SYSTEM DESCRIPTION
The Rosemount® 8700 Series Magnetic Flowmeter System consists of a
sensor and transmitter, and measures volumetric flow rate by detecting the
velocity of a conductive liquid that passes through a magnetic field.
There are four Rosemount magnetic flowmeter sensors:
•
Flanged Rosemount 8705
•
Flanged High-Signal Rosemount 8707
•
Wafer-Style Rosemount 8711
•
Sanitary Rosemount 8721
There are two Rosemount magnetic flowmeter transmitters:
•
Rosemount 8712
•
Rosemount 8732
The sensor is installed in-line with process piping — either vertically or
horizontally. Coils located on opposite sides of the sensor create a magnetic
field. Electrodes located perpendicular to the coils make contact with the
process fluid. A conductive liquid moving through the magnetic field
generates a voltage at the two electrodes that is proportional to the flow
velocity.
The transmitter drives the coils to generate a magnetic field, and electronically
conditions the voltage detected by the electrodes to provide a flow signal. The
transmitter can be integrally or remotely mounted from the sensor.
This manual is designed to assist in the installation and operation of the
Rosemount 8732 Magnetic Flowmeter Transmitter and the Rosemount 8700
Series Magnetic Flowmeter Sensors.

The sensor liner is vulnerable to handling damage. Never place anything through the sensor
for the purpose of lifting or gaining leverage. Liner damage can render the sensor useless.
To avoid possible damage to the sensor liner ends, do not use metallic or spiral-wound
gaskets. If frequent removal is anticipated, take precautions to protect the liner ends. Short
spool pieces attached to the sensor ends are often used for protection.
Correct flange bolt tightening is crucial for proper sensor operation and life. All bolts must be
tightened in the proper sequence to the specified torque limits. Failure to observe these
instructions could result in severe damage to the sensor lining and possible sensor
replacement.
Emerson Process Management can supply lining protectors to prevent liner damage during
removal, installation, and excessive bolt torquing.

PRE-INSTALLATION
Before installing the Rosemount 8732 Magnetic Flowmeter Transmitter, there
are several pre-installation steps that should be completed to make the
installation process easier:
MECHANICAL
CONSIDERATIONS
Protective conductor (grounding) terminal
•
Identify the options and configurations that apply to your application
•
Set the hardware switches if necessary
•
Consider mechanical, electrical, and environmental requirements
The mounting site for the 8732 transmitter should provide enough room for
secure mounting, easy access to conduit ports, full opening of the transmitter
covers, and easy readability of the LOI screen (see Figure 2-1). The
transmitter should be mounted in a manner that prevents moisture in conduit
from collecting in the transmitter.
If the 8732 is mounted remotely from the sensor, it is not subject to limitations
that might apply to the sensor.

Hardware
Jumpers/Switches
The 8732 Profibus PA electronics board is equipped with two user-selectable
hardware switches. These switches do not have any functionality and should
be left in the default positions as listed below:
Simulate Enable
OFF
Transmitter Security
OFF
Changing the switch position will have no effect on the functionality of the
electronics.
Conduit Ports and
Connections
Both the sensor and transmitter junction boxes have ports for 1/2-inch NPT
conduit connections, with optional CM20 and PG 13.5 adapter connections
available. These connections should be made in accordance with national,
local or plant electrical codes. Unused ports should be sealed with metal
plugs and PTFE tape or other thread sealant. Connections should also be
made in accordance with area approval requirements, see examples below
for details. Proper electrical installation is necessary to prevent errors due to
electrical noise and interference. Separate conduits are not necessary for the
coil drive and signal cables connecting the transmitter to the sensor, but a
dedicated conduit line between each transmitter and sensor is required. A
shielded cable must be used.
Example 1: Installing flanged sensors into an IP68 area. Sensors must be
installed with IP68 cable glands and cable to maintain IP68 rating. Unused
conduit connections must be properly sealed to prevent water ingress. For
added protection, dielectric gel can be used to pot the sensor terminal block.
Consult technical document 00840-0100-4750 when installing meters into an
IP68 installation.
Example 2: Installing flowmeters into explosion proof/flameproof areas.
Conduit connections and conduit must be rated for use in the hazardous area
to maintain flowmeter approval rating. Consult Appendix B: of this manual for
installation requirements for hazardous areas.
Conduit Cables
2-4
Run the appropriate size cable through the conduit connections in your
magnetic flowmeter system. Run the power cable from the power source to
the transmitter. Do not run power cables and output signal cables in the same
conduit. For remote mount installations, run the coil drive and electrode
cables between the flowmeter and transmitter. Refer to Electrical
Considerations for wire type. Prepare the ends of the coil drive and electrode
cables as shown in Figure 2-2. Limit the unshielded wire length to 1-in. on
both the electrode and coil drive cables. Excessive lead length or failure to
connect cable shields can create electrical noise resulting in unstable meter
readings.

SENSOR CONNECTIONS
This section covers the steps required to physically install the transmitter
including wiring and calibration.
Rosemount Sensors
To connect the transmitter to a non-Rosemount sensor, refer to the
appropriate wiring diagram in “Universal Sensor Wiring Diagrams” on
page E-1. The calibration procedure listed is not required for use with
Rosemount sensors.
Transmitter to Sensor
Wiring
Flanged and wafer sensors have two conduit ports as shown in Figure 2-7.
Either one may be used for both the coil drive and electrode cables. Use the
stainless steel plug that is provided to seal the unused conduit port. Use
PTFE tape or thread sealant appropriate for the installation when sealing the
conduit.
A single dedicated conduit run for the coil drive and electrode cables is
needed between a sensor and a remote transmitter. Bundled cables in a
single conduit are likely to create interference and noise problems in your
system. Use one set of cables per conduit run. See Figure 2-7 for proper
conduit installation diagram and Table 2-2 for recommended cable. For
integral and remote wiring diagrams refer to Figure 2-9.

Rosemount 8732
Rosemount recommends using the combination signal and coil drive for N5,
E5 approved sensors for optimum performance.
Remote transmitter installations require equal lengths of signal and coil drive
cables. Integrally mounted transmitters are factory wired and do not require
interconnecting cables.
Lengths from 5 to 1,000 feet (1.5 to 300 meters) may be specified, and will be
shipped with the sensor.
Conduit Cables
Run the appropriate size cable through the conduit connections in your
magnetic flowmeter system. Run the power cable from the power source to
the transmitter. Run the coil drive and electrode cables between the sensor
and transmitter.
Prepare the ends of the coil drive and electrode cables as shown in Figure
2-8. Limit the unshielded wire length to 1-inch on both the electrode and coil
drive cables.
NOTE
Excessive lead length or failure to connect cable shields can create electrical
noise resulting in unstable meter readings.

This section covers basic operation, software functionality, and basic
configuration procedures for the Rosemount 8732E Magnetic Flowmeter
Transmitter with Profibus PA. For more information about the Profibus PA
technology and the function blocks used in the transmitter, refer to
Appendix F: Physical Block and Appendix G.
Calibration
Rosemount sensors are wet calibrated at the factory. They do not need
further calibration during installation.
Each Profibus PA configuration tool or host device has a different way of
displaying and performing configurations. Some will use Device Descriptions
(DD) and DD Methods to make configuring and displaying data consistent
across host platforms. There is no requirement that a configuration tool or
host support these features. This section describes how to reconfigure the
device manually.
QUICK START-UP
Once the magnetic flowmeter system is installed and communication is
established, configuration of the transmitter must be completed. The standard
transmitter configuration, without Option Code C1, Custom Configuration, is
shipped with the following parameters:

A unique sensor calibration number, imprinted on the sensor tag, enables any
Rosemount sensor to be used with any Rosemount transmitter without further
calibration. Rosemount flow lab tests determine individual sensor output
characteristics. The characteristics are identified by a 16-digit calibration
number. In a Profibus PA environment, the 8732E can be configured using an
8732E Profibus PA LOI or a Simatic PDM. Please see Section 4 for 8732E PA
LOI and PDM information.

Rosemount 8732
The calibration number is more than a correction factor, or K- factor, for the
sensor. The first five digits represent the low frequency gain. The ninth
through thirteenth digits represent the high frequency gain. Both numbers are
normalized from an ideal number of 10000. Standard configurations use the
low frequency gain, but in noisy applications it may be worthwhile to switch to
the higher frequency. An additional transmitter procedure, called Auto Zero, is
recommended to perform at the higher coil drive frequency. The seventh and
eighth digits represent the zero offset at both frequencies where the nominal
value is 50. Empty pipe functionality is a transmitter feature that is controlled
by a parameter in the transducer block. To turn off this feature, see
Appendix C.
ASSIGNING DEVICE TAG
AND NODE ADDRESS
The 8732E Magnetic Flowmeter Transmitter is shipped with a blank tag. The
device is shipped with a default address of 126.
If the tag or address needs to be changed, use the features of the
configuration tool. The tools do the following:
•
Change the tag to a new value.
•
Change the address to a new address.
BASIC SETUP
AI Block
3-2
The Analog Input (AI) function block processes field device measurements
and makes them available to the master. The output value from the AI block is
in engineering units and contains a status indicating the quality of the
measurement. The measuring device may have several measurements or
derived values available in different channels. Use the channel number to
define the variable that the AI block processes. The 8732E transmitter only
supports “Flow” as AI Block variable.

