Introduction
Principle of Operation
The V-Bar is an insertion vortex flowmeter.
Unlike a full-bore flowmeter, which replaces
a section of pipe, an insertion meter is inserted
into the pipe line through a hole cut into the
pipe wall. When installed with an isolation
valve, a retractable insertion flowmeter can
be installed without process shutdown.

Sensor
FLOW
The V-Bar measures the volumetric flow rate
by measuring the local velocity at the sensor
insertion depth. The local velocity is determined by detecting the frequency at which
vortices are alternately shed from the sensor's bluff body. The vortices pass the sensor
wing, causing a slight deformation in the
wing, which is detected by semiconductor
strain gauges. The strain gauges generate
an electrical frequency signal that is proportional to the local velocity.
The V-Bar's microprocessor-based electronics amplify and filter the sensor input. The
local velocity is converted into an average
velocity and then into an average flow rate in
user-selectable engineering units. The electronics then provide a 4-20 mA and/or frequency output proportional to the flow rate.
Standard local display alternately indicates
flow rate and totalized flow.

Installation
Guidelines
Not all plumbing is laid out with flowmetering in mind. For optimum performance,
you must consider straight run requirements
and the installation site relative to flow direction. Figures 2-1 through 2-5 illustrate
useful examples of both proper and improper
flowmeter installations. If you have special
requirements, please consult the factory.

Figure 2-3. Non-vertical Mounting. If non-vertical
mounting is necessary, the deviation from vertical should
not exceed 90°.
Figure 2-4. Meter Alignment. The flowmeter should be
aligned perpendicular to the pipe to avoid measurement
errors.
Figure 2-2. Meter Location. Recommended meter locations ensure that the pipe will always be filled
with fluid.

to complete the installation.
V-Bar-910/960: Insertion
Depth Calculation
To properly position the sensor within the
pipe, the scale reading must be calculated
(Figures 3-23 and 3-24). The scale reading
is the value to which the cursor should be
pointing on the depth scale. Use the following equation to calculation the scale reading:
Scale Reading = I + E + Wt
Figure 3-22. Cold Tap Installation for V-Bar-910/960
Where:
I = For pipe sizes 10" and smaller,
pipe internal diameter ÷ 2
= For pipe sizes 12" and larger, 5"
MECHANICAL INSTALLATION
Section 3
E = Distance from the raised face of
the flange to the outside pipe wall
Wt = The thickness of the pipe wall
which can be determined by measuring the disk cut out of the
pipe from the tapping procedure.
This number can also be obtained
from a piping handbook.

Example
A V-Bar-910 is to be installed on a 12"
schedule 40 pipe. The following measurements have been obtained:
I = 5"
E = 12.5"
Wt = 0.406"
Scale reading = I + E + Wt
Scale reading = 5" + 12.5" + 0.406" = 17.906"
V-Bar-910/960:
Final Positioning
Loosen the two packing gland nuts on the
stem housing of the meter. (Figure 3-25)
Turn handwheel clockwise to insert the stem
into the pipe. Do so until the calculated scale
reading lines up with the 1.0 arrow on the
retractor bar assembly.
Caution: Do not force stem into pipe. If
the stem insertion is blocked, retract and
remove the meter from the pipe line. Verify that the hole is 1.875 inches in diameter and that the mounting connections
are centered on the hole.

