assist you with any needed information or materials.
The center will ask for the following information:
• Product model
• Serial numbers
• The last process material to which the product was exposed
The center will provide
• A Return Material Authorization (RMA) number
• Instructions and procedures that are necessary to return goods that
were exposed to hazardous substances
NOTE
If a hazardous substance is identified, a Material Safety Data Sheet (MSDS),
required by law to be available to people exposed to specific hazardous
substances, must be included with the returned materials.
CONSIDERATIONS Information in this manual applies to circular pipes only. Consult Rosemount

Limitations Structural
Structural limitations are printed on the sensor tag. Exceeding structural
limitations may cause sensor failure.
Functional
The most accurate and repeatable flow measurement occurs in the following
conditions:
• The structural limit differential pressure, as printed on the sensor tag, is
not exceeded.
• The instrument is not used for two-phase flow or for steam service
below saturation temperature.
Install the flowmeter in the correct location within the piping branch to prevent
measurement inaccuracies caused by flow disturbances.

Environmental Mount the flowmeter in a location with minimal ambient temperature changes.
Appendix A: Specifications and Reference Data lists the temperature
operating limits. Mount to avoid vibration, mechanical shock, and external
contact with corrosive materials.
Access Requirements
Consider the need to access the flowmeter when choosing an installation
location and orientation.
Process Flange Orientation
Orient the process flanges on a remote mounted flowmeter so that process
connections can be made. For safety reasons, orient the drain/vent valves so
that process fluid is directed away from technicians when the valves are used.
In addition, consider the possible need for a testing or calibration input.
Housing Rotation
The electronics housing may be rotated up to 180 degrees (left or right) to
improve field access to the two compartments or to better view the optional
LCD meter. To rotate the housing, release the housing rotation set screw and
turn the housing up to 180 degrees.
1-3
Annubar Flowmeter Series
NOTE
Rotating the housing more than 180 degrees will damage the sensor module
and void the warranty.
Electronics Housing
Terminal Side
The circuit compartment should not routinely need to be opened when the
unit is in service. Wiring connections are made through the conduit
openings on the top side of the housing. The field terminal side is marked
on the electronics housing. Mount the flowmeter so that the terminal side
is accessible. A 0.75-in. (19 mm) clearance is required for cover removal.
Use a conduit plug on the unused side of the conduit opening. A 3-in. (76
mm) clearance is required for cover removal if a meter is installed.
Exterior
The integral span and zero push-buttons are located under the
certifications plate on the top of the ProBar. The plate will be blank if no
certifications are ordered.

Failure to install proper flange adapter O-rings can cause process leaks,
which can result in death or serious injury. There are two styles of Rosemount
flange adapters, each requiring a unique O-ring, as shown below. Each flange
adapter is distinguished by its unique groove.

their sealing capabilities. Whenever flanges or adapters are removed, visually
inspect the Teflon (PTFE) O-rings. Replace them if there are any signs of
damage. If the O-rings are replaced, the flange bolts may need to be
retorqued after installation to compensate for cold flow.
(PTFE) O-rings tend to cold flow when compressed, which aids in
Electrical The signal terminals are located in a compartment of the electronics housing.
Connections for the Model 275 HART Communicator are located below the
signal terminals. The Model 272 Field Calibrator can be connected at the
signal terminals to provide temporary power to the electronics for calibration
or diagnostic purposes. Otherwise, the calibrator may be attached to the test
connections on the terminal block of the electronics for indication purposes.
Power Supply
The dc power supply should provide power with less than 2% ripple. The total
resistance load is the sum of the resistance of the signal leads and the load
resistance of the controller, indicator, and related pieces. Note that the
resistance of intrinsic safety barriers, if used, must be included.
NOTE
A loop resistance between 250-1100 ohms is required to communicate with a
personal computer. With 250 ohms of loop resistance, a power supply voltage
of at least 16.5 V dc is required.
If a single power supply is used to power more than one Model 3095MFA
Mass ProBar, the power supply used, and circuitry common to the Mass
ProBars, should not have more than 20 ohms of impedance at 1200 Hz.

