test feature is
designed to verify that the flowmeter is operating properly, and can be
performed either on the bench or in the field. The loop test feature is
designed to verify proper loop wiring and flowmeter output, and should
only be performed after you install the flowmeter.
Transmitter Test
The transmitter test command initiates a more extensive diagnostics
routine than that performed continuously by the flowmeter. The flowmeter
test routine can quickly identify potential electronics problems. If the
transmitter test detects a problem, messages to indicate the source of the
problem are displayed on the communicator screen.
HART Comm.
1, 2, 1, 1
Loop Test
HART Comm.
1, 2, 2
The Loop Test command verifies the output of the flowmeter, the integrity
of the loop, and the operations of any recorders or similar devices installed
in the loop. To initiate a loop test, perform the following procedure:
1. Connect a reference meter to the flowmeter. To do so, either connect the
meter to the test terminals on the flowmeter terminal block, or shunt
the power to the flowmeter through the meter at some point in the loop.
2. From the HOME screen, Select 1 Device Setup, 2 Diagnostics and
Service, 2 Loop Test, to prepare to perform a loop test.
3. Select “OK” after you set the control loop to manual (see Setting
the Loop to Manual on page 9-5).
The communicator displays the loop test menu.
4. Select a discrete milliamp level for the flowmeter to output. At the
“Choose analog output” prompt, select 1 4mA, 2 20mA, or select
3 other to manually input a value.
If you are performing a loop test to verify the output of a flowmeter,
enter a value between 4 and 20 mA. If you are performing a loop test
to verify the flowmeter alarm levels, enter the milliamp value at
which the flowmeter should enter an alarm state (see Tables 9-1 and
9-2 on page 9-2).
5. Check the electrical current meter installed in the test loop to verify
that it reads the value you commanded the flowmeter to output. If the
readings match, the flowmeter and the loop are configured and
functioning properly. If the readings do not match, there may be a
fault in the wiring, the flowmeter may require an output trim, or the
electrical current meter may be malfunctioning.
After completing the test procedure, the display returns to the loop test screen
and allows you to choose another output value or to exit loop testing.

ProBar Electronics Functions
CALIBRATION
Calibrating a smart flowmeter is different from calibrating an analog
flowmeter. The one-step calibration process of an analog flowmeter is done
in three steps with a smart flowmeter:
• Rerange – sets the 4 and 20 mA points at the desired pressures;
• Sensor Trim – Adjusts the position of the factory characterization
curve to optimize the flowmeter performance over a specified
pressure range or to adjust for mounting effects;
• Analog Output Trim – Adjusts the analog output to match the plant
standard or the control loop.
To understand the calibration of a ProBar smart flowmeter, it is necessary to
understand that smart flowmeters operate differently than analog
flowmeters. A smart flowmeter uses a microprocessor that contains
information about the sensor’s specific characteristics in response to
pressure and temperature inputs; each sensor varies slightly. A smart
flowmeter compensates for these sensor variations. The process of
generating the sensor performance profile is called factory characterization,
and it enables a smart flowmeter to maintain higher performance
specifications than analog flowmeters.
It is also important to understand the difference between the trim and the
rerange functions of smart flowmeters. Reranging sets the flowmeter
analog output to the selected upper and lower range points, and can be
done with or without an applied pressure. Reranging does not change the
factory characterization curve stored in the microprocessor. In contrast,
sensor trimming requires an accurate pressure input, and adds additional
compensation that adjusts the position of the factory characterization
curve.
NOTE
Sensor trimming adjusts the position of the factory characterization curve.
It is possible to degrade the performance of the flowmeter if the sensor
trim is done improperly or with equipment that does not meet the
accuracy requirements. If you have questions about the calibration
process or the trim procedure, contact your local Dieterich Standard
representative or contact Dieterich Standard Inc. at 1 (303) 530-9600.

ProBar Flowmeter
Calibration Overview
Complete calibration of the ProBar flowmeter involves the following tasks:
Configure the Analog Output Parameters
• Set Process Variable Units (page 9-8)
• Set Output Type (page 9-10)
• Rerange (page 9-10)
• Set Damping (page 9-13)
Calibrate the Sensor
• Full Trim, ProBar UC or ProBar field revision 3 or later (page 9-19)
NOTE
Do not perform a full trim for ProBar flowmeters with a device-type
ProBar and a field revision earlier than field revision 3.
• Zero Trim (page 9-19)
Calibrate the 4–20 mA Output
• 4–20 mA Output Trim (page 9-20) or
• 4–20 mA Output Trim Using Other Scale (page 9-20)
Figure 9-6 illustrates the ProBar flowmeter data flow. This data flow can
be summarized in four major steps:
1. A change in pressure is measured by a change in the sensor output
(Sensor Signal).
2. The sensor signal is converted to a digital format that can be
understood by the microprocessor (Analog-to-Digital Signal
Conversion).
3. Corrections are performed in the microprocessor to obtain a digital
representation of the process input (Digital PV).
4. The Digital PV is converted to an analog value
(Digital-to-Analog Signal Conversion).
Figure 9-6 also identifies the approximate flowmeter location for each
calibration task. Note that the data flows from left to right, and a parameter
change affects all values to the right of the changed parameter.
Not all calibration procedures should be performed for each ProBar
flowmeter. In addition, some procedures are appropriate for bench
calibration, but should not be performed during field calibration. Figure
9-6 identifies the recommended calibration procedures for each type of
ProBar flowmeter for both bench and field calibration.

