2.3 Considerations
2.3.1 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.
The flowmeter can be installed with a maximum misalignment of 3 degrees (see Figure
2-1). Misalignment beyond 3 degrees will cause flow measurement errors.
Reference Manual
00809-0100-4809, Rev DA

3° max. 3° max.
2.3.2 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.
3° max.
Access requirements
Consider the need to access the flowmeter when choosing an installation location and
orientation.

Installation
Reference Manual
00809-0100-4809, Rev DA
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.
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 or 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.

2.5.4 Instrument manifolds
Figure 2-5 on page 10 identifies the valves on a 5-valve and a 3-valve manifold. Table 2-1 on
page 10 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 transmitter 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.

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.

2.5.6 Flowmeter orientation
Liquid
Due to the possibility of air getting trapped in the Annubar sensor, it should be located
according to Figure 2-7 for liquid applications. It should be mounted between 15° to 45° from
vertical down to ensure that air is vented from the Annubar sensor, and that sediment or solid
particles are not collected within the Annubar sensor.
For liquid applications, mount the side drain/vent valve upward to allow the gases to vent. In
vertical lines, the Annubar sensor 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.
For a remote mounted transmitter, mount the transmitter below the process piping, adjust 10°
to 15° above direct vertical down. Route the impulse piping down to the transmitter and fill the
system with cool water through the two cross fittings.

Gas
Figure 2-8 illustrates the recommended location of the flowmeter in gas applications. The
sensor should be located on the upper half of the pipe, at least 45° above the horizontal line.
For gas applications, mount the drain/vent valve downward to allow liquid to drain. In vertical
lines, the Annubar sensor 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.
For a remote mounted transmitter, secure the transmitter above the Annubar sensor to prevent
condensible liquids from collecting in the impulse piping and the DP cell.

Steam
In steam applications, fill the lines with water to prevent the steam from contacting the
transmitter. Condensate chambers are not required because the volumetric displacement of the
transmitter is negligible.
For a remote mounted transmitter, mount the transmitter below the process piping, adjust to
10° to 15° above direct vertical down. Route the impulse piping down to the transmitter and fill
the system with cool water through the two cross fittings.
Top mounting for steam applications is an appropriate mounting option in many cases. Consult
Rosemount Customer Central for instructions regarding steam on top mounting.

Note
For wet steam, do not mount the flowmeter at the direct vertical position. Mounting at an angle
will avoid measurement inaccuracy due to water running along the bottom of the pipe.
2.5.7 Remote mounted transmitter
Instrument head connections differ between horizontal and vertical pipes. For horizontal lines,
the instrument connections are parallel to the pipe and for vertical lines, the instrument
connection are perpendicular.
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 Annubar sensor is properly oriented for the intended type of service:
liquid, gas, or steam (see “Flowmeter orientation” on page 14).
Impulse piping
Impulse piping connects a remote mounted transmitter to the Annubar sensor. Temperatures in
excess of 250 °F (121 °C) at the transmitter will damage electronic components; impulse piping
allows service flow temperatures to decrease to a point where the transmitter is no longer
vulnerable.

and heat tracing to prevent freezing.
For installations where the transmitter is more than 6-ft. (1.8m) from the Annubar
sensor, 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