(1) Quick troubleshooting check: There must be at least 11.0 V DC across the Model 3095MFA
Mass ProBar electronics terminals.

Instrument Manifolds Figure 2-3 on page 2-6 identifies the valves on a 5-valve and a 3-valve
manifold. Table 2-1 on page 2-6 explains the purpose of these valves.
An instrument manifold is recommended for all installations. A manifold allows
an operator to equalize the pressures prior to the zero calibration of the
electronics as well as to isolate the electronics from the rest of the system
without disconnecting the impulse piping. Although a 3-valve manifold can be
used, a 5-valve manifold is recommended.
5-valve manifolds provide a positive method of indicating a partially closed or
faulty equalizer valve. A closed faulty equalizer valve will block the DP signal
and create errors that may not be detectable otherwise. The labels for each
valve will be used to identify the proper valve in the procedures to follow.
NOTE
Some recently-designed instrument manifolds have a single valve actuator,
but cannot perform all of the functions available on standard 5-valve units.
Check with the manufacturer to verify the functions that a particular manifold
can perform. In place of a manifold, individual valves may be arranged to
provide the necessary isolation and equalization functions.

Use the following to aid in determining the straight run requirements
NOTE
• For gas service, multiply values from Table 2-2 on page 2-7 by 1.5.
• If longer lengths of straight run are available, position the mounting
such that 80% of the run is upstream and 20% is downstream.
• The information contained in this manual is applicable to circular pipes
only. Consult the factory for instructions regarding use in square or
rectangular ducts.
• Straightening vanes may be used to reduce the required straight
run length.
• Row 5 in Table 2-2 is to be used if a “through type” valve will remain
open. Row 6 in Table 2-2 applies to gate, globe, plug, and other
throttling valves that are partially opened, as well as control valves.

Integral (Direct) Mount
NOTE
The integral mount flowmeter is usually shipped with the electronics bolted
directly to the sensor. If this is not so, contact Rosemount Customer Central
for more information.
Horizontal Pipes
Liquid or Steam Applications
Due to the possibility of air getting trapped in the probe, the sensor should
be located according to Figure 2-5 for liquid or steam applications. The
area between 0° and 30° angle should not be used unless full bleeding of
air from the probe is possible.
For liquid applications, mount the side drain/vent valve upward to allow the
gases to vent.
In steam applications, fill the lines with water to prevent the steam from
contacting the electronics. Condensate chambers are not required
because the volumetric displacement of the electronics is negligible.

Figure 2-5. Horizontal Pipe
Applications
Air and Gas Applications
Figure 2-5 illustrates the recommended location of the flowmeter in air or
gas applications. The sensor should be located on the upper half of the
pipe, at least 30° above the horizontal line.
For air and gas applications, mount the drain/vent valve downward to allow
liquid to drain.