Section 4:
Electrical
Installation
Wiring and conduit must be installed in
accordance with national, local laws, standards, codes, and industry practices to avoid
personal injury or property damage from
electrical shock, contact with live electrical
systems, or ignition of combustible material
or explosive gases, which can be ignited by
electrical arcing.
Hardware Configuration
The flowmeter hardware is factory configured for each specific application. Additional
configuration should not be required unless
your application changes. Jumper position
JP3 selects fluid type. JP3 should be installed
for gas applications and removed for liquid
applications. The installation of jumpers JP1
and JP2 on the filter board control the output
selection. Jumper positions JP1 and JP2 indicate pulse output configuration. JP1 is installed at the factory. These jumpers are
located on the filter board (the base board of
the electronic stack). See figure 4-1.
To configure jumpers, access the filter board,
located in the flow transmitter condulet. To
access the filter board, see Electronics Removal in Section 6: Troubleshooting and
Maintenance.
Mounting Electronics
Electronics can be ordered for either integral
or remote mounting. With integral mounting,
the sensor and electronics are manufactured
as one unit. The ambient temperature must
be less than 140 °F for integral mounting.
Figure 4-1. Filter Board for V-Bar™
ELECTRICAL INSTALLATION
20
Section 4
With remote mounting, the electronics are
manufactured as a unit separate from the
flow sensor. Remote electronics can be
mounted on either a pipe or a wall. The
distance between the sensor and the electronics must not exceed 50 feet (17 meters). If
remote mounting is specified in an order,
EMCO supplies 30 feet of cable and pipe
mounting clamps.
Field Wiring Access
Remove the field wiring condulet cap to
access the field wiring terminal block for
power and signal wiring. (Figure 4-2)
Grounding the Meter
To ensure proper electrical noise rejection,
connect ground strap (size 8 AWG or larger
wire) from the ground screw attached to the
outside of the electronics enclosure to a known
earth ground (not the pipe). (Figure 4-3)
VAC Power Supply
The V-Bar may be operated using a 24 volt
power supply. For proper power and signal
wiring, shielded cable should be at least 18
AWG or larger. Connect shield wire from
shielded cable to earth ground at power supply. Insulate other end of shield wire from
electrical condulet at the meter. (Figure 4-4)

Flowmeter Removal
A functionality test should be performed at
the electronics condulet regardless of mounting configuration (integral or remote). Use
proper ESD precautions at all times. Disconnect the power. Remove the electronics
stack from the condulet and place into an
antistatic bag. Verify the sensor is properly
connected to the filter board. Disconnect the
sensor from the filter board. Insert solid
wire (approximately. 1⁄32" diameter) into the
sensor female connector to serve as leads.
Check the resistance between the red wire
and the green (or white) wire. The resistance
should be between 500 and 2500 Ω. Check
the resistance between the green (or white)
and the black wire. The resistance should be
between 500 and 2500 Ω. The two previous
resistance measurements should be within
30 Ω of each other. Check the resistance
between all four wires and earth ground
(the condulet or meter body). The resistance
should be 20 mΩ or greater. (Figure 6-4)

TEM Wiring
TEM: Zero and Span
Adjustments
The temperature transmitter is factory
prewired to the field wiring terminal block
of the V-Bar. No wiring to the TEM itself
is required. There are four terminals on the
TEM terminal strip:
1&5
Terminals 1 and 5 are the RTD
terminals. The leads from the
RTD are connected to these terminals.
3
Terminal 3 is the supply voltage
terminal. This terminal is connected to terminal 5 of the junction box terminal block.
4
Terminal 4 is the return 4-20 mA
signal. This terminal is connected
to terminal 2 of the junction box
terminal block.
Using a 24 VAC power supply, precision
R-box, and digital multimeter, make the
connections to the TEM as shown in
Figure 6-36. Refer to the TEM calibration
data supplied with the instrument. (A copy is
also inside the condulet). The table below is
an example of this data sheet.
Figure 6-35. TEM Internal Wiring
Calibration Data
4.00 mA: 32 °F = 1000.00W
8.00 mA: 41 °F = 1019.03W
12.0 mA: 50 °F = 1038.04W
16.0 mA: 59 °F = 1057.02W
20.0 mA: 68 °F = 1075.96W
Step 1. Set the R-box to zero scale (4 mA),
according to the resistance value in the calibration data.
Step 2. Turn the zero adjustment potentiometer until the output reads 4 ± 0.016 mA.
Step 3. Set the R-box to full-scale (20 mA),
according to the resistance value on the calibration data.
Step 4. Turn the span adjustment potentiometer until the output reads 20 ± .016 mA.
Step 5. Because the span adjustment affects
the zero point, repeat the steps above until
the zero and span readings are within ± 0.016
of zero and full- scale.

EMCO's model V-Bar™ Insertion Vortex Flowmeters measure flow rates
for a wide variety of fluids and pipe sizes. Unlike an inline flowmeter,
which replaces a section of pipe, an insertion meter is “tapped” into the
flow line and can be mounted virtually anywhere.
EMCO's V-Bar insertion flowmeters have three main components: the
retractor, the sensor, and the electronics. The retractor serves to position the sensor within the pipe. The sensor detects the pattern of
vortices as a frequency signal. The “Smart,” microprocessor-based
EZ-Logic electronics conditions the signal and provides a frequency
output, a scaled pulse output, or a 4–20 mA dc signal proportional to
the average pipe flow rate.
Most V-Bar flowmeters can be installed on an isolation valve, which
permits installation and removal without process shutdown. Integral
pressure and/or temperature measurement may be combined with the
V-Bar to provide mass flow measurement from a single pipe tap. In
addition, a flow processor may be used to increase the accuracy and
functionality of the metering system.