To decide which trim procedure to use, you must first determine whether
the analog-to-digital section or the digital-to-analog section of the
flowmeter electronics is in need of calibration. To do so, refer to Figure 9-6
and perform the following procedure:
1. Connect a pressure source, a HART communicator, and a digital
readout device to the flowmeter.
2. Establish communication between the flowmeter
and the communicator.
3. Apply pressure equal to the upper range point pressure
(100 in H20, for example).
4. Compare the applied pressure to the Secondary Variable (Press) line
on the Communicator Process Variables Menu. If the Press reading
on the communicator does not match the applied pressure, and you
are confident that your test equipment is accurate, perform a sensor
trim.
5. Compare the Analog Output (AO) line on the communicator on-line
menu to the digital readout device. If the AO reading on the
communicator does not match the digital readout device, and you
are confident that your test equipment is accurate, perform an
output trim.
9-17
ProBar Flowmeter
You can trim the sensor using either the full trim or the zero trim
function. The trim functions vary in complexity, and their use is
application-dependent. Both trim functions alter the interpretation
of the input signal.
Sensor Trim
A zero trim is a single-point adjustment. It is useful for compensating for
mounting position effects, and is most effective when performed with the
flowmeter installed in its final mounting position. Since this correction
maintains the slope of the characterization curve, it should not be used in
place of a full trim over the full sensor range.
When performing a zero trim, ensure that the equalizing valve is open and
all wet legs are filled to the correct levels.
A full trim is a two-point sensor calibration where two end-point
pressures are applied, and all output is linearized between them. You
should always adjust the low trim value first to establish the correct
offset. Adjustment of the high trim value provides a slope correction to the
characterization curve based on the low trim value. The factoryestablished characterization curve is not changed by this procedure. The
trim values allow you to optimize performance over your specified
measuring range at the calibration temperature.
Zero Trim
HART Comm.
1, 2, 3, 3, 1
To calibrate the sensor with a HART Communicator using the zero trim
function, perform the following procedure.
1. Vent the flowmeter and attach a communicator to the measurement
loop.
2. From the communicator main menu select 1 Device setup,
2 Diagnostics and service, 3 Calibration, 3 Sensor trim, 1 Zero trim
to prepare to adjust the zero trim.
NOTE
The flowmeter must be within 3% of true zero (zero based) in order to
calibrate using the zero trim function.
3. Follow the commands provided by the communicator to complete the
adjustment of the zero trim.

NOTE
Do not perform a full trim for ProBar flowmeters with a device-type

To calibrate the sensor with a HART communicator using the full trim
function, perform the following procedure.
1. Assemble and power the entire calibration system including a
flowmeter, HART communicator, power supply, pressure input
source, and readout device (see Figure 9-7).
NOTE
Use a pressure input source that is at least three times more accurate
than the flowmeter, and allow the input pressure to stabilize for 10
seconds before entering any values.
2. From the communicator main menu select 1 Device setup,
2 Diagnostics and service, 3 Calibration, 3 Sensor trim, 2 Lower
sensor trim to prepare to adjust the lower trim point.
NOTE
Select pressure input values so that the low and high values are
equal to or outside the 4 and 20 mA points. Do not attempt to obtain
reverse output by reversing the high and low points. The flowmeter
allows approximately a 5% URL deviation from the characterized
curve established at the factory.
3. Follow the commands provided by the communicator to complete the
adjustment of the lower value.
4. Repeat the procedure for the upper value, replacing 2 Lower sensor
trim with 3 Upper sensor trim in Step 2.

lead to the positive terminal and the negative lead to the test
terminal in the flowmeter terminal compartment, or shunt the
flowmeter power through the reference meter at some point.
3. Select “OK” after connecting the reference meter.
4. Select “OK” at the “Setting fld dev output to 4 mA” prompt.
The flowmeter outputs 4.00 mA.
5. Record the actual value from the reference meter, and enter it at the
“Enter meter value” prompt.
The communicator prompts you to verify whether or not the output
value equals the value on the reference meter.
6. Select 1 Yes if the reference meter value equals the flowmeter output
value, or 2 No if it does not.
If you select 1 Yes, proceed to Step 7.
If you select 2 No, repeat Step 5.
7. Select “OK” at the “Setting fld dev output to 20 mA” prompt, and
repeat Steps 5 and 6 until the reference meter value equals the
flowmeter output value.
8. Select “OK” after you return the control loop to automatic control.

The Scaled D/A Trim command matches the 4 and 20 mA points to a userselectable reference scale other than 4 and 20 mA (1 to 5 volts if
measuring across a 250 ohm load, or 0 to 100 percent if measuring from a
DCS, for example). To perform a scaled D/A trim, connect an accurate
reference meter to the flowmeter and trim the output signal to scale as
outlined in the Output Trim procedure.
NOTE
Use a precision resistor for optimum accuracy. If you add a resistor to the
loop, ensure that the power supply is sufficient to power the flowmeter to a
20 mA output with the additional loop resistance.

The flowmeter receiving the cloned data must have the same or a newer
version of software than the original flowmeter.
9-21
ProBar Flowmeter
Burst Mode
HART Comm.
1, 4, 3, 3, 3
When configured for burst mode, the ProBar provides faster digital
communication from the flowmeter to the control system by eliminating
the time required for the control system to request information from the
flowmeter. Burst mode is compatible with use of the analog signal.
Because HART protocol features simultaneous digital and analog data
transmission, the analog value can drive other equipment in the loop
while the control system is receiving the digital information. Burst mode
applies only to the transmission of dynamic data (pressure and
temperature in engineering units, pressure in percent of range, and/or
analog output), and does not affect the way other flowmeter data is
accessed.
Access to information other than dynamic flowmeter data is obtained
through the normal poll/response method of HART communication. A
HART-based communicator or the control system may request any of the
information that is normally available while the flowmeter is in burst
mode. Between each message sent by the flowmeter, a short pause allows
the HART-based communicator or a control system to initiate a request.
The flowmeter will receive the request, process the response message, and
then continue “bursting” the data approximately three times per second.
Multidrop
Communication
Multidropping transmitters refers to the connection of several transmitters
to a single communications transmission line. Communication between the
host and the flowmeters takes place digitally with the analog output of the
flowmeters deactivated. With the HART smart communications protocol, up
to 15 transmitters can be connected on a single twisted pair of wires or over
leased phone lines. This feature can greatly reduce wiring costs.
The application of a multidrop installation requires consideration of the
update rate necessary from each transmitter, the combination of
transmitter models, and the length of the transmission line. Multidrop
installations are not recommended where intrinsic safety is a
requirement. Communication with the transmitters can be accomplished
with commercially available Bell 202 modems and a host implementing
the HART protocol. Each transmitter is identified by a unique address (1–
15) and responds to the commands defined in the HART protocol. HARTbased communicators can test, configure, and format a multidropped
flowmeter the same way as a transmitter in a standard point-to-point
installation.
Figure 9-8 on page 9-23 shows a typical multidrop network. This figure is
not intended as an installation diagram. Contact Dieterich Standard
product support with specific requirements for multidrop applications.

