ProBar Flowmeter

The following list is a summary of the steps required to complete a
ProBar flowmeter installation. If this is an entirely new installation,
begin with step 1. If the mounting is already in place, verify that the
hole size and the fittings match the recommended specifications, and
begin with step 5.

1. Determine where the ProBar is to be placed within the
piping system.

2. Establish the proper orientation as determined by the intended
ProBar service for the flowmeter.

3. Review Appendix C: Approval Drawings if the flowmeter is
located in a hazardous location.

4. Confirm the ProBar configuration.

5. Drill the correct size hole in the pipe.

• For ProBar models equipped with opposite-side support, drill a

second, identical hole 180 degrees from the first hole.

6. Weld the mounting, and clean the burrs and welds.

7. Measure the pipe’s internal diameter (ID), preferably at 1 x ID
from the hole (upstream or downstream).

NOTE

Providing the pipe internal diameter at the time of purchase is
necessary to maintain published flowmeter accuracy.

FIGURE 2-2.
Permissible Misalignment
for the ProBar.

The ProBar best produces accurate and repeatable flow measurement
under the following conditions:

• The maximum differential pressure, as printed on the tag
attached to the ProBar, is not exceeded.

• The ProBar is not used for two-phase flow or for steam service
below saturation temperature.

Install the ProBar in the correct location within the piping branch to
prevent measurement inaccuracies caused by flow disturbances.

ProBar installation allows for a maximum misalignment of 3 degrees,
as illustrated in Figure 2-2. Misalignment beyond 3 degrees will cause
errors in flow measurement.

3° max. 3° max.

Use Tabl e 2-1 to determine the proper ProBa r straight run requirements .

NOTES

For gas service, multiply values from Table 2-1 by 1.5.
If longer lengths of straight run are available, position the ProBar where

80% of the run is upstream of the ProBar and 20% is downstrea m.
Information contained in this manual applies to circular pipes only.

Consult the factory for instructions regarding ProBar use in square or
rectangular ducts.

Straightening vanes may be used to reduce the required straight run
length and will improve performance.

Row 6 in Table 2-1 applies to gate, globe, plug, and other throttling
valves that are partially opened. If a “through-type” valve will remain
open, use the values shown in Row 5. Refer to Row 6 for the straight
run requirements of a ProBar located downstream of the control valve.

Installation Location and Orientation

ENVIRONMENTAL
CONSIDERATIONS

ProBar Orientation

Horizontal Pipe:
Liquid or Steam Application

Location of the ProBar in pulsating flow will cause a noisy signal.
Vibration can also distort the output signal and compromise the
structural limits of the flowmeter. Mount the ProBar in a secure
run of pipe as far as possible from pulsation sources such as check
valves, reciprocating compressors or pumps, and control valves. Mount
the transmitter to minimize ambient temperature changes. Section 15:
Specifications and Reference Data lists the temperature operating
limits. Mount the transmitter to avoid vibration and mechanical shock;
mounting will also avoid external contact with corrosive materials. See
Section 8: ProBar Electronics Functions for environmental
considerations.

Proper venting or draining must be considered when selecting a
ProBar location.

For liquid service, mount the side drain/vent valve upward; this allows
gases to vent. For gas service, mount the drain/vent valve down to allow
any accumulated liquid to drain. In steam service, fill lines with water
to prevent contact of the li ve steam with the electronics; condensate
chambers are not needed because the volumetric displacement of the
electronics is negligible.

ProBar instrument head connections differ on horizontal and vertical
pipes. Refer to the specification head code number to confirm the
proper pipe orientation for your ProBar.

Due to the possibility of air getting trapped in the probe, the ProBar

should be located per the drawing below. The area between 0° and
50° (50° angle) should not be used unless full bleeding of air from the
probe is possible. Figure 2-3 illustrates the recommended location
of the flowmete r.

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

Process Connections
(Remote Mounted
ProBar only)

The ProBar process connections on the electronics flange are ¼–18 NPT .
Flange adapter unions with ½–14 NPT connections are supp lied as standard
with the remote mounted ProBar. The threads are Class 2; use your plant­approved lubricant or sealant when making the p rocess connections . The

1

process connections on the electronics flange are on 2

/8-inch (54 mm) centers
to allow direct mounting to a three-val ve or five-valve manif old. Rotate on e
or both of the flange adapters to at tain conne ction center s of 2 inches ( 51

1

mm), 2

/8 inc hes (54 mm) , or 2¼ inc hes (57 mm).

Install and tighten all four flange bolts before applying pressure, or
process leakage will result. When properly installed, the flange bolts
will protrude through the top of the module housing. Do not attempt to
loosen or remove the flange bolts while the ProBar is in service.

Perform the following procedure to install adapters to a
coplanar flange:

1. Remove the flange bolts.

2. Leaving the flange in place, move the adapters into
position with the o-ring installed.

3. Clamp the adapters and the coplanar flange to the
transmitter module using the larger of the bolts supplied.

4. Tighten the bolts. Refer to Mounting Bolts on page 2-8 for
torque specifications.

Failure to install proper flange adapter O-rings can cause process leaks, which can
result in death or serious injury.

