Instrument ManifoldsFigure 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
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.
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.

Flowmeter OrientationLiquid
Due to the possibility of air getting trapped in the Annubar sensor , it should
be located according to Figure 2-5 for liquid applications. It should be
mounted between 15° to 45° from vertical down to ensure that air is vented
from the Annubar , and that sediment or solid particle s are not collect within
the Annubar.
For liquid applications, mou nt the side drain/vent valve up ward 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, depe nding 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 2-6 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, depe nding on the location.
For a remote mounted transmitter, secure the transmitter above the
Annubar sensor to prevent condensable liquids from collecting in the
impulse piping and the DP cell.

Top Mounting for Steam
This orientation can be used for any steam temperature. However, it is
recommended for installations above 600 °F (315 °C). For remote mount
installations, the impulse piping should slope up slightly from the instrument
connections on the Annubar to the cross fittings, allowing condensate to drain
back into the pipe. From the cross fittings, the impulse piping should be ro uted
downward to the transmitter and the drain legs. The transmitter should be
located below the instrument connections of the Annubar. Depending on the
environmental conditions, it may be necessary to insulate the mounting
hardware. The temperature limit for top mountin g a Dire ct Mou nt flowme ter is
400 °F (205 °C).

NOTE
For wet steam, do not mount the flowmeter at the

Instrument head connections differ between horizo nt al and vertical pipes. For
horizontal lines, the instrument connections are parallel to the pipe and for
vertical lines, the instrument connection ar e pe rp e ndi cu lar.
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 th e Annubar sensor is properly oriented for the intended type
of service: liquid, gas, or steam (see “Flowmeter Orientation” on
page 2-10).

Annubar Flowmeter Series
Impulse Piping
Impulse piping connects a remote mounted tra nsmitter to the Annubar se nsor .
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.
The following restrictions and recommendations apply to impulse piping
location.
•Piping used to connect the Annubar sensor and transmitter 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
(83 mm/m).
•With the Annubar mounted below the pipe, impulse piping must slope
downwards (toward the transmitter) for liquid and steam applications.
•With the Annubar mounted above the pipe, impulse piping must slope
up (toward from the transmitter) for gas and top mount steam
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.
•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 transmitter temperature. Impulse piping must be uninsulated
to reduce fluid temperature. All threaded connections should be
checked after the system comes up to temperature, beca u se
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 preven t fre e zing .
•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 recomme nded 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.
Note
For wet steam, do not mount the flowmeter at the
direct vertical position. Mounting at an angle will
avoid measurementinaccuracy due to water
running along the bottom of the pipe.