The ProBar is set to address 0 at the factory, allowing it to operate in the
standard point-to-point manner with a 4–20 mA output signal. To activate
multidrop communication, the flowmeter address must be changed to a
number from 1 to 15. This change deactivates the 4–20 mA analog output,
sending it to 4 mA. It also disables the failure mode alarm signal, which is
controlled by the upscale/downscale jumper position. Failure signals in
multidropped flowmeters are communicated through HART messages.

Procedures and instructions in this section may require special
precautions to ensure the safety of the personnel performing the
operations. Information that raises potential safety issues is indicated
by a warning symbol ( ). Refer to the following safety messages before
performing an operation preceded by this symbol.
Explosions could result in death or serious injury:
• Do not remove the transmitter cover in explosive atmospheres when the circuit is alive.
• Before connecting a HART-based communicator in an explosive atmosphere, make
sure the instruments in the loop are installed in accordance with intrinsically safe or
non-incendive field wiring practices.
• Verify that the operating atmosphere of the transmitter is consistent with the
appropriate hazardous locations certifications.
• Both transmitter covers must be fully engaged to meet explosion-proof requirements.
• The unused conduit opening on the electronics housing must be plugged and sealed to
meet explosion-proof requirements.
Failure to follow these installation guidelines could result in death or serious injury:
• Make sure only qualified personnel perform the installation.
For intrinsically safe installations, wiring connections must be made in accordance
with ANSI/ISA-RP12.6, and Rosemount drawings 03031-1019 or 03031-1024.
For ALL installations, wiring connections must be made in accordance with local or
national installation codes such as the NEC NFPA 70.

Communication requires a minimum loop resistance of 250 ohms.
(1) For CSA approval, power supply must not exceed 42.4 V.
POWER SUPPLY

The dc power supply should provide power with less than 2 percent ripple.
The total resistance load is the sum of the resistance of the signal leads and
the load resistance of the controller, indicator, and related pieces. Note that
the resistance of intrinsic safety barriers, if used, must be included.
NOTE
A minimum loop resistance of 250 ohms is required to communicate with a
HART-based communicator. With 250 ohms of loop resistance, the ProBar
will require a minimum of 15.5 volts to output 20 mA. If a single power
supply is used to power more than one ProBar, the power supply used, and
circuitry common to the ProBars, should not have more than 20 ohms of
impedance at 1200Hz.

Field Wiring and Electrical Considerations
WIRING
To make connections, remove the housing cover on the side marked
FIELD TERMINALS. Do not remove the instrument covers in explosive
atmospheres when the circuit is alive. All power to the ProBar is
supplied over the signal wiring. Connect the lead that originates at the
positive side of the power supply to the terminal marked “+” and the
lead that originates at the negative side of the power supply to the
terminal marked “–.” Avoid contact with the leads and terminals.
Inductive-based transient protectors, including the Model 470, can
adversely affect the output of the ProBar. Do not use the Model 470
for transient protection with the ProBar. If transient protection is
desired, install the Transient Protection Terminal Block. Consult the
factory for instructions.
HAZARDOUS LOCATIONS
The ProBar has an explosion-proof housing and circuitry suitable for
intrinsically safe and non-incendive operation. Individual ProBar
models are clearly marked with a tag indicating the certifications they
carry. See Section 16: Specifications and Reference Data for
specific approval categories.

NOTE
Signal wiring does not require shielding; however, twisted pairs provide
the best results. In order to ensure communication, wiring should be
24AWG or larger and shorter than 5,000 feet (1500 meters) in length.
Do not connect the powered signal wiring to the test terminals. Power may
damage the test diode in the test connection.
Plug and seal unused conduit connections on the electronics housing to avoid
moisture accumulation in the terminal side of the housing.
Excess moisture accumulation may damage the ProBar electronics. If the
connections are not sealed, the ProBar electronics should be remote
mounted with the electrical housing positioned downward for drainage.
Wiring should be installed with a drip loop, and the bottom of the drip loop
should be lower then the conduit connections and the housing.
Grounding the Signal Wiring
Do not run signal wiring in conduit or open trays with power wiring, or near
heavy electrical equipment. Signal wiring may be grounded at any one point
on the signal loop, or it may be left ungrounded. The negative terminal of the
power supply is a recommended grounding point.
Grounding the ProBar Case
The ProBar should always be grounded in accordance with national and
local electrical codes. The most effective ProBar case grounding method is a
direct connection to an earth ground with minimal impedance. Methods for
grounding the ProBar case include:
• Internal Ground Connection: Inside the FIELD TERMINALS side of
the electronics housing is the Internal Ground Connection screw,
which is identified by a ground symbol:
.
NOTE
Grounding the electronics case via threaded conduit connection may not
provide sufficient ground.
Environmental
Considerations
Mount the ProBar to minimize ambient temperature changes. Section 16:
Specifications and Reference Data lists the ProBar temperature
operating limits. Mount the ProBar electronics to avoid vibration and
mechanical shock, and to avoid external contact with corrosive materials.
Access Requirements
When choosing an installation location and position, consider the need for
access to the ProBar.
Process Flange Orientation
Orient the process flanges on a remote mounted ProBar so that process
connections can be made. For safety reasons, orient the drain/vent valves so
that process fluid is directed away from technicians when the valves are used.
In addition, consider the possible need for a testing or calibration input.
Housing Rotation
The electronics housing may be rotated up to 180 degrees (left or right) to
improve field access to the two compartments or to better view the optional
LCD meter. To rotate the housing, release the housing rotation set screw and
turn the housing not more than 180 degrees.
NOTE
Do not rotate the housing greater than 180 degrees. Rotating the housing
greater than 180 degrees will damage the sensor module and void the
warranty.
10-4
Field Wiring and Electrical Considerations
Terminal Side of the
Electronics Housing
Wiring connections are made through the conduit openings on the top
side of the housing. The field terminal side is marked on the electronics
housing. Mount the ProBar so that the terminal side is accessible. A
0.75’’ clearance is required for cover removal. Use a conduit plug on the
unused side of the conduit opening.
Circuit Side of the
Electronics Housing
The circuit compartment should not routinely need to be opened when
the unit is in service; however, provide 0.75-in. clearance if possible to
allow access. A 3-in. clearance is required for cover removal if a meter
is installed.
Exterior of the
Electronics Housing
The integral span and zero push-buttons are located under the
certifications plate on the top of the ProBar. The plate will be blank if no
certifications are ordered.
Cover Installations
Always install the electronics housing covers metal-to-metal to ensure a
proper seal.