PV
The process variables (PV) measure flow in several ways that reflect your
needs and the configuration of your flowmeter. When commissioning a
flowmeter, review each process variable, its function and output, and take
corrective action if necessary before using the flowmeter in a
process application
PV Value – The actual measured flow rate in the line. Use the Process
Variable Units function to select the units for your application.
PV Status – The status of the process variable. This indicates whether the
reported flow rate is “good”, “uncertain”, or “bad”.
PV Value
The PV Value shows the current measured flow rate.
PV Status
The PV Status shows the health of the PV Value.
Good - The PV Value is valid and the flowmeter system is operating normally.
Uncertain - The PV Value is being reported, but a condition exists that is
potentially compromising the measurement. This condition could be caused
by a problem with the flowmeter or the process.
Bad - A problem exists with the flowmeter system that has resulted in a
potentially faulty flow measurement. Consult status and diagnostic
information to identify the problem.
BASIC SETUP
The basic configuration functions of the Rosemount 8732 must be set for all
applications of the transmitter in a magnetic flowmeter system. If your
application requires the advanced functionality features of the Rosemount
8732, see Section 4 of this manual.

Upper Range Value
Rosemount 8732
This parameter set the flow rate in engineering units that corresponds to
100% flow. This parameter is configured in the Transducer Block.
The Upper Range Value can be set for both forward or reverse flow rates.
Flow in the forward direction is represented by positive values and flow in the
reverse direction is represented by negative values. The URV can be any
value from –43.3 ft/s to +43.3 ft/s (-13.2 m/s to +13.2 m/s), as long as it is at
least 1 ft/s (0.3 m/s) from the lower range value (LRV). The URV can be set to
a value less than the lower range value.
NOTE
Line size and density must be selected prior to configuration of URV and LRV.
Lower Range Value
This parameter sets the flow rate in engineering units that corresponds to 0%
flow. This parameter is configured in the Transducer Block.
Set the lower range value (LRV) to change the size of the range (or span)
between the URV and LRV. Under normal circumstances, the LRV should be
set to a value near the minimum expected flow rate to maximize resolution.
The LRV must be between –43.3 ft/s to +43.3 ft/s (-13.2 m/s to +13.2 m/s).
NOTE
Line size and density must be selected prior to configuration of URV and LRV.
The minimum allowable span between the URV and LRV is 1 ft/s (0.3 m/s).
Do not set the LRV within 1 ft/s (0.3 m/s) of the URV. For example, if the URV
is set to 15.67 ft/s (4.8 m/s) and if the desired URV is greater than the LRV,
then the highest allowable LRV setting would be 14.67 ft/s (4.5 m/s). If the
desired URV is less than the LRV, then the lowest allowable LRV would be
16.67 ft/s (5.1 m/s).
Calibration Number
The sensor calibration number is a 16-digit number used to identify sensors
calibrated at the Rosemount factory. The calibration number is also printed
inside the sensor terminal block or on the sensor name plate. The number
provides detailed calibration information to the Rosemount 8732. To function
properly within accuracy specifications, the number stored in the transmitter
must match the calibration number on the sensor exactly. This parameter is
configured in the Transducer Block.
NOTE
Sensors from manufacturers other than Rosemount Inc. can also be
calibrated at the Rosemount factory. Check the sensor for Rosemount
calibration tags to determine if a 16-digit sensor calibration number exists for
your sensor.

NOTE
Be sure the calibration number reflects a calibration to a Rosemount
reference transmitter. If the calibration number was generated by a means
other than a certified Rosemount flow lab, accuracy of the system may be
compromised.
If your sensor is not a Rosemount sensor and was not calibrated at the
Rosemount factory, contact your Rosemount representative for assistance.
If your sensor is imprinted with an eight-digit number or a k-factor, check in
the sensor wiring compartment for the sixteen-digit calibration number. If
there is no serial number, contact the factory for a proper conversion.
Damping
Adjustable between 0.0 and 256 seconds. This parameter is configured in the
Transducer Block.
Damping allows selection of a response time, in seconds, to a step change in
flow rate. It is most often used to smooth fluctuations in output.

INTRODUCTION
This section contains information for advanced configuration parameters and
diagnostics.
The software configuration settings for the Rosemount 8732 can be accessed
through an 8732 LOI or by using a Class 2 Master. Before operating the
Rosemount 8732 in an actual installation, you should review all of the factory
set configuration data to ensure that they reflect the current application.
LOCAL OPERATOR
INTERFACE
The optional Local Operator Interface (LOI) provides an operator
communications centre for the 8732. By using the LOI, the operator can
access some of the transmitter function - totalizer, basic set-up, or other
functions under the detailed set-up. The LOI is integral to the transmitter
electronics. If you need the added functionality, or if your transmitter does not
have an LOI, you must use a configuration tool such as the Simatic PDM tool.
Basic Features
The basic features of the LOI include 4 navigational arrow keys which are
optical switches that are used to access the menu structure. See Figure
below:

Class 2 Masters
Rosemount 8732
There are a number of available PROFIBUS configuration tools. These Class
2 Masters are manufacturer-independent tools for the operation,
configuration, maintenance, and diagnosis of intelligent field devices. Device
descriptor based Class 2 Masters allow 100% configuration capability on the
8732E Profibus PA transmitter.
Class 2 Masters always need to be connected to the DP segment. They
cannot be directly connected to a PA segment.
DIAGNOSTICS
Diagnostics are used to verify that the transmitter is functioning properly, to
assist in troubleshooting, to identify potential causes of error messages, and
to verify the health of the transmitter and sensor. All the diagnostic test can be
initiated through the use of a Class 2 Master. Some diagnostics can be
accessed using the LOI.
Rosemount offers several different diagnostic suites providing various
functionality.
Standard diagnostics included with every Rosemount 8732 transmitter are
Empty Pipe detection, Electronics Temperature monitoring, Coil Fault
detection, and various loop and transmitter tests.
Advanced diagnostics suite option one (D01 option) contains advanced
diagnostics for High Process Noise detection and Grounding and Wiring fault
detection.
Advanced diagnostics suite option two (D02 option) contains advanced
diagnostics for the 8714i Meter Verification. This diagnostic is used to verify
the accuracy and performance of the magnetic flow meter installation.
Empty Pipe Detection
Turn the empty pipe diagnostic on or off as required by the application. For
more details on the empty pipe diagnostic, see Appendix C: Diagnostics.
Electronics Temperature Out of Range
Turn the electronics temperature diagnostic on or off as required by the
application. For more details on the electronics temperature diagnostic, see
Appendix C: Diagnostics.

Rosemount 8732
Trims
Trims are used to calibrate the transmitter, re-zero the transmitter, and
calibrate the transmitter with another manufacturer’s sensor. Proceed with
caution whenever performing a trim function.
Electronics Trim
Electronics trim is the function by which the factory calibrates the transmitter.
This procedure is rarely needed by customers. It is only necessary if you
suspect the Rosemount 8732E is no longer accurate. A Rosemount 8714
Calibration Standard is required to complete an Electronics trim. Attempting
an Electronics trim without a Rosemount 8714 Calibration Standard may
result in an inaccurate transmitter or an error message. Electronics trim must
be performed only with the coil drive mode set to 5 Hz and with a nominal
sensor calibration number stored in the memory.
NOTE
Attempting an Electronics trim without a Rosemount 8714 may result in an
inaccurate transmitter, or an “ELECTRONICS TRIM FAILURE” message may
appear. If this message occurs, no values were changed in the transmitter.
Simply power down the Rosemount 8732E to clear the message.
To simulate a nominal sensor with the Rosemount 8714, you must change the
following parameters in the Rosemount 8732E:
1.
Sensor Calibration Number—1000015010000000
2.
Units—ft/s
3.
Coil Drive Frequency - 5 Hz
The instructions for changing the Sensor Calibration Number and Units are
located in “Flow Units” on page 3-7. Instructions for changing the Coil Drive
Frequency can be found on page 4-14 in this section.
Set the loop to manual, if necessary, before you begin. Complete the following
steps:
4-10
1.
Power down the transmitter.
2.
Connect the transmitter to a Rosemount 8714 Calibration Standard.
3.
Power up the transmitter with the Rosemount 8714 connected and
read the flow rate. The electronics need about a 5-minute warm-up
time to stabilize.
4.
Set the 8714 calibrator to the 30 ft/s setting.
5.
The flow rate reading after warm-up should be between 29.97 and
30.03 ft/s.
6.
If the reading is within the range, return the transmitter to the original
configuration parameters.
7.
If the reading is not within this range, initiate an Electronics trim with
the Profibus PA configuration tool. The Electronics trim takes about
90 seconds to complete. No transmitter adjustments are required.