The flange adapters require a unique O-ring, as shown below.

Flange Adapter

When compressed, Teflon

O-rings tend to cold flow, w hich aids in their
sealing capabilities. Whenever you remove flanges or adapters, visually
inspect the Teflon O-rings. Replace them if there are any signs of
damage, such as nicks or cuts. If they are undamaged, you may reuse
them. If the you replace the O-rings, retorque the flan ge bolts after
installation to compensate for cold flow. Refer to the process sensor body
reassembly procedure in Section 15: Troubleshooting.

Install the flowmeter within 40 degrees of the vertical axis to prevent
air from becoming entrapped within the sensor probe. Do not position

the ProBar within 50 degrees of the horizontal axis unless full bleeding
of air from the probe is possible. Figure 3-4 illustrates the recommended

location for the ProBar when used with steam service.

8900-8900_04A

All ProBar Regular models are shipped with the ProBar sensor
pre-assembled and the Pak-Lok nut, follower, and lock ring in place.
The factory-supplied weld fit ting with support ring is required to
install the ProBar. To prevent injury, remove pressure and drain
pipe before installing or removing the sensor.

STEP 2:
DRILL THE HOLE
IN THE PIPE

Drill a Hole for
Opposite-Side Support

Follow the steps below to drill the hole in the pipe.

1. Depressurize and drain the pipe.

2. Select the location for the hole you are about to drill.
Select a location anywhere around the circumference

of the pipe for vertical pipes.
For horizontal pipes, the hole location depends upon

the service for which t he ProBar is to be used:

• Liquid service: drill the hole along the bottom of the pipe

• Gas service: drill the hole along the top of the pipe

• Steam service: drill the hole along the bottom of the pipe

3. Determine the diameter of the hole to be drilled.
Use the chart in Figure 3-7.

4. After the hole is drilled, deburr the hole on the inside of the pipe.

A second hole must be drilled for the opposite-side support weld
coupling if opposite-side support is supplied. This hole must be the
same diameter as the first hole; place it directly opposite the
first hole so that the sensor can pass completely through the pipe.
Use the following steps to find t h e location for the second hole:

1. Wrap a piece of soft wire or string around the pipe to
measure the pipe’s circumference.

2. Remove the wire or string and measure half of the
circumference length.

3. Re-wrap the half-length around the pipe from the
center of the first hole.

4. Mark the center of what will become the second hole,
as shown in Figure 3-7.

Note: Drill the hole 180 degrees from the first hole
for opposite-side support models.

STEP 3:
TACK WELD THE
FITTINGS TO THE PIPE

FIGURE 3-8.
Tack Weld the Fittings to the Pipe.

Fol low these steps to tack weld the fittings to the pipe:

1. Insert the ProBar assembly into the factory-supplied weld fitting
(with integral support ring), then into the hole.

2. Align the head and electronics so they are parallel with the ground.

3. Tack weld the fitting(s) to the pipe and remove the ProBar. See
Figure 3-8 below.

The support ring shall be in-line or
parallel to plane of pipe as shown.

8900-8900V20A

NOTE

The larger radius in Figure 3-8 must be parallel to the centerline of
the pipe.

To protect the weld fitting threads from weld splatter, wrap the
factory-supplied heavy aluminum foil around the threads before
welding, or use a thread protector cap, as shown in Figure 3-9. Be sure
to allow the mounting to cool or serious burns may occur.

After the mounting hardware has cooled, install the adapter body and
support plug (for opposite-side support models), as shown in Figure
3-10. Use a sealant compound rated for use at the process temperature
on the threads.

NOTE

The adapter body must be threaded into the weld fitting before the
Pak-Lok nut is threaded onto the adapter body.

1. Mark the tip of the ProBar sensor with a marker.

2. Insert the flowmeter into the adapter body until the sensor tip
contacts the pipe wall (or support plug).

3. Remove the flowmeter.

4. Verify that the sensor tip touched the pipe wall. If the tip did not

touch the wall, adjust the adapter body until sensor tip touc hes the
wall, and re-install the ProBar.

5. Install the first packing ring on the ProBar between the lock
ring and the packing follower; take care not to damage the split
packing rings.

6. Push the pac kin g ri ng into the adapter body and agai n st the
weld-lock ring. Repeat this process for the two remaining rings,
alternating the location of the packing ring split by 180 degrees.

ProBar Flowmeter

NOTE

If the ProBar appears to be too long, go back to step 3. Verify
that the adapter body was installed into the weld fitting before the
ProBar was installed.

7. With the fl ow arrow on the ProBar head pointed in the direction
of the pipe flow, thread the Pak-Lok nut onto the adapter fitting
until it is hand tight only.

8. Use a wrench to tighten the Pak-Lok nut in ¼ turn increments

until it has been tightened one full turn. The Pak-Lok nut should
be tightened only enough to prevent leakage. Do not overtighten
the Pak-Lok nut; damage to the sensor will result.

NOTE

Use a maximum of 1¼ turns when installing the sensor. This is critical
when installing ProBar models with a sensor size of 15 or 16.