COMMISSIONING REMOTE
MOUNTED FLOWMETERS
This section contains four procedures to follow in preparation for
commissioning a remote mounted ProBar:
1. Identify the location and purpose of manifold valves.
2. Zero the electronics.
3. Check for system leaks.
4. Perform a zero calibration.
Before beginning the ProBar commissioning process, you should become
familiar with the location and purpose of the various valves involved.
Figure 12-1 identifies the location of valves for both 5-valve and 3-valve
manifolds, and Table 12-1 identifies the purpose of those valves.

Remote Mount ProBar Commissioning
Zero the Electronics
Before the ProBar electronics are exposed to line pressure, check the
“zero” calibration (or, “dry” zero) by using the following procedure.
1. Open first the equalizer valve(s) MEL and MEH or ME.
2. Close valves MH and ML.
3. Read the ProBar output. It should read within the range 3.98 mA
to 4.02 mA. If the output is outside of this range, trim zero as
described in Section 9: ProBar Electronics Functions.
Check for System Leaks
Check the system for leaks after installation is complete. A leak in a
differential pressure instrument system can produce a difference in
pressure that is larger than the signal itself.
Before the system is filled and/or commissioned, it is a simple matter to
use compressed air or another inert, compressed gas to check for leaks.
The gas pressure must be below the maximum allowed, but at least
equal to the normal operating pressure in order to reveal potential
leaks. A typical pressure used is 100 psig (690 kPa).
Before pressurizing the system, check for leaks by doing the following:
1. Open equalizer valve(s) MEH, MEL or ME to prevent
overpressuring the DP.
2. Close valves PH, PL (unless the piping system is also being
pressure-checked), MV, DVH, DVL.
• If present, also close valves BH and BL or DH and DL.
3. Open valves MH and ML.
4. Install all appropriate tapped plugs.
5. Install a current meter to read the signal, if necessary.
Apply pressure at a convenient point on either the high or low side of
the system. Use a suitable leak detection solution and apply to all of the
impulse piping, valves, manifold, and connections. A leak is indicated
by a continuous stream of bubbles.
5-Valve Manifolds
If a 5-valve manifold is installed, the equalizer valves can be tested by
performing the following after system leaks are repaired and the
system is stable:
1. Close equalizer valves MEH and MEL.
2. Open vent valve MV. There should be no leakage from the
manifold vent.
3. Close vent valve MV.
4. Open equalizer valves MEH and MEL.
5. Bleed off the air and remove the source fitting.
6. Return the system to the original configuration. Use extreme
care when bleeding high temperature fluids. Bleed piping may
need to be installed.
12-3
ProBar Flowmeter
“Calibrate Out”
Temperature Effects
Do not begin this procedure until the system leak check has been
completed and all leaks have been fixed.
The ProBar’s proportional output-to-flow ratio makes a true “zero”
calibration critical for producing accurate measurements. The “zero”
calibration procedure is affected by static pressure and ambient
temperature, but these effects can be removed by calibrating them “out.”
The effect of static pressure is calibrated out by exposing the ProBar
electronics to the line pressure and performing a “zero” or wet
calibration, as described below. In order to calibrate out the effect of
ambient temperature, two aspects should be taken into consideration:
1. The electronics should be located in a place where the ambient
temperature does not change rapidly or vary by more than 10 to
15 °F (26 to 29 °C).
2. When commissioning the electronics, the flowing fluid (condensate/
water for steam service) could bring the sensor to a temperature
significantly different than the temperature during normal
operations. In this situation, perform another “zero” calibration at
least 60 minutes after the ProBar has been commissioned. The
sensor temperature can be monitored using a HART-based
communicator, as described in the Wet Calibration section below.
Although the above effects are relatively small, they significantly affect
the accuracy of the ProBar when used with low flows.
Periodic “zero” calibration and/or commissioning is recommended to
maintain the accuracy of ProBar. The frequency of this type of
maintenance should be established for each individual application.
Zero or Wet Calibration
Follow this procedure to obtain a true zero at static or “pipe” pressure:
1. Open equalizer valves:
• For 5-valve manifolds, open valves MEH and MEL
• For 3-valve manifolds, open valves ME and high side MH
2. Close low side valve ML to prevent generating differential pressure.
12-4
Remote Mount ProBar Commissioning
COMMISSIONING
Complete the following tasks before beginning the
commissioning procedure:
1. Power the ProBar, if required.
2. Connect an appropriate readout instrument so the differential
pressure signal can be monitored.
3. Identify the manifold equalizer valves by their ME prefix.
• 5-valve manifolds have two equalizer valves, MEH and MEL.
• 3-valve manifolds have one equalizer valve, ME.
4. Close all valves before commissioning the system. See Figures 8-4
through 8-10 for valve identification while following the
procedures given below.
Liquid Service below 250 °F
(121 °C)
Refer to Figures 8-5 and 8-6 for electronics location and valve
identification for liquid service at temperatures of 250 °F (121 °C) or
less. See page 12-7 to commission a remote mounted ProBar for liquid
service above 250 °F (121 °C).
1. Ensure that primary instrument valves PH and PL are closed.
2. Open valves ME, ML, and MH.
• For 5-valve manifolds, open valves MEH and MEL.
3. Slowly open valve PL and then PH, which are the primary
instrument valves.
4. Open drain/vent valves DVL and DVH to bleed air out of system.
Bleed until no air is apparent in the liquid.
5. Close valves DVL and DVH.
NOTE
For the alternate electronics location shown in Figure 8-6, open vent
valves VH and VL and bleed until no air is apparent in the liquid.
6. Slowly open vent valve MV to bleed out any entrapped air in
manifold. Bleed until no air is apparent in the liquid.
7. Close vent valve MV.
8. Gently tap the electronics body, valve manifold, and impulse piping
with a small wrench to dislodge any remaining entrapped air.
9. Repeat steps 2, 2A, and 3.
10. Close valve PH.
11. Check the ProBar zero by noting the electronics output — this is
called a wet zero. The electronics should indicate a zero DP
(Differential Pressure) signal. If the signal reads outside the
range 3.98 mA to 4.02 mA, air is probably still in the system;
repeat the procedure from step 2. Trim zero if necessary.
12. Close equalizer valve(s).
• For 3-valve manifolds, close valve ME.
• For 5-valve manifolds, close valves MEH and MEL.
13. Slowly open valve PH. The system is now operational.
For 5-valve manifolds only:
14. Open valve MV. If valve MV is leaking, valves MEH and/or MEL
are not fully closed or require repair. This must be done before
taking any readings.
12-5
ProBar Flowmeter
Gas Service
Follow this procedure for commissioning a remote mounted ProBar for
gas service. Refer to Figures 8-7 and 8-8 for electronics location and
valve identification.
1. For an impulse piping arrangement as shown in Figure 8-7
(vertical pipe) only, open primary instrument valves PH and PL.
2. Open drain valves DH and DL slowly to allow the condensate
to drain.
3. Close valves DH and DL.
4. Ensure that primary instrument valves PH and PL closed.
5. Open valves ME, ML and MH.
• For 5-valve manifolds, open valves MEH and MEL.
6. Slowly open valve PL, the primary high pressure instrument valve.
7. Check electronics zero by noting the electronics reading. The
electronics should indicate a “zero” DP signal. If the signal reads
outside of the range 3.98 mA to 4.02 mA, condensate may be in the
DP electronics or system; repeat the procedure from step 1 to
remove any condensate. A signal outside the range 3.98 mA to 4.02
mA can also be caused by system leaks; check for leaks in system.
8. Close equalizer valve(s).
• For 3-valve manifolds, close valve ME.
• For 5-valve manifolds, close valves MEH and MEL.
9. Slowly open valve PH. The system is now operational.
For 5-valve manifolds only:
10. Open valve MV. If valve MV is leaking, valves MEH and/or MEL
are not fully closed or require repair. This must be done before
taking any readings.