Rosemount 8732
Universal Trim
The Universal Trim function enables the Rosemount 8732E to calibrate
sensors that were not calibrated at the Rosemount factory. The function is
activated as one step in a procedure known as in-process calibration. If your
Rosemount sensor has a 16-digit calibration number, in-process calibration is
not required. If it does not, or if your sensor is made by another manufacturer,
complete the following steps for in-process calibration.
1.
Determine the flow rate of the process fluid in the sensor.
NOTE
The flow rate in the line can be determined by using another sensor in the
line, by counting the revolutions of a centrifugal pump, or by performing a
bucket test to determine how fast a given volume is filled by the process fluid.
2.
Complete the Universal Trim function.
3.
When the routine is completed, the sensor is ready for use.
Auto Zero
The Auto Zero function initializes the transmitter for use with the 37 Hz coil
drive mode only. Run this function only with the transmitter and sensor
installed in the process. The sensor must be filled with process fluid at zero
flow. Before running the Auto Zero function, be sure the coil drive mode is set
to 37 Hz (Auto Zero will not run with the coil drive frequency set at 5 Hz).
Set the loop to manual if necessary and begin the Auto Zero procedure. The
transmitter completes the procedure automatically in about 90 seconds. A
symbol appears in the lower right-hand corner of the display to indicate that
the procedure is running.
Master Reset
The master reset is a function that the user can execute to reset the device
configuration to the default setting.
There are three types of Master Reset:
Cold Start - Reset the device to a default configuration. The device address is
not changed.
Warm Start - Restart the device. This reset function acts just like a power
cycle. None of the configuration parameters are changed.
Reset Address - This reset changes the bus address of the device to the
default address of 126. This change happens immediately regardless of the
state of data exchange the transmitter is in.

ADVANCED
CONFIGURATION
In addition to the basic configuration options and the diagnostic information
and controls, the 8732 has many advanced functions that can also be
configured as required by the application.
DETAILED SETUP
The detailed setup function provides access to other parameters within the
transmitter that can be configured such as coil drive frequency, output
parameters, local display configuration, and other general information about
the device.
Additional Parameters
The additional parameters menu provides a means to configure optional
parameters within the 8732E transmitter.
Density Value
The density value is used to convert from a volumetric flow rate to a mass flow
rate using the following equation:
Qm = Qv 
Where:
Qm is the mass flow rate
Qv is the volumetric flow rate, and
 is the fluid density
NOTE
A density value is required to configure the flow units for mass flow rate
measurement.
Sensor Range: High
This parameter is the maximum value that the PV Range value can be set to.
This is the upper measuring limit of the transmitter and sensor.
Sensor Range: Low
This parameter is the minimum value that the PV Range value can be set to.
This is the lower measuring limit of the transmitter and sensor.
Measurement Mode
Enable or disable the transmitter’s ability to read reverse flow.
Measurement Mode allows the transmitter to read negative flow. This may
occur when flow in the pipe is going the negative direction, or when either
electrode wires or coil wires are reversed. This also enables the totalizer to
count in the reverse direction.

Signal Processing
Rosemount 8732
The 8732E contains several advanced functions that can be used to stabilize
erratic outputs caused by process noise. The signal processing menu
contains this functionality. Below is sample PDM screen shot of Signal
Processing.
Operating Mode (Operation)
The Operating Mode should be used only when the signal is noisy and gives
an unstable output. Filter mode automatically uses 37 Hz coil drive mode and
activates signal processing at the factory set default values. When using filter
mode, perform an auto zero with no flow and a full sensor. Either of the
parameters, coil drive mode or signal processing, may still be changed
individually. Turning Signal Processing off or changing the coil drive frequency
to 5 Hz will automatically change the Operating Mode from filter mode to
normal mode.
SP Control
When ON is selected, the Rosemount 8732E output is derived using a
running average of the individual flow inputs. Signal processing is a software
algorithm that examines the quality of the electrode signal against
user-specified tolerances. This average is updated at the rate of 10 samples
per second with a coil drive frequency of 5 Hz, and 75 samples per second
with a coil drive frequency of 37 Hz. The three parameters that make up
signal processing (number of samples, maximum percent limit, and time limit)
are described below.
Number of Samples
0 to 125 Samples
The number of samples function sets the amount of time that inputs are
collected and used to calculate the average value. Each second is divided
into tenths (1/10) with the number of samples equaling the number of 1/10
second increments used to calculate the average.
For example, a value of:
1 averages the inputs over the past 1/10 second
100 averages the inputs over the past 10 seconds
Percent of Rate
0 to 100 Percent
The maximum percent limit is a tolerance band set up on either side of the
running average. The percentage value refers to deviation from the running
average. For example, if the running average is 100 gal/min, and a 2 percent
maximum limit is selected, then the acceptable range is from 98 to 102
gal/min.
Values within the limit are accepted while values outside the limit are analyzed
to determine if they are a noise spike or an actual flow change.
4-13
Reference Manual
00809-0100-4665, Rev AA
August 2010
Rosemount 8732
Time Limit
0 to 256 Seconds
The time limit parameter forces the output and running average values to the
new value of an actual flow rate change that is outside the percent limit
boundaries. It thereby limits response time to flow changes to the time limit
value rather than the length of the running average.
For example, if the number of samples selected is 100, then the response
time of the system is 10 seconds. In some cases this may be unacceptable.
By setting the time limit, you can force the 8732E to clear the value of the
running average and re-establish the output and average at the new flow rate
once the time limit has elapsed. This parameter limits the response time
added to the loop. A suggested time limit value of two seconds is a good
starting point for most applicable process fluids. The selected signal
processing configuration may be turned ON or OFF to suit your needs.
Coil Drive Frequency
Coil drive frequency allows pulse-rate selection of the sensor coils.
5 Hz
The standard coil drive frequency is 5 Hz, which is sufficient for nearly all
applications.
37 Hz
If the process fluid causes a noisy or unstable output, increase the coil drive
frequency to 37 Hz. If the 37 Hz mode is selected, perform the auto zero
function with no flow and a full sensor.
Low Flow Cutoff
Low flow cutoff allows you to specify the flow rate, between 0.01 and 38.37
feet per second, below which the outputs are driven to zero flow. The units
format for low flow cutoff cannot be changed. It is always displayed as feet per
second regardless of the format selected. The low flow cutoff value applies to
both forward and reverse flows.
Device Info
Information variables are used for identification of flowmeters in the field and
to store information that may be useful in service situations. Information
variables have no effect on flowmeter output or process variables.
Device ID
This function displays the Device ID of the transmitter. This is one piece of
information required to generate a license code to enable diagnostics in the
field.
PV Sensor S/N
The PV sensor serial number is the serial number of the sensor connected to
the transmitter and can be stored in the transmitter configuration for future
reference. The number provides easy identification if the sensor needs
servicing or for other purposes.
Sensor Tag
Sensor tag is the quickest and shortest way of identifying and distinguishing
between sensors. Sensors can be tagged according to the requirements of
your application. The tag may be up to eight characters long.

Explosions could result in death or serious injury:
Installation of this transmitter in an explosive environment must be in accordance with the
appropriate local, national, and international standards, codes, and practices. Please review
the approvals section of the 8732 reference manual for any restrictions associated with a
safe installation.
Electrical shock can result in death or serious injury
Avoid contact with the leads and terminals. High voltage that may be present on leads can
cause electrical shock.
The sensor liner is vulnerable to handling damage. Never place anything through the sensor
for the purpose of lifting or gaining leverage. Liner damage can render the sensor useless.
To avoid possible damage to the sensor liner ends, do not use metallic or spiral-wound
gaskets. If frequent removal is anticipated, take precautions to protect the liner ends. Short
spool pieces attached to the sensor ends are often used for protection.
Correct flange bolt tightening is crucial for proper sensor operation and life. All bolts must be
tightened in the proper sequence to the specified torque limits. Failure to observe these
instructions could result in severe damage to the sensor lining and possible sensor
replacement.
Emerson Process Management can supply lining protectors to prevent liner damage during
removal, installation, and excessive bolt torquing.

SENSOR HANDLING
Rosemount 8732
Handle all parts carefully to prevent damage. Whenever possible, transport
the system to the installation site in the original shipping containers.
PTFE-lined sensors are shipped with end covers that protect it from both
mechanical damage and normal unrestrained distortion. Remove the end
covers just before installation.
Flanged sensors with a lifting lug on each flange make the sensor easier to
handle when it is transported and lowered into place at the installation site.
Flanged sensors that do not have lugs must be supported with a lifting sling
on each side of the housing.
Figure 5-1 shows sensors correctly supported for handling and installation.
Notice the plywood end pieces are still in place to protect the sensor liner
during transportation.

SENSOR MOUNTING
Physical mounting of a sensor is similar to installing a typical section of pipe.
Conventional tools, equipment, and accessories (bolts, gaskets, and
grounding hardware) are required.
Upstream/Downstream
Piping
To ensure specification accuracy over widely varying process conditions,
install the sensor a minimum of five straight pipe diameters upstream and two
pipe diameters downstream from the electrode plane (see Figure 5-2).
Figure 5-2. Upstream and
Downstream
Straight Pipe Diameters
5 Pipe Diameters
2 Pipe Diameters
FLOW
Sensor Orientation
The sensor should be installed in a position that ensures the sensor remains
full during operation. Figures 5-3, 5-4, and 5-5 show the proper sensor
orientation for the most common installations. The following orientations
ensure that the electrodes are in the optimum plane to minimize the effects of
entrapped gas.
Vertical installation allows upward process fluid flow and is generally
preferred. Upward flow keeps the cross-sectional area full, regardless
of flow rate. Orientation of the electrode plane is unimportant in vertical
installations. As illustrated in Figures 5-3 and 5-4, avoid downward flows
where back pressure does not ensure that the sensor remains full at all times.
Installations with reduced straight runs from 0 to five pipe diameters are
possible. In reduced straight pipe run installations, performance will shift to as
much as 0.5% of rate. Reported flow rates will still be highly repeatable.