The PT combines micro-machined silicon diaphragms with fully welded
stainless steel and hastelloy pressure ports to provide a highly accurate,
stable pressure transmitter. It is constructed with the materials and
environmental protection required for industrial applications.
The silicon sensors incorporate developments derived from aerospace
applications and use them to decrease output noise, non–linearity, and
hysteresis and to improve long term stability.
A detachable industrial electrical connector provides access to the
independent zero and span trim controls. If any on-site configuration
changes to the electrical or pressure connections are required, replacement parts and screw in pressure adaptors are available.
Each transmitter incorporates RFI/EMC and electrical spike protection.

0.25% of full scale (the best straight line–determined from
the combined effects of non-linearity, hysteresis, and repeatability).
For ranges of 5 psi and above, the output will not deviate from
room temperature calibration by more than:
2.0% full scale over 15 to 122 °F (–9.4 to 50 °C)
3.0% full scale over –5 to 175 °F (–20.6 to 79.4 °C)
Typically:
1.0% full scale over 15 to 122 °F (–9.4 to 50 °C)
2.0% full scale over –5 to 175 °F (–20.6 to 79.4 °C)
For ranges below 5 psi these values will increase pro–rata with
calibrated span.

Model TEM
General Specification
Features
! RTD or
4-20 mA current output
(linear)
! Factory calibrated over
selected range
! Rugged design
! Thermowell included
EMCO's TEM platinum resistance temperature sensors measure process fluid temperature for most applications. The TEM uses a resistance
temperature device (RTD) to measure process temperature. RTDs
operate on the principle that the resistance of the sensing device is
proportional to the temperature, producing a highly repeatable and
exceptionally stable resistance versus temperature relationship.
The TEM may be selected with either a direct RTD output or with an
industry standard 4-20 mA current output. The current output includes
a preamplifier that is factory scaled and calibrated to one of several
standard temperature ranges in either degrees Fahrenheit or Celsius.
The TEM is thermowell mounted to allow installation and removal
without process shutdown. Several immersion lengths are available to
accommodate a wide range of pipe sizes.

Glossary
ac Alternating current; an electric current that reverses direction at regular intervals.
ambient temperature the average or mean temperature of
the surrounding air which comes in contact with the equipment
and instruments in use.
analog output a voltage or current signal that is a continuous
function of the measured parameter (i.e. flow, pressure, temperature).
ANSI American National Standards Institute, the primary organization for fostering the development of technology standards in the United States.
AWG American Wire Gauge; A standard of the dimensional
characteristics of wire used to conduct electrical current or
signals.
°F Degrees Fahrenheit
FM Factory Mutual Research Corporation; An organization
which sets industrial safety standards.
frequency output An oscillating or varying current, where
frequency is the number of complete cycles per second in
alternating current direction. The standard unit of frequency
is the hertz, abbreviated Hz. If a current completes one
cycle per second, then the frequency is 1 Hz; 60 cycles per
second equals 60 Hz (the standard alternating-current utility
frequency). Larger units of frequency include the kilohertz
(kHz) representing thousands (1,000's) of cycles per second,
the megahertz (MHz) representing millions (1,000,000's) of
cycles per second.

viscosity The inherent resistance of a substance to flow.
Ω ohm
output The electrical signal measured at the output terminals
which is produced by an applied input to a transducer.
upstream In flowmetering, the piping from the point of flowmeter that is against the direction of flow.
resistance A measure of the extent to which a substance
opposes the movement of electrons among atoms. The more
easily the atoms give up and/or accept electrons, the lower
the resistance. It is always a positive real-number quantity.
Resistance is observed with ac and dc voltage. The standard
unit of resistance is the ohm, sometimes written out as a
word, and sometimes symbolized by the uppercase Greek
letter omega. When an electric current of one ampere passes
through a component across which a potential difference (voltage) of one volt exists, then the resistance of that component
is one ohm.
weld-o-let A steel fitting that is welded to a pipe to provide
a mounting for equipment which does not have threads and
may require welding.