Steam Service or
Liquid Service above
250 °F (121 °C)
Follow this procedure for commissioning a remote mounted ProBar
for steam service or for liquid service at a temperature above 250 °F
(121 °C). Refer to Figures 8-9 and 8-10 for electronics location and
valve identification.
1. Ensure that primary instrument valves PH and PL closed; ME,
ML and MH are closed; and DVL and DVH are closed.
• For 5-valve manifolds, ensure that valves MEH and MEL
are closed.
2. Fill tees with water on each side until water overflows.
3. Open valves MH, ML and equalizer valve ME.
• For 5-valve manifolds, open equalizer valves MEH and MEL.
4. Open valves DVL and DVH.
5. Tap manifold until no air bubbles are visible.
6. Close both valves DVL and DVH.
7. Refill tees with water.
8. Gently tap electronics body, valve manifold, and impulse piping
with a small wrench to dislodge any remaining entrapped air.
9. Check ProBar zero by noting the electronics output — this is
called a wet zero. The electronics should indicate a “zero” DP
signal. If the signal reads outside of the range 3.98 mA to 4.02
mA, air is probably still in the system; repeat this procedure from
step 2. Trim zero if necessary.
10. Close equalizer valve ME.
• For 5-valve manifolds, close equalizer valves MEH and MEL.
11. Replace plugs in tees.
12. Slowly open valves PH and PL. The system is now operational.
For 5-valve manifolds only:
13. Open valve MV. If valve MV is leaking, valves MEH and/or MEL
are not fully closed or require repair. This must be done before
taking any readings.