Horizontal installation should be restricted to low piping sections that are
normally full. Orient the electrode plane to within 45 degrees of horizontal in
horizontal installations. A deviation of more than 45 degrees of horizontal
would place an electrode at or near the top of the sensor thereby making it
more susceptible to insulation by air or entrapped gas at the top of the
sensor.

The electrodes in the Rosemount 8711 are properly oriented when the top of
the sensor is either vertical or horizontal, as shown in Figure 5-6. Avoid any
mounting orientation that positions the top of the sensor at 45 degrees from
the vertical or horizontal position.

INSTALLATION
(FLANGED SENSOR)
The following section should be used as a guide in the installation of the
flange-type Rosemount 8705 and Rosemount 8707 High-Signal Sensors.
Refer to page 5-10 for installation of the wafer-type Rosemount 8711 Sensor.
Gaskets
The sensor requires a gasket at each of its connections to adjacent devices or
piping. The gasket material selected must be compatible with the process fluid and
operating conditions. Metallic or spiral-wound gaskets can damage the
liner. If the gaskets will be removed frequently, protect the liner ends. All other
applications (including sensors with lining protectors or a grounding electrode)
require only one gasket on each end connection, as shown in Figure 5-8. If
grounding rings are used, gaskets are required on each side of the grounding
ring, as shown in Figure 5-9.

Flange Bolts
Suggested torque values by sensor line size and liner type are listed in Table
5-1 on page 5-8 for ASME B16.5 (ANSI) flanges and Table 5-2 and Table 5-3
for DIN flanges. Consult the factory for other flange ratings. Tighten flange
bolts in the incremental sequence as shown in Figure 5-10. See Table 5-1 and
Table 5-2 for bolt sizes and hole diameters.
See ”Safety Messages” on pages 5-1 and 5-2 for complete warning information.

NOTE
Do not bolt one side at a time. Tighten each side simultaneously. Example:
1. Snug left
2. Snug right
3. Tighten left
4. Tighten right
Do not snug and tighten the upstream side and then snug and tighten the
downstream side. Failure to alternate between the upstream and downstream
flanges when tightening bolts may result in liner damage.
Always check for leaks at the flanges after tightening the flange bolts. Failure
to use the correct flange bolt tightening methods can result in severe damage.
All sensors require a second torquing 24 hours after initial flange bolt
tightening.

(1) Derated available with PTFE lining only.
For sensors with ANSI 600# full rated, 900#, 1500#, and 2500# flanges, the
liner is protected from over-compression by the flange design. Standard
flange torque specifications as determined by ANSI and ASME should be
followed. No special precaution is required to prevent liner damage caused by
over torquing. Bolt tightening procedures laid out in this Quick Installation
Guide must still be followed.
To prevent liner damage on any magnetic flowmeter, a flat gasket must be
used. For optimum results on meters with high pressure flanges (ANSI 600#
or above), it is recommended that a flat full face gasket be used.
Under NO circumstances should a spiral wound or flexitallic gasket be used
as this will damage the liner sealing surface.

INSTALLATION
(WAFER SENSOR)
The following section should be used as a guide in the installation of the
Rosemount 8711 Sensor. Refer to page 5-7 for installation of the flange-type
Rosemount 8705 and 8707 High-Signal sensor.
Gaskets
The sensor requires a gasket at each of its connections to adjacent devices or
piping. The gasket material selected must be compatible with the process
fluid and operating conditions. Metallic or spiral-wound gaskets can
damage the liner. If the gaskets will be removed frequently, protect the
liner ends. If grounding rings are used, a gasket is required on each side of
the grounding ring.
Alignment and Bolting
5-10
1.
On 11/2 - through 8-inch (40 through 200 mm) line sizes, place
centering rings over each end of the sensor. The smaller line sizes,
0.15- through 1-inch (4 through 25 mm), do not require centering
rings.
2.
Insert studs for the bottom side of the sensor between the pipe
flanges. Stud specifications are listed in Table 5-4. Using carbon
steel bolts on smaller line sizes, 0.15- through 1-inch
(4 through 25 mm), rather than the required stainless steel bolts,
will degrade performance.

GROUNDING
5-12
Process grounding the sensor is one of the most important details of sensor
installation. Proper process grounding ensures that the transmitter amplifier is
referenced to the process. This creates the lowest noise environment for the
transmitter to make a stable reading. Use Table 5-6 to determine which
grounding option to follow for proper installation.
Reference Manual
00809-0100-4665, Rev AA
August 2010
Rosemount 8732
NOTE
Consult factory for installations requiring cathodic protection or situations
where there are high currents or high potential in the process.
The sensor case should always be earth grounded in accordance with
national and local electrical codes. Failure to do so may impair the protection
provided by the equipment. The most effective grounding method is direct
connection from the sensor to earth ground with minimal impedance.
The Internal Ground Connection (Protective Ground Connection) located in
side the junction box is the Internal Ground Connection screw. This screw is
identified by the ground symbol:

Rosemount 8732
PROCESS LEAK
PROTECTION
(OPTIONAL)
The Rosemount 8705 and 8707 High-Signal Sensor housing is fabricated
from carbon steel to perform two separate functions. First, it provides
shielding for the sensor magnetics so that external disturbances cannot
interfere with the magnetic field and thus affect the flow measurement.
Second, it provides the physical protection to the coils and other internal
components from contamination and physical damage that might occur in an
industrial environment. The housing is completely welded and gasket-free.
The three housing configurations are identified by the W0, W1, or W3 in the
model number option code when ordering. Below are brief descriptions of
each housing configuration, which are followed by a more detailed overview.
Standard Housing
Configuration
•
Code W0 — sealed, welded coil housing (standard configuration)
•
Code W1 — sealed, welded coil housing with a relief valve capable of
venting fugitive emissions to a safe location (additional plumbing from
the sensor to a safe area, installed by the user, is required to vent
properly)
•
Code W3 — sealed, welded coil housing with separate electrode
compartments capable of venting fugitive emissions (additional
plumbing from the sensor to a safe area, installed by the user, is
required to vent properly)
The standard housing configuration is identified by a code W0 in the model
number. This configuration does not provide separate electrode
compartments with external electrode access. In the event of a process leak,
these models will not protect the coils or other sensitive areas around the
sensor from exposure to the pressure fluid (Figure 5-17).

Relief Valves
Rosemount 8732
The first optional configuration, identified by the W1 in the model number
option code, uses a completely welded coil housing. This configuration does
not provide separate electrode compartments with external electrode access.
This optional housing configuration provides a relief valve in the housing to
prevent possible overpressuring caused by damage to the lining or other
situations that might allow process pressure to enter the housing. The relief
valve will vent when the pressure inside the sensor housing exceeds 5 psi.
Additional piping (provided by the user) may be connected to this relief valve
to drain any process leakage to safe containment (see Figure 5-18).

Process Leak
Containment
The second optional configuration, identified as option code W3 in the model
number, divides the coil housing into three compartments: one for each
electrode and one for the coils. Should a damaged liner or electrode fault
allow process fluid to migrate behind the electrode seals, the fluid is contained
in the electrode compartment. The sealed electrode compartment prevents
the process fluid from entering the coil compartment where it would damage
the coils and other internal components.
The electrode compartments are designed to contain the process fluid at full
line pressure. An o-ring sealed cover provides access to each of the electrode
compartments from outside the sensor; drainports are provided in each cover
for the removal of fluid.
NOTE
The electrode compartment could contain full line pressure and it must be
depressurized before the cover is removed.

This section covers basic transmitter and sensor troubleshooting. Problems in
the magnetic flowmeter system are usually indicated by incorrect output
readings from the system, error messages, or failed tests. Consider all
sources when identifying a problem in your system. If the problem persists,
consult your local Rosemount representative to determine if the material
should be returned to the factory. Emerson Process Management offers
several diagnostics that aid in the troubleshooting process.
Instructions and procedures in this section may require special precautions to
ensure the safety of the personnel performing the operations. Please read the
following safety messages before performing any operation described in this
section. Refer to these warnings when appropriate throughout this section.
SAFETY INFORMATION
Failure to follow these installation guidelines could result in death or serious injury:
Installation and servicing instructions are for use by qualified personnel only. Do not perform
any servicing other than that contained in the operating instructions, unless qualified. Verify
that the operating environment of the sensor and transmitter is consistent with the
appropriate FM or CSA approval.
Do not connect a Rosemount 8732 to a non-Rosemount sensor that is located in an
explosive atmosphere.
Mishandling products exposed to a hazardous substance may result in death or serious
injury. If the product being returned was exposed to a hazardous substance as defined by
OSHA, a copy of the required Material Safety Data Sheet (MSDS) for each hazardous
substance identified must be included with the returned goods.
The 8732 performs self diagnostics on the entire magnetic flowmeter system:
the transmitter, the sensor, and the interconnecting wiring. By sequentially
troubleshooting each individual piece of the magmeter system, it becomes
easier to pin point the problem and make the appropriate adjustments.
If there are problems with a new magmeter installation, see “Installation
Check and Guide” on page 6-2 for a quick guide to solve the most common
installation problems. For existing magmeter installations, Table 6-4 lists the
most common magmeter problems and corrective actions.