Remote Mount Instrument head connections differ between horizontal and vertical pipes.
Consult your specification head code number to confirm the proper pipe
orientation.
Valves and Fittings
Throughout the remote mounting process:
• Use only valves, fittings, and pipe thread sealant compounds that are
rated for the service pipeline design pressure and temperature as
specified in Appendix A: Specifications and Reference Data.
• Verify that all connections are tight and that all instrument valves are
fully closed.
• Verify that the sensor probe is properly oriented for the intended type of
service: liquid, gas or steam (see Figures “Integral (Direct) Mount” on
page 2-8 and “Remote Mount” on page 2-9).
Impulse Piping
Impulse piping connects remote mounted electronics to the sensor.
Temperatures in excess of 250 °F (121 °C) at the electronics will damage
electronics components; impulse piping allows service flow temperatures to
decrease to a point where the electronics is no longer vulnerable.
The following restrictions and recommendations apply to impulse piping
location.
• Piping used to connect the sensor probe and electronics must be rated
for continuous operation at the pipeline-designed pressure and
temperature
• Impulse piping that runs horizontally must slope at least 1–in. per foot
(83mm/m).
• It must slope downwards (toward the electronics) for liquid and steam
applications.
• It must slope up (away from the electronics) for gas applications.
• For applications where the pipeline temperature is below 250 °F
(121 °C), the impulse piping should be as short as possible to minimize
flow temperature changes. Insulation may be required.
2-9
Annubar Flowmeter Series
• For applications where pipeline temperature is above 250 °F (121 °C),
the impulse piping should have a minimum length of 1-ft. (0.30 m) for
every 100 °F (38 °C) over 250 °F (121 °C), which is the maximum
operating electronics temperature. Impulse piping must be uninsulated
to reduce fluid temperature. All threaded connections should be
checked after the system comes up to temperature, because
connections may be loosened by the expansion and contraction
caused by temperature changes.
• A minimum of
with a wall thickness of at least 0.035-in. is recommended.
• Outdoor installations for liquid, saturated gas, or steam service may
require insulation and heat tracing to prevent freezing.
• For installations where the electronics are more than 6-ft. (1.8m) from
the sensor probe, the high and low impulse piping must be run together
to maintain equal temperature. They must be supported to prevent
sagging and vibration.
• Threaded pipe fittings are not recommended because they create voids
where air can become entrapped and have more possibilities for
leakage.
• Run impulse piping in protected areas or against walls or ceilings. If the
impulse piping is run across the floor, ensure that it is protected with
coverings or kick plates. Do not locate the impulse piping near high
temperature piping or equipment.
• Use an appropriate pipe sealing compound rated for the service
temperature on all threaded connections. When making threaded
connections between stainless steel fittings, Loctite
recommended.

4. If opposite-side support coupling is supplied, a second identically
sized hole must be drilled opposite the first hole so that the sensor
can pass completely through the pipe. (To determine a opposite-side
support model, measure the distance from the tip of the first slot or
hole. If the distance is greater than 1-in. (25.4 mm), it is the
opposite-side model.) To drill the second hole, follow these steps:
a. Measure the pipe circumference with a pipe tape, soft wire, or string
(for the most accurate measurement the pipe tape needs to be
perpendicular to the axis of flow).
b. Divide the measured circumference by two to determine the location
of the second hole.
c. Rewrap the pipe tape, soft wire, or string from the center of the first
hole. Then, using the number calculated in the preceding step, mark
the center of what will become the second hole.
d. Using the diameter determined from Table 2-3, drill the hole into the
pipe with a hole saw or drill. Do not torch cut the hole.
5. Deburr the drilled hole(s) on the inside of the pipe.

per local codes. If the alignment of the bar does not allow enough
clearance to insert the opposite side plug, make the necessary
adjustments prior to making the finish weld.
NOTE
To avoid serious burns, allow the mounting hardware to cool
before continuing.
Step 5: Insert into the Pipe
28-490000_906A04A
After the mounting hardware has cooled, use the following steps for
installation.
1. Thread studs into the Pak-Lok body.
2. To ensure that the flowmeter contacts the opposite side wall, mark
the
tip of the sensor with a marker. (Do not mark if the sensor was
ordered with special-cleaned option code P2.)
3. Rotating the flowmeter back and forth, insert the flowmeter into the
Pak-Lok body until the sensor tip contacts the pipe wall (or support
plug).
4. Remove the flowmeter.
5. Verify that the sensor tip made contact with the pipe wall by removing
the pipe and ensuring that some of the marker has been rubbed off.
For special-cleaned bars, look for wear marks on the tip. If the tip did
not touch the wall, verify pipe dimensions and the height of mounting
body from the OD of the pipe and re-insert.
6. Re-insert the flowmeter into the Pak-Lok body and install the first
packing ring on the sensor between the lock ring and the packing
follower. Do not damage the split packing rings.
7. Push the packing ring into the Pak-Lok body and against the weld
lock ring. Repeat this process for the two remaining rings, alternating
the location of the packing ring split by 180°.