Installation Options
Options available with the ProBar can ease installation and enhance
the security of control systems. These options include the integral zero
and span adjustments, LCD meters, mounting brackets, custom
configurations, the level flange, the traditional flange, optional bolt
materials, and the transient protection terminal block.
SAFETY MESSAGES
Procedures and instructions in this section may require special
precautions to ensure the safety of the personnel performing the
operations. Information that raises potential safety issues is indicated
by a warning symbol ( ). Refer to the following safety messages before
performing an operation preceded by this symbol.
Explosions could result in death or serious injury:
• Do not remove the transmitter cover in explosive atmospheres when the circuit is alive.
• Before connecting a HART-based communicator in an explosive atmosphere, make
sure the instruments in the loop are installed in accordance with intrinsically safe or
non-incendive field wiring practices.
• Verify that the operating atmosphere of the transmitter is consistent with the
appropriate hazardous locations certifications.
• Both transmitter covers must be fully engaged to meet explosion-proof requirements.
Electrical shock can result in death or serious injury.
• Avoid contact with the leads and the terminals.
INTEGRAL
ZERO AND SPAN
ADJUSTMENT OPTIONS
The integral zero and span adjustments can be used for adjusting the
analog output without the use of a communicator. Several options are
available to customize the local zero and span adjustments. The J1
option only provides the external zero adjustment that enables the user
to rezero the flowmeter locally. The J3 option excludes both the zero and
span adjustments for security purposes.
The push-button span and zero adjustments are hidden by the
certifications label on top of the flowmeter. Loosen the label screw and
rotate the label 180 degrees counterclockwise to expose the adjustments.
13-1
ProBar Flowmeter
Disabling the
Zero and Span
Adjustments
For security reasons, or to prevent accidental changes to the
configuration data, there are three methods of controlling the local zero
and span adjustments:
Method 1: flowmeter Security Jumper
Enabling the flowmeter security jumper on the circuit board prevents
changes to flowmeter configuration information by both the HART
Communicator and the local zero and span adjustments (see
Flowmeter Security on page 9-4).
Method 2: Communicator Software Lockout Sequence
The communicator software lockout sequence disables only the span
and zero adjustments; changes can still be made using the HART
communicator (see page 9-14).
Method 3: Remove the Zero and Span Buttons
To remove the local zero and span buttons, use a small screwdriver to
remove the blue plastic cover plate securing the buttons to the
flowmeter housing. After you remove the cover plate, the button
assemblies – including buttons, springs, and magnets – will slide out.
If you intend to use the button at some time in the future, store the
buttons separately to ensure that the magnets maintain their proper
magnetic strength.
LCD METER
The LCD meter provides local indication of the output, and abbreviated
diagnostic messages governing flowmeter operation. The meter is
located on the electronics module side of the flowmeter, maintaining
direct access to the signal terminals. An extended cover is required to
accommodate the meter.
The meter features a two-line display that accommodates five digits for
reporting the process variable on the top line, and six characters for
displaying engineering units on the bottom line(1). And in addition to
units of pressure, the new LCD meter is capable of displaying flow and
volume units. The meter uses both lines to display diagnostic messages.
You can configure the meter to display the following information:
• Engineering Units
• Percent of Range
• Alternating between any two of the above

The meter kit includes:
• one LCD meter assembly
• one extended cover with cover O-ring installed
• two nylon standoffs
• two captive screws
• one ten -pin interconnection header
Use the following procedure and Figure 13-1 to install the LCD meter.
If the meter is an upgrade from a previous version, upgrade the
electronics board before attempting to install the meter.
1. If the flowmeter is installed in a loop, secure the loop and
disconnect power.
2. Remove the flowmeter cover opposite the field terminal side. Do
not remove the instrument covers in explosive environments
when the circuit is alive.
3. Remove the failure mode and alarm jumpers from the electronics
module, and insert them in their new positions above and below
the meter readout on the meter assembly.
NOTE
On previous versions, remove only the alarm jumper.
4. Insert the interconnection header in the ten-pin(1) socket exposed
by removal of the jumpers.
5. Remove the two captive screws from the electronics module. To do
so, loosen the screws to release the module, then pull out the
screws until they are stopped by the captive thread inside of the
circuit board standoffs. Continue loosening the screws and
remove them.
6. Rotate the electronics housing up to 180 degrees (left or right) to
improve field access to the two compartments or to better view
the optional LCD meter. To rotate the housing, release the
housing rotation set screw and turn the housing not more than
180 degrees from the orientation shown in Figure 13-2. To rotate
the housing greater than 180 degrees, follow Steps 1–6 of the
disassembly procedure in Section 15: Troubleshooting.
(1) Previous versions of the meter use a six-pin connector.
See Safety Messages on page 13-1 for complete warning information.
13-3
ProBar Flowmeter
NOTE
Do not rotate the housing greater than 180 degrees without first
following the disassembly procedure in Section 15: Troubleshooting.
Rotating the housing greater than 180 degrees will damage the sensor
module and void the Rosemount warranty.
7. Decide which direction to orient the meter. Insert the long meter
screws into the two holes on the meter assembly that coincide
with the holes on the electronics module. You can install the
meter in 90-degree increments for easy viewing. Position one of
the four connectors on the back of the meter assembly to accept
the interconnection header.
8. Attach the meter assembly to the electronics module by threading
the screws into the captive threads and attaching the meter
assembly to the interconnection pins. Tighten the screws to
secure the meter assembly and electronics board in place.
9. Attach the extended cover, and tighten. Flowmeter covers must be
fully engaged to meet explosion proof requirements and to
achieve the proper environmental seal.
Note the following LCD temperature limits:
Operating: –4 to 175 °F (–20 to 80 °C)
Storage: –40 to 185 °F (–40 to 85 °C)
NOTE
Electronics board revision 5.3 or later (all shrouded designs) have
increased functionality that allows verification testing of alarm current
levels. If you repair or replace the flowmeter electronics board, sensor
module or LCD meter, it is recommended that you verify the flowmeter
alarm level before you return the flowmeter to service (see Alarm
Level Verification on page 9-3).

operating messages appearing last. To determine the cause of a
message, use a Model 275 HART Communicator to further interrogate
the flowmeter. A description of each LCD diagnostic message follows.
See Safety Messages on page 13-1 for complete warning information.
Installation Options
Error
Error messages appear on the LCD meter display to inform you of
serious problems effecting the operation of the flowmeter. The meter
displays an error message until the error condition is corrected, and the
analog output is driven to the specified alarm level. No other flowmeter
information is displayed during an alarm condition.
FAIL(1)
The flowmeter CPU board and the sensor module are incompatible.
If you encounter this message, contact Dieterich Standard Inc. at
303-530-3600 if you need assistance.
FAIL MODULE
The sensor module is disconnected or is malfunctioning. Verify that the
sensor module ribbon cable is connected to the back of the electronics
board. If the ribbon cable is properly connected, there is a problem
within the sensor module. Possible sources of problems include:
• Pressure or temperature updates are not being received in the
sensor module
• A non-volatile memory fault that will effect flowmeter operation
has been detected in the module by the memory verification
routine
Some non-volatile memory faults are user-repairable. Use a Model 275
HART Communicator to diagnose the error and determine if it is
repairable. Any error message that ends in “FACTORY” is not
repairable. In cases of non user-repairable errors, you must replace the
sensor module. See on page 15-3, or contact Dieterich Standard Inc. at
303-530-3600 if you need assistance.