INSTALLATION CHECK
AND GUIDE
Use this guide to check new installations of Rosemount magnetic flowmeter
systems that appear to malfunction.
Before You Begin
Transmitter
Apply power to your system before making the following transmitter checks.
1.
Verify that the correct sensor calibration number is entered in the
transmitter. The calibration number is listed on the sensor nameplate.
2.
Verify that the correct sensor line size is entered in the transmitter.
The line size value is listed on the sensor nameplate.
3.
Verify that the function blocks are not in Out of Service mode.
4.
Verify that the transmitter is functioning correctly by using the 8714i
Meter Verification diagnostic or the 8714D Calibration Reference
Standard.
Sensor
Be sure that power to your system is removed before beginning sensor
checks.
1.
For horizontal flow installations, ensure that the electrodes remain
covered by process fluid.
For vertical or inclined installations, ensure that the process fluid
is flowing up into the sensor to keep the electrodes covered by
process fluid.
2.
Ensure that the grounding straps on the sensor are connected to
grounding rings, lining protectors, or the adjacent pipe flanges.
Improper grounding will cause erratic operation of the system.
Wiring for Remote Configurations
1.
The signal wire and coil drive wire must be twisted shielded cable.
Emerson Process Management, Rosemount division. recommends
20 AWG twisted shielded cable for the electrodes and 14 AWG
twisted shielded cable for the coils.
2.
The cable shield must be connected at both ends of the electrode and
coil drive cables. Connection of the signal wire shield at both ends is
necessary for proper operation. It is recommended that the coil drive
wire shield also be connected at both ends for maximum flowmeter
performance
3.
The signal and coil drive wires must be separate cables, unless
Emerson Process Management specified combo cable is used. See
Table 2-2 on page 2-11.
4.
The single conduit that houses both the signal and coil drive cables
should not contain any other wires.
Process Fluid
6-2
1.
The process fluid conductivity should be 5 microsiemens
(5 micro mhos) per centimeter minimum.
2.
The process fluid must be free of air and gasses.
3.
The sensor should be full of process fluid.

Rosemount 8732
QUICK
TROUBLESHOOTING
Step 1: Wiring Errors
The most common magmeter problem is wiring between the sensor and the
transmitter in remote mount installations. The signal wire and coil drive wire
must be twisted shielded cable: 20 AWG twisted shielded cable for the
electrodes and 14 AWG twisted shielded cable for the coils. Ensure that the
cable shield is connected at both ends of the electrode and coil drive cables.
Signal and coil drive wires must have their own cables. The single conduit that
houses both the signal and coil drive cables should not contain any other
wires. For more information on proper wiring practices, refer to “Transmitter to
Sensor Wiring” on page 2-11.
Step 2: Process Noise
In some circumstances, process conditions rather than the magmeter can
cause the meter output to be unstable. Possible solutions for addressing a
noisy process situation are given below. When the output attains the desired
stability, no further steps are required.
Use the Auto Zero function to initialize the transmitter for use with the 37.5 Hz
coil drive mode only. Run this function only with the transmitter and sensor
installed in the process. The sensor must be filled with process fluid with zero
flow rate. Before running the auto zero function, be sure the coil drive mode is
set to 37.5 Hz.
Set the loop to manual if necessary and begin the auto zero procedure. The
transmitter completes the procedure automatically in about 90 seconds. A
symbol appears in the lower right-hand corner of the display to indicate that
the procedure is running.
1.
Change the coil drive to 37.5 Hz. Complete the Auto Zero function, if
possible (see “Coil Drive Frequency” on page 4-13).
2.
Turn on Digital Signal Processing (see “Signal Processing” on
page 4-25)
3.
Increase the damping (see “Damping” on page 3-17).
If the preceding steps fail to resolve the process noise symptoms, consult
your Rosemount sales representative about using a high-signal magnetic
flowmeter system.
Step 3: Installed Sensor
Tests
If a problem with an installed sensor is identified, Table 6-5 can assist in
troubleshooting the sensor. Before performing any of the sensor tests,
disconnect or turn off power to the transmitter. To interpret the results, the
hazardous location certification for the sensor must be known. Applicable
codes for the Rosemount 8705 are N0, N5, and KD. Applicable codes for the
Rosemount 8707 are N0 and N5. Applicable codes for the Rosemount 8711
are N0, N5, E5, and KD. Always check the operation of test equipment before
each test.
If possible, take all readings from inside the sensor junction box. If the sensor
junction box is inaccessible, take measurements as close as possible.
Readings taken at the terminals of remote-mount transmitters that are more
than 100 feet away from the sensor may provide incorrect or inconclusive
information and should be avoided. A sensor circuit diagram is provided in
Figure 6-1 on page 6-9.

Profibus PA Function
Blocks
Rosemount 8732
Physical Block - Slot 0
The Physical Block contains physical transmitter information, including
available memory, manufacturer identification, device type, software tag, and
unique identification.
Transducer Block - Slot 5
The transducer block calculates flow from the measured induced voltage and
provides the flowrate input to the AI Block. The calculation includes
information related to the calibration number, line size, and diagnostics.
Analog Input Block - Slot 1
The AI function block processes the measurement and makes it available to
the Host system. The AI function block also allows filtering, alarming, and
engineering unit changes. The 8732E Transmitter with Profibus PA digital
fieldbus comes standard with one AI function block which is dedicated to flow.
Totalizer Block (3 blocks) - Slots, 2, 3, 4
The Totalizer function block allows for totalization of the flow signal. The
8732E Transmitter with Profibus PA digital fieldbus comes with 3 independent
totalizer blocks. Each totalized value can be displayed on the Local Operator
Interface of the device in addition to the Primary Variable.
Sensor Compensation
Rosemount sensors are flow-calibrated and assigned a calibration factor at
the factory. The calibration factor is entered into the transmitter, enabling
interchangeability of sensors without calculations or a compromise in
standard accuracy.
8732E transmitters and other manufacturers’ sensors can be calibrated at
known process conditions or at the Rosemount NIST-Traceable Flow Facility.
Transmitters calibrated on site require a two-step procedure to match a
known flow rate. This procedure can be found in the Operations Manual:

LICENSING AND
ENABLING
All non-basic diagnostics must be licensed by ordering option code D01, D02,
or both. In the event that a diagnostic option is not ordered, advanced
diagnostics can be licensed in the field through the use of a license key. To
obtain a license key, contact your local Rosemount Representative. Each
transmitter has a unique license key specific to the diagnostic option code.
See the detailed procedures below for entering the license key and enabling
the advanced diagnostics.
Licensing the 8732
Diagnostics
For licensing the advanced diagnostics, follow the steps below.
TUNABLE EMPTY PIPE
DETECTION
1.
Power-up the 8732 transmitter
2.
Verify that you have 1.01.001 software or later
3.
Determine the Device ID
4.
Obtain a License Key from your local Rosemount Representative.
5.
Enter License Key
6.
Enable Advanced Diagnostics
The Tunable Empty Pipe detection provides a means of minimizing issues
and false readings when the pipe is empty. This is most important in batching
applications where the pipe may run empty with some regularity.
If the pipe is empty, this diagnostic will activate, set the flow rate to 0, and
deliver a PlantWeb alert.
Turning Empty Pipe On/Of
The Empty Pipe diagnostic can be turned on or off as required by the
application. If the advanced diagnostics suite 1 (D01 Option) was ordered,
then the Empty Pipe diagnostic will be turned on. If D01 was not ordered, the
default setting is off.
Tunable Empty Pipe
Parameters
The Tunable Empty Pipe diagnostic has one read-only parameter, and two
parameters that can be custom configured to optimize the diagnostic
performance.
Empty Pipe Value
Reads the current Empty Pipe Value. This is a read-only value. This number
is a unitless number and is calculated based on multiple installation and
process variables such as sensor type, line size, process fluid properties, and
wiring. If the Empty Pipe Value exceeds the Empty Pipe Trigger Level for a
specified number of updates, then the Empty Pipe diagnostic alert will
activate.

Reference Manual
00809-0100-4665, Rev AA
August 2010
Rosemount 8732
Empty Pipe Trigger Level
Limits: 3 to 2000
This value configures the threshold limit that the Empty Pipe Value must
exceed before the Empty Pipe diagnostic alert activates. The default setting
from the factory is 100.
Empty Pipe Trigger Count
Limits: 5 to 50
This value configures the number of consecutive updates that the Empty Pipe
Value must exceed the Empty Pipe Trigger Level before the Empty Pipe
diagnostic alert activates. The default setting from the factory is 5.
Optimizing Tunable
Empty Pipe
The Tunable Empty Pipe diagnostic is set at the factory to properly diagnose
most applications. If this diagnostic unexpectedly activates, the following
procedure can be followed to optimize the Empty Pipe diagnostic for the
application.
1.
Record the Empty Pipe Value with a full pipe condition.
Example
Full reading = 0.2
2.
Record the Empty Pipe Value with an empty pipe condition.
Example
Empty reading = 80.0
3.
Set the Empty Pipe Trigger Level to a value between the full and
empty readings. For increased sensitivity to empty pipe conditions,
set the trigger level to a value closer to the full pipe value.
Example
Set the trigger level to 25.0
4.
Set the Empty Pipe Counts to a value corresponding to the desired
sensitivity level for the diagnostic. For applications with entrained air
or potential air slugs, less sensitivity may be desired.
Example
Set the counts to 10

Troubleshooting Empty
Pipe
GROUND/WIRING FAULT
DETECTION
The following actions can be taken if Empty Pipe detection is unexpected.
1.
Verify the sensor is full.
2.
Verify that the sensor has not been installed with a measurement
electrode at the top of the pipe.
3.
Decrease the sensitivity by setting the Empty Pipe Trigger Level to a
value above the Empty Pipe Value read with a full pipe.
4.
Decrease the sensitivity by increasing the Empty Pipe Counts to
compensate for process noise. The Empty Pipe Counts is the number
of consecutive Empty Pipe Value readings above the Empty Pipe
Trigger Level required to activate the Empty Pipe alert. The count
range is 5-50, with factory default set at 5.
5.
Increase process fluid conductivity above 50 microsiemens/cm.
6.
Properly connect the wiring between the sensor and the transmitter.
Corresponding terminal block numbers in the sensor and transmitter
must be connected.
7.
Perform the sensor electrical resistance tests. Confirm the resistance
reading between coil ground (ground symbol) and coil (1 and 2) is
infinity, or open. Confirm the resistance reading between electrode
ground (17) and an electrode (18 or 19) is greater than 2 kohms and
rises. For more detailed information, consult Table 6-5 on page 6-8.
The Ground/Wiring Fault Detection diagnostic provides a means of verifying
installations are done correctly. If the installation is not wired or grounded
properly, this diagnostic will activate and deliver a PlantWeb alert. This
diagnostic can also detect if the grounding is lost over-time due to corrosion or
another root cause.
Turning Ground/Wiring Fault On/Of
The Ground/Wiring Fault diagnostic can be turned on or off as required by the
application. If the advanced diagnostics suite 1 (D01 Option) was ordered,
then the Ground/Wiring Fault diagnostic will be turned on. If D01 was not
ordered or licensed, this diagnostic is not available.
Ground/Wiring Fault
Parameters
The Ground/Wiring Fault diagnostic has one read-only parameter. It does not
have any configurable parameters.
Line Noise
Reads the current amplitude of the Line Noise. This is a read-only value. This
number is a measure of the signal strength at 50/60 Hz. If the Line Noise
value exceeds 5 mV, then the Ground/Wiring Fault diagnostic alert will
activate.

Troubleshooting
Ground/Wiring Fault
Rosemount 8732
The transmitter detected high levels of 50/60 Hz noise caused by improper
wiring or poor process grounding.
1.
Verify that the transmitter is earth grounded.
2.
Connect ground rings, grounding electrode, lining protector, or
grounding straps. Grounding diagrams can be found in “Grounding”
on page 5-12.
3.
Verify sensor is full.
4.
Verify wiring between sensor and transmitter is prepared properly.
Shielding should be stripped back less than 1 in. (25 mm).
5.
Use separate shielded twisted pairs for wiring between sensor and
transmitter.
6.
Properly connect the wiring between the sensor and the transmitter.
Corresponding terminal block numbers in the sensor and transmitter
must be connected.
Ground/Wiring Fault
Functionality
The transmitter continuously monitors signal amplitudes over a wide range of
frequencies. For the Ground/Wiring Fault diagnostic, the transmitter
specifically looks at the signal amplitude at frequencies of 50 Hz and 60 Hz
which are the common AC cycle frequencies found throughout the world. If
the amplitude of the signal at either of these frequencies exceeds 5 mV, that is
an indication that there is a ground or wiring issue and that stray electrical
signals are getting into the transmitter. The diagnostic alert will activate
indicating that the ground and wiring of the installation should be carefully
reviewed.
HIGH PROCESS NOISE
DETECTION
The High Process Noise diagnostic detects if there is a process condition
causing unstable or noisy readings, but the noise is not real flow variation.
One common cause of high process noise is slurry flow, like pulp stock or
mining slurries. Other conditions that cause this diagnostic to activate are high
levels of chemical reaction or entrained gas in the liquid. If unusual noise or
variation is seen, this diagnostic will activate and deliver a PlantWeb alert. If
this situation exists and is left without remedy, it will add additional uncertainty
and noise to the flow reading.
Turning High Process Noise On/Off
The High Process Noise diagnostic can be turned on or off as required by the
application. If the advanced diagnostics suite 1 (D01 Option) was ordered,
then the High Process Noise diagnostic will be turned on. If D01 was not
ordered or licensed, this diagnostic is not available.

High Process Noise
Parameters
The High Process Noise diagnostic has two read-only parameters. It does not
have any configurable parameters. This diagnostic requires that flow be
present in the pipe and the velocity be > 1 ft/s.
5 Hz Signal to Noise Ratio
Reads the current value of the signal to noise ratio at the coil drive frequency
of 5 Hz. This is a read-only value. This number is a measure of the signal
strength at 5 Hz relative to the amount of process noise. If the transmitter is
operating in 5 Hz mode, and the signal to noise ratio remains below 25 for
approximately one minute, then the High Process Noise diagnostic alert will
activate.
37 Hz Signal to Noise Ratio
Reads the current value of the signal to noise ratio at the coil drive frequency
of 37 Hz. This is a read-only value. This number is a measure of the signal
strength at 37 Hz relative to the amount of process noise. If the transmitter is
operating in 37 Hz mode, and the signal to noise ratio remains below 25 for
approximately one minute, then the High Process Noise diagnostic alert will
activate.
Troubleshooting High
Process Noise
The transmitter detected high levels of process noise. If the signal to noise
ratio is less than 25 while operating in 5 Hz mode, proceed with the following
steps:
1.
Increase transmitter coil drive frequency to 37 Hz (refer to “Coil Drive
Frequency” on page 4-13) and, if possible, perform Auto Zero
function (refer to “Auto Zero” on page 4-12).
2.
Verify sensor is electrically connected to the process with grounding
electrode, grounding rings with grounding straps, or lining protector
with grounding straps.
3.
If possible, redirect chemical additions downstream of the magmeter.
4.
Verify process fluid conductivity is above 10 microsiemens/cm.
If the signal to noise ratio is less than 25 while operating in 37 Hz mode,
proceed with the following steps:
C-6
1.
Turn on the Digital Signal Processing (DSP) technology and follow
the setup procedure (refer to Appendix D: Digital Signal Processing).
This will minimize the level of damping in the flow measurement and
control loop while also stabilizing the reading to minimize valve
actuation.
2.
Increase damping to stabilize the signal (refer to “PV Damping” on
page 3-11). This will add dead-time to the control loop.
3.
Move to a Rosemount High-Signal flowmeter system. This flowmeter
will deliver a stable signal by increasing the amplitude of the flow
signal by ten times to increase the signal to noise ratio. For example if
the signal to noise ratio (SNR) of a standard magmeter is 5, the
High-Signal would have a SNR of 50 in the same application. The
Rosemount High-Signal system is comprised of the 8707 sensor
which has modified coils and magnetics and the 8712H High-Signal
transmitter.
Reference Manual

Rosemount 8732
NOTE
In applications where very high levels of noise are a concern, it is
recommended that a dual-calibrated Rosemount High-Signal 8707 sensor be
used. These sensors can be calibrated to run at lower coil drive current
supplied by the standard Rosemount transmitters, but can also be upgraded
by changing to the 8712H High-Signal transmitter.
High Process Noise
Functionality
The High Process Noise diagnostic is useful for detecting situations where the
process fluid may be causing electrical noise resulting in a poor measurement
from the magnetic flowmeter. There are three basic types of process noise
that can affect the performance of the magnetic flowmeter system.
1/f Noise
This type of noise has higher amplitudes at lower frequencies, but generally
degrades over increasing frequencies. Potential sources of 1/f noise include
chemical mixing and the general background noise of the plant.
Spike Noise
This type of noise generally results in a high amplitude signal at specific
frequencies which can vary depending on the source of the noise. Common
sources of spike noise include chemical injections directly upstream of the
flowmeter, hydraulic pumps, and slurry flows with low concentrations of
particles in the stream. The particles bounce off of the electrode generating a
“spike” in the electrode signal. An example of this type of flow stream would
be a recycle flow in a paper mill.
White Noise
This type of noise results in a high amplitude signal that is relatively constant
over the frequency range. Common sources of white noise include chemical
reactions or mixing that occurs as the fluid passes through the flowmeter and
high concentration slurry flows where the particulates are constantly passing
over the electrode head. An example of this type of flow stream would be a
high consistency pulp stock stream (>10%) in a paper mill.
The transmitter continuously monitors signal amplitudes over a wide range of
frequencies. For the high process noise diagnostic, the transmitter specifically
looks at the signal amplitude at frequencies of 2.5 Hz, 7.5 Hz, 32.5 Hz, and
42.5 Hz. The transmitter uses the values from 2.5 and 7.5 Hz and calculates
an average noise level. This average is compared to the amplitude of the
signal at 5 Hz. If the signal amplitude is not 25 times greater than the noise
level, and the coil drive frequency is set at 5 Hz, the High Process Noise alert
will activate indicating that the flow signal may be compromised. The
transmitter performs the same analysis around the 37.5 Hz coil drive
frequency using the 32.5 Hz and 42.5 Hz values to establish a noise level.