compartment labelled “FIELD TERMINALS.”
Loosen the two small screws located at the 9 o'clock and 4 o'clock
positions, and pull the entire terminal block out to remove it.
NOTE
If removing the terminal block from the housing of a previous version of
the flowmeter, you will have to manually disconnect the power leads
from the rear of the terminal block before completely separating it from
the housing.
REMOVE THE
ELECTRONICS BOARD
The flowmeter electronics board is located in the compartment opposite
the terminal side. To remove the electronics board perform the
following procedure:
1. Remove the housing cover opposite the field terminal side.
2. Loosen the two captive screws that anchor the board to the
housing. The electronics board is electrostatically sensitive;
observe handling precautions for static-sensitive components.
NOTE
If you are disassembling a flowmeter with a LCD meter, loosen the two
captive screws that are visible on the right and left sides of the meter
display. The two screws anchor the LCD meter to the electronics board
and the electronics board to the housing.
3. Slowly pull the electronics board out of the housing. With the two
captive screws free of the flowmeter housing, only the sensor
module ribbon cable holds the board to the housing.
NOTE
Previous versions of the electronics board utilize a snap-in power plug
and receptacle. Carefully unsnap the power plug from the receptacle to
free the board from the power cord.
4. Disconnect the sensor module ribbon cable to release the

Troubleshooting
REMOVE THE SENSOR
MODULE FROM THE
ELECTRONICS HOUSING
(FOR SERVICE-TYPE PROBAR UC,
UNCALIBRATED PROBAR ONLY)
1. Carefully tuck the cable connector completely inside the internal shroud.
IMPORTANT
Do not remove the housing until after the cable connector is completely
inside the internal shroud. The shroud protects the cable from damage
that can occur when the housing is rotated.
2. Loosen the housing rotation set screw with a 9/64-inch hex wrench;
back off one full turn.
IMPORTANT
To prevent damage to the sensor module ribbon cable, disconnect it
from the electronics board before you remove the sensor module from
the electrical housing.
3. Unscrew the housing from the module. Make sure the shroud and
sensor cable do not catch on the housing.
IMPORTANT
Make sure the sensor ribbon cable and internal shroud remain completely free
of the housing as you rotate it. Damage can occur to the cable if the internal
shroud and sensor cable become hung-up and rotate with the housing.
ATTACH THE SENSOR
MODULE TO THE
ELECTRONICS
HOUSING BLOCK
1. Inspect all cover and housing (non-process-wetted) o-rings and
replace if necessary. Lightly grease them with silicone lubricant
to ensure a good seal.
2. Carefully tuck the cable connector completely inside the internal
shroud. To do so, turn the shroud and cable counterclockwise one
rotation to tighten the cable.
3. Lower the electronics housing onto the module; guide the internal
shroud and cable through the housing and into the external shroud.
4. Turn the housing clockwise to fasten it to the module.
IMPORTANT
To prevent damage to the cable connector, watch the cable and shroud
as you attach the housing to the module. Make sure the cable connector
does not slip out of the internal shroud and begin to rotate with the
housing. Reinsert the cable connector into the shroud if it escapes
before the housing is fully fastened.
5. Thread the housing completely onto the sensor module. To comply
with explosion-proof requirements, the housing must be no more
than one full turn from flush with the sensor module.
6. Tighten the housing rotation set screw using a 9/64-inch hex wrench.
NOTE
Electronics board revision 5.3.163 or later (all shrouded designs) have
increased functionality that allows verification testing of alarm current
levels. If you repair or replace the electronics board, sensor module or
LCD meter, it is recommended that you verify the transmitter alarm
level before you return the electronics to service.

INTRODUCTION
HART Communicator
This appendix provides basic communicator information on the HART
Communicator Model 275 when used with a Model 8900V ProBar
Volumentric Flowmeter.
This brief appendix will familiarize you with the HART Communicator
but is not meant to replace the HART Communicator product manual.
For complete information on the HART Communicator, refer to the
HART Communicator Product Manual p/n 00275-8026-0001.
NOTE
You must upgrade the software in your HART Communicator in order to
take advantage of the additional features of the improved ProBar. If you
initiate communication with an improved ProBar using a Communicator
that has a previous version of the flowmeter Device Descriptors (DDs),
the communicator will display the following message:
NOTICE: Upgrade 275 software to access XMTR function.
Continue with old description?
If you select YES, the communicator will communicate properly with
the flowmeter using the existing ProBar DDs. However, software
features added since the revision of the DDs in the communicator will
not be accessible. If you select NO, the communicator will default to a
generic flowmeter functionality.
Contact your nearest Rosemount Service Center or Sales
Representative to upgrade your communicator
SAFETY MESSAGES
Procedures and instructions in this section may require special
precautions to ensure the safety of the personnel performing the
operations. Information that raises potential safety issues is indicated
by a warning symbol ( ). Refer to the following safety messages before
performing an operation preceded by this symbol.
Explosions can result in death or serious injury.
• Do not remove the flowmeter covers in explosive environments when the
circuit is alive.
• Both flowmeter covers must be fully engaged to meet
explosion-proof requirements.
• Before connecting a communicator in an explosive atmosphere, make sure the
instruments in the loop are installed in accordance with intrinsically safe or
nonincendive field wiring practices.

ProBar Flowmeter
The HART Communicator Model 275 can interface with a flowmeter
from the control room, the instrument site, or any wiring termination
point in the loop through the rear connection panel as shown in Figure
A-1. Do not make connections to the serial port or NiCad recharger jack
in an explosive atmosphere. To communicate, connect the HART
Communicator in parallel with the instrument or load resistor. The
connections are non-polarized. Before connecting the HART
Communicator in an explosive atmosphere, make sure the instruments
in the loop are installed in accordance with intrinsically safe or
nonincendive field wiring practices.
CONNECTIONS AND
HARDWARE
NOTE
The HART Communicator needs a minimum of 250 ohms resistance in
the loop to function properly.
The HART Communicator is not a measurement device and does not need
to be calibrated; it is a communications device through which you can read
and adjust the flowmeter configuration information. All variable outputs
displayed by the communicator are functions of the flowmeter.