8714I METER
VERIFICATION
The 8714i Meter Verification diagnostic provides a means of verifying the
flowmeter is within calibration without removing the sensor from the process.
This is a manually initiated diagnostic test that provides a review of the
transmitter and sensors critical parameters as a means to document
verification of calibration. The results of running this diagnostic provide the
deviation amount from expected values and a pass/fail summary against
user-defined criteria for the application and conditions.
Initiating 8714i Meter Verification
The 8714i Meter Verification diagnostic can be initiated as required by the
application. If the advanced diagnostic suite (D02) was ordered, then the
8714i Meter Verification diagnostic will be available. If D02 was not ordered or
licensed, this diagnostic will not be available.
Sensor Signature
Parameters
The sensor signature describes the magnetic behavior of the sensor. Based
on Faraday’s law, the induced voltage measured on the electrodes is
proportional to the magnetic field strength. Thus, any changes in the magnetic
field will result in a calibration shift of the sensor.
Establishing the baseline sensor signature
The first step in running the 8714i Meter Verification test is establishing the
reference signature that the test will use as the baseline for comparison. This
is accomplished by having the transmitter take a signature of the sensor.
Having the transmitter take an initial sensor signature when first installed will
provide the baseline for the verification tests that are done in the future. The
sensor signature should be taken during the start-up process when the
transmitter is first connected to the sensor, with a full line, and ideally with no
flow in the line. Running the sensor signature procedure when there is flow in
the line is permissible, but this may introduce some noise into the signature
measurements. If an empty pipe condition exists, then the sensor signature
should only be run for the coils.
Once the sensor signature process is complete, the measurements taken
during this procedure are stored in non-volatile memory to prevent loss in the
event of a power interruption to the meter.
8714i Meter Verification
Test Scope
The 8714i Meter Verification can be used to verify the entire flowmeter
installation, or individual parts such as the transmitter or sensor. This
parameter is set at the time that the 8714i Meter Verification test is initiated.
All
Run the 8714i Meter Verification test and verify the entire flowmeter
installation. This parameter results in the verification test performing the
transmitter calibration verification, sensor calibration verification, coil health
check, and electrode health check. Transmitter calibration and sensor
calibration are verified to the percentage associated with the test condition
selected when the test was initiated.
Flowtube Sensor
Run the 8714i Meter Verification test on the sensor only. This results in the
verification test checking the sensor calibration to the limits of the test criteria
selected when the 8714i Meter Verification test was initiated, verifying the coil
circuit health, and the electrode circuit health.

the verification test only checking the transmitter calibration to the limits of the
test criteria selected when the 8714i Meter Verification test was initiated.
8714i Meter Verification
Test Parameters
The 8714i has a multitude of parameters that set the test criteria, test
conditions, and scope of the calibration verification test.
Test Conditions for the 8714i Meter Verification
There are three possible test conditions that the 8714i Meter Verification test
can be initiated under. This parameter is set at the time that the Sensor
Signature or 8714i Meter Verification test is initiated.
No Flow, Full Pipe
Run the 8714i Meter Verification test with a full pipe and no flow in the line.
Running the 8714i Meter Verification test under this condition provides the
most accurate results and the best indication of magnetic flowmeter health.
Flowing, Full Pipe
Run the 8714i Meter Verification test with a full pipe and flow in the line.
Running the 8714i Meter Verification test under this condition provides the
ability to verify the magnetic flowmeter health without shutting down the
process flow in applications where a shutdown is not possible. Running the
calibration verification under flowing conditions can cause false fails if the flow
rate is not at a steady flow, or if there is process noise present.
Empty Pipe
Run the 8714i Meter Verification test with an empty pipe. Running the 8714i
Meter Verification test under this condition provides the ability to verify the
magnetic flowmeter health with an empty pipe. Running the calibration
verification under empty pipe conditions will not check the electrode circuit
health.
8714i Meter Verification Test Criteria
The 8714i Meter Verification diagnostic provides the ability for the user to
define the test criteria that the verification must test to. The test criteria can be
set for each of the flow conditions discussed above.
No Flow, Full Pipe
Set the test criteria for the No Flow condition. The factory default for this value
is set to two percent with limits configurable between one and ten percent.
Flowing, Full Pipe
Set the test criteria for the Flowing, Full condition. The factory default for this
value is set to three percent with limits configurable between one and ten
percent
Empty Pipe
Set the test criteria for the Empty Pipe condition. The factory default for this
value is set to three percent with limits configurable between one and ten
percent

8714i Meter Verification
Test Results Parameters
Once the 8714i Meter Verification test is initiated, the transmitter will make
several measurements to verify the transmitter calibration, sensor calibration,
coil circuit health, and electrode circuit health. The results of these tests can
be reviewed and recorded on the calibration verification report found on
page C-14. This report can be used to validate that the meter is within the
required calibration limits to comply with governmental regulatory agencies
such as the Environmental Protection Agency or Food and Drug
Administration.
Viewing the 8714i Meter Verification Results
Depending on the method used to view the results, they will be displayed in
either a menu structure, as a method, or in the report format. When using the
375 Field Communicator, each individual component can be viewed as a
menu item. In AMS, the calibration report is populated with the necessary
data eliminating the need to manually complete the report found on
page C-14.
The results are displayed in the following order:
Test Condition
Review the test condition that the 8714i Meter Verification test was performed
under.
Test Criteria
Review the test criteria used to determine the results of the 8714i Meter
Verification tests.
8714i Result
Displays the overall result of the 8714i Meter Verification test as either a Pass
or Fail.
Simulated Velocity
Displays the simulated velocity used to verify the transmitter calibration
Actual Velocity
Displays the velocity measured by the transmitter during the transmitter
calibration verification process
Velocity Deviation
Displays the deviation in the actual velocity compared to the simulated
velocity in terms of a percentage. This percentage is then compared to the
test criteria to determine if the transmitter is within calibration limits.
Transmitter Calibration Verification
Displays the results of the transmitter calibration verification test as either a
Pass or Fail
Sensor Calibration Deviation
Displays the deviation in the sensor calibration. This value tells how much the
sensor calibration has shifted from the original baseline signature. This
percentage is compared to the test criteria to determine if the sensor is within
calibration limits.

Optimizing the 8714i
Meter Verification
The 8714i Meter Verification diagnostic can be optimized by setting the test
criteria to the desired levels necessary to meet the compliance requirements
of the application. The following examples below will provide some guidance
on how to set these levels.
Example
An effluent meter must be certified every year to comply with Environmental
Protection Agency and Pollution Control Agency standards. These
governmental agencies require that the meter be certified to five percent
accuracy.
Since this is an effluent meter, shutting down the process may not be viable.
In this instance the 8714i Meter Verification test will be performed under
flowing conditions. Set the test criteria for Flowing, Full to five percent to meet
the requirements of the governmental agencies.
Example
A pharmaceutical company requires semi-annual verification of meter
calibration on a critical feed line for one of their products. This is an internal
standard, but plant requirements require a calibration record be kept on-hand.
Meter calibration on this process must meet one percent. The process is a
batch process so it is possible to perform the calibration verification with the
line full and with no flow.
Since the 8714i Meter Verification test can be run under no flow conditions,
set the test criteria for No Flow to one percent to comply with the necessary
plant standards.
Example
A food and beverage company requires an annual verification of a meter on a
product line. The plant standard calls for the accuracy to be three percent or
better. They manufacture this product in batches, and the measurement
cannot be interrupted when a batch is in process. When the batch is
complete, the line goes empty.
Since there is no means of performing the 8714i Meter Verification test while
there is product in the line, the test must be performed under empty pipe
conditions. The test criteria for Empty Pipe should be set to three percent, and
it should be noted that the electrode circuit health cannot be verified.

In the event that the 8714i Meter Verification test fails, the following steps can
be used to determine the appropriate course of action. Begin by reviewing the
8714i results to determine the specific test that failed.
Potential Causes of Failure
Steps to Correct
Transmitter Verification Test
Failed
Test
• Unstable flow rate during
the verification test
• Noise in the process
• Transmitter drift
• Faulty electronics
• Perform the test with no
flow in the pipe
• Check calibration with an
external standard like the
8714D
• Perform a digital trim
• Replace the electronics
Sensor Verification Failed
• Moisture in the terminal
block of the sensor
• Calibration shift caused by
heat cycling or vibration
• Remove the sensor and
send back for recalibration.
Coil Circuit Health Failed
• Moisture in the terminal
block of the sensor
• Shorted Coil
• Perform the sensor checks
detailed on page 6-8.
Electrode Circuit Health
Failed
• Moisture in the terminal
block of the sensor
• Coated Electrodes
• Shorted Electrodes
• Perform the sensor checks
detailed on page 6-8.
The 8714i Meter Verification diagnostic functions by taking a baseline sensor
signature and then comparing measurements taken during the verification
test to these baseline results.
Sensor Signature Values
The sensor signature describes the magnetic behavior of the sensor. Based
on Faraday’s law, the induced voltage measured on the electrodes is
proportional to the magnetic field strength. Thus, any changes in the magnetic
field will result in a calibration shift of the sensor. Having the transmitter take
an initial sensor signature when first installed will provide the baseline for the
verification tests that are done in the future. There are three specific
measurements that are stored in the transmitter’s non-volatile memory that
are used when performing the calibration verification.
Coil Circuit Resistance
The Coil Circuit Resistance is a measurement of the coil circuit health. This
value is used as a baseline to determine if the coil circuit is still operating
correctly when the 8714i Meter Verification diagnostic is initiated.
Coil Signature
The Coil Signature is a measurement of the magnetic field strength. This
value is used as a baseline to determine if a sensor calibration shift has
occurred when the 8714i Meter Verification diagnostic is initiated
Electrode Circuit Resistance
The Electrode Circuit Resistance is a measurement of the electrode circuit
health. This value is used as a baseline to determine if the electrode circuit is
still operating correctly when the 8714i Meter Verification diagnostic is
initiated.

PROCEDURES
If the output of your Rosemount 8732 is unstable, first check the wiring and
grounding associated with the magnetic flowmeter system. Ensure that the
following conditions are met:
•
Ground straps are attached to the adjacent flange or ground ring?
•
Grounding rings, lining protectors, or grounding electrodes are being
used in lined or nonconductive piping?
•
Both of the shields are attached at both ends?
The causes of unstable transmitter output can usually be traced to extraneous
voltages on the measuring electrodes. This “process noise” can arise from
several causes including electrochemical reactions between the fluid and the
electrode, chemical reactions in the process itself, free ion activity in the fluid,
or some other disturbance of the fluid/electrode capacitive layer. In such noisy
applications, an analysis of the frequency spectrum reveals process noise
that typically becomes significant below 15 Hz.
In some cases, the effects of process noise may be sharply reduced by
elevating the coil drive frequency above the 15 Hz region. The Rosemount
8732 coil drive mode is selectable between the standard 5 Hz and the
noise-reducing 37 Hz. See “Coil Drive Frequency” on page 4-26 for
instructions on how to change the coil drive mode to 37 Hz.
Auto Zero
To ensure optimum accuracy when using 37 Hz coil drive mode, there is an
auto zero function that must be initiated during start-up. The auto zero
operation is also discussed in the start-up and configuration sections. When
using 37 Hz coil drive mode it is important to zero the system for the specific
application and installation.
The auto zero procedure should be performed only under
the following conditions:
•
With the transmitter and sensor installed in their final positions. This
procedure is not applicable on the bench.
•
With the transmitter in 37 Hz coil drive mode. Never attempt this
procedure with the transmitter in 5 Hz coil drive mode.
•
With the sensor full of process fluid at zero flow.
These conditions should cause an output equivalent to zero flow.
Signal Processing
If the 37 Hz coil drive mode has been set, and the output is still unstable, the
damping and signal processing function should be used. It is important to set
the coil drive mode to 37 Hz first, so the loop response time is not increased.
The 8732 provides for a very easy and straightforward start-up, and also
incorporates the capability to deal with difficult applications that have
previously manifested themselves in a noisy output signal. In addition to
selecting a higher coil drive frequency (37 Hz vs. 5 Hz) to isolate the flow
signal from the process noise, the 8732 microprocessor can actually
scrutinize each input based on three user-defined parameters to reject the
noise specific to the application.

Reference Manual

August 2010
Rosemount 8732
This software technique, known as signal processing, “qualifies” individual
flow signals based on historic flow information and three user-definable
parameters, plus an on/off control. These parameters are:
1.
Number of samples: The number of samples function sets the amount
of time that inputs are collected and used to calculate the average
value. Each second is divided into tenths (1/10 ) with the number of
samples equaling the number of 1/10 second increments used to
calculate the average. Factory Preset Value = 90 samples.
For example, a value of:
1 averages the inputs over the past 1/10 second
10 averages the inputs over the past 1 second
100 averages the inputs over the past 10 seconds
125 averages the inputs over the past 12.5 seconds
2.
Maximum Percent Limit: The tolerance band set up on either side of
the running average, referring to percent deviation from the average.
Values within the limit are accepted while value outside the limit are
scrutinized to determine if they are a noise spike or an actual flow
change. Factory Preset Value = 2 percent.
3.
Time Limit: Forces the output and running average values to the new
value of an actual flow rate change that is outside the percent limit
boundaries, thereby limiting response time to real flow changes to the
time limit value rather than the length of the running average. Factory
Preset Value = 2 seconds.
How Does It Really Work?
The best way to explain this is with the help of an example, plotting flow rate
versus time

x:
o:
Input flow signal from sensor.
Average flow signals and transmitter output, determined by the “number
of samples” parameter.
Tolerance band, determined by the “percent limit” parameter.
– Upper value = average flow + [(percent limit/100) average flow]
– Lower value = average flow – [(percent limit/100) average flow]
1.
This scenario is that of a typical non-noisy flow. The input flow signal
is within the percent limit tolerance band, therefore qualifying itself as
a good input. In this case the new input is added directly into the
running average and is passed on as a part of the average value to
the output.
2.
This signal is outside the tolerance band and therefore is held in
memory until the next input can be evaluated. The running average is
provided as the output.
3.
The previous signal currently held in memory is simply rejected as a
noise spike since the next flow input signal is back within the
tolerance band. This results in complete rejection of noise spikes
rather than allowing them to be “averaged” with the good signals as
occurs in the typical analog damping circuits.
4.
As in number 2 above, the input is outside the tolerance band. This
first signal is held in memory and compared to the next signal. The
next signal is also outside the tolerance band (in the same direction),
so the stored value is added to the running average as the next input
and the running average begins to slowly approach the new input
level.
5.
To avoid waiting for the slowly incrementing average value to catch
up to the new level input, a shortcut is provided. This is the “time limit”
parameter. The user can set this parameter to eliminate the slow
ramping of the output toward the new input level.
When Should Signal Processing Be Used?
The Rosemount 8732 offers three separate functions that can be used in
series for improving a noisy output. The first step is to toggle the coil drive to
the 37 Hz mode and initialize with an auto zero. If the output is still noisy at
this stage, signal processing should be actuated and, if necessary, tuned to
match the specific application. Finally, if the signal is still too unstable, the
traditional damping function can be used.
NOTE
Failure to complete an Auto Zero will result in a small (<1%) error in the
output. While the output level will be offset by the error, the repeatability will
not be affected.

Connecting Sensors of
Other Manufacturers
Rosemount 8732
Before connecting another manufacturer’s sensor to the Rosemount 8732
transmitter, it is necessary to perform the following functions.
1.
Turn off the AC power to the sensor and transmitter. Failure to do so
could result in electrical shock or damage to the transmitter.
2.
Verify that the coil drive cables between the sensor and the
transmitter are not connected to any other equipment.
3.
Label the coil drive cables and electrode cables for connection to the
transmitter.
4.
Disconnect the wires from the existing transmitter.
5.
Remove the existing transmitter. Mount the new transmitter. See
“Mount the Transmitter” on page 2-3.
6.
Verify that the sensor coil is configured for series connection. Other
manufacturers sensors may be wired in either a series or parallel
circuit. All Rosemount magnetic sensors are wired in a series circuit.
(Other manufacturers AC sensors (AC coils) wired for 220V operation
are typically wired in parallel and must be rewired in series.)
7.
Verify that the sensor is in good working condition. Use the
manufacturer’s recommended test procedure for verification of
sensor condition. Perform the basic checks:
a. Check the coils for shorts or open circuits.
b. Check the sensor liner for wear or damage.
c. Check the electrodes for shorts, leaks, or damage.
8.
Connect the sensor to the transmitter in accordance with reference
wiring diagrams. See Appendix E: Universal Sensor Wiring Diagrams
for specific drawings.
9.
Connect and verify all connections between the sensor and the
transmitter, then apply power to the transmitter.
10. Perform the Universal Auto Trim function.
This is a pulsed DC magnetic flowmeter. Do not connect
AC power to the sensor or to terminals 1 and 2 of the
transmitter, or replacement of the electronics board will be

Identify the Terminals
First check the sensor manufacturer’s manual to identify the appropriate
terminals. Otherwise, perform the following procedure.
Identify coil and electrode terminals
1.
Select a terminal and touch an ohmmeter probe to it.
2.
Touch the second probe to each of the other terminals and record the
results for each terminal.
3.
Repeat the process and record the results for every terminal.
Coil terminals will have a resistance of approximately 3-300 ohms.
Electrode terminals will have an open circuit.
Identify a chassis ground
1.
Touch one probe of an ohmmeter to the sensor chassis.
2.
Touch the other probe to the each sensor terminal and the record the
results for each terminal.
The chassis ground will have a resistance value of one ohm or less.
Wiring Connections
Connect the electrode terminals to Rosemount 8732 terminals
18 and 19. The electrode shield should be connected to terminal 17.
Connect the coil terminals to Rosemount 8732 terminals 1, 2, and
.
If the Rosemount 8732 Transmitter indicates a reverse flow condition, switch
the coil wires connected to terminals 1 and 2.
This is a pulsed DC magnetic flowmeter.
Do not connect AC power to the sensor
or to terminals 1 and 2 of the