COMMUNICATOR KEYS
The keys of the HART Commuincator include action, function,
alphanumeric, and shift keys

Function Keys
Action Keys
Alphanumeric Keys
275-011AB
Shift Keys
Action Keys
As shown in Figure A-4, the action keys are the six blue, white, and
black keys located above the alphanumeric keys. The function of each
key is described as follows:
ON/OFF Key
Use this key to power the HART Communicator. When the
communicator is turned on, it searches for a flowmeter on the 4–20 mA
loop. If a device is not found, the communicator displays the message,
“No Device Found. Press OK.”
If a HART-compatible device is found, the communicator displays the
Online Menu with device ID and tag.
Directional Keys
Use these keys to move the cursor up, down, left, or right. The right
arrow key also selects menu options, and the left arrow key returns to
the previous menu.
A-8
Appendix A
HOT Key
Use this key to quickly access important, user-selectable options when
connected to a HART-compatible device. Pressing the Hot Key turns the
HART Communicator on and displays the Hot Key Menu. See
Customizing the Hot Key Menu in the HART Communicator
manual for more information.
Function Keys
F3
Alphanumeric and Shift Keys
Use the four software-defined function keys, located below the LCD, to
perform software functions. On any given menu, the label appearing
above a function key indicates the function of that key for the current
menu. As you move among menus, different function key labels appear
over the four keys. For example, in menus providing access to on-line
help, the HELP label may appear above the F1 key. In menus providing
access to the Online Menu, the HOME label may appear above the F3 key.
Simply press the key to activate the function. See your HART
Communicator manual for details on specific function key definitions.
The alphanumeric keys (Figure A-5) perform two functions: the fast
selection of menu options and data entry.
275-0383A
FIGURE A-5.
HART Communicator Alphanumeric
and Shift Keys.
Data Entry
Some menus require data entry. Use the alphanumeric and shift keys to
enter all alphanumeric information into the HART Communicator. If
you press an alphanumeric key alone from within an edit menu, the
bold character in the center of the key appears. These large characters
include the numbers zero through nine, the decimal point (.), and the
dash symbol (—).
To enter an alphabetic character, first press the shift key that
corresponds to the position of the letter you want on the alphanumeric
key. Then press the alphanumeric key. For example, to enter the letter
R, first press the right shift key, then the “6” key (see Figure A-6). Do
not press these keys simultaneously, but one after the other.

Fast Key Sequences
HART fast key sequences provide quick on-line access to flowmeter
variables and functions. Instead of stepping your way through the menu
structure using the action keys, you can press a HART fast key sequence
to move from the Online Menu to the desired variable or function. Onscreen instructions guide you through the rest of the screens.
Fast Key Sequence Conventions
The fast key sequences for the Model 275 use the following conventions
for their identification:

Fast Key Sequence Example
HART fast key sequences are made up of the series of numbers
corresponding to the individual options in each step of the menu
structure. For example, from the Online Menu you can change the
Date. Following the menu structure, press 1 to reach Device Setup,
press 3 for Basic Setup, press 4 for Device Info, press 5 for Date. The
corresponding HART fast key sequence is 1,3,4,5.
HART fast keys are operational only from the Online Menu. If you use
them consistently, you will need to return to the Online Menu by
pressing HOME (F3) when it is available. If you do not start at the Online
Menu, the HART fast key sequences will not function properly.
Use Table A-1, an alphabetical listing of every on-line function, to find
the corresponding HART fast key sequences. These codes are applicable
only to ProBar flowmeters and the HART Communicator.

MENUS AND FUNCTIONS
The HART Communicator is a menu driven system. Each screen provides
a menu of options that can be selected as outlined above, or provides
direction for input of data, warnings, messages, or other instructions.
Main Menu
When the HART Communicator is turned on, one of two menus will
appear. If the HART Communicator is connected to an operating loop,
the communicator will find the device and display the Online Menu (see
below). If it is not connected to a loop, the communicator will indicate
that no device was found. When you press OK (F4), it will display the
Main menu.
The Main menu provides the following options:
• Offline–The Offline option provides access to offline configuration
data and simulation functions.
• Online–The Online option checks for a device and if it finds one,
brings up the Online Menu.
• Transfer–The Transfer option provides access to options for
transferring data either from the HART Communicator (memory)
to the flowmeter (device) or vice versa. Transfer is used to move
off-line data from the HART Communicator to the flowmeter, or
to retrieve data from a flowmeter for off-line revision.
NOTE
Online communication with the flowmeter automatically loads the
current flowmeter data to the HART Communicator. Changes in on-line
data are made active by pressing SEND (F2). The transfer function is
used only for off-line data retrieval and sending.
• Frequency Device–The Frequency Device option displays the
frequency output and corresponding pressure output of currentto-pressure flowmeters.
• Utility–The Utility option provides access to the contrast control
for the HART Communicator LCD screen and to the autopoll
setting used in multidrop applications.
Once selecting a Main menu option, the HART Communicator provides
the information you need to complete the operation. If further details
are required, consult the HART Communicator manual.
A-11
ProBar Flowmeter
Online Menu
The Online Menu can be selected from the Main menu as outlined
above, or it may appear automatically if the HART Communicator is
connected to an active loop and can detect an operating flowmeter.
NOTE
The Main menu can be accessed from the Online Menu. Press the left
arrow action key to deactivate the on-line communication with the
flowmeter and to activate the Main menu options.
When configuration variables are reset in the on-line mode, the new
settings are not activated until the data is sent to the flowmeter.
Press SEND (F2) when it is activated to update the process variables of
the flowmeter.
On-line mode is used for direct evaluation of a particular meter, reconfiguration, changing parameters, maintenance, and other functions.
