SAFETY MESSAGES Instructions and procedures in this section may require special precautions to

ensure the safety of the personnel performing the op erations. Please refer to
the following safety messages before performin g any op eration in thi s section.

If pipe/duct wall is less than .125” (3.2mm) use extreme caution when installing sensor. Thin
walls can deform during welding, installation, or from the weight of a cantilevered flowmeter.
These installations may require a fabricated outlet, saddle, or external flowmeter support.
Please consult factory for assistance.

Explosions could result in death or serious injury:

• Do not remove the transmitter cover in explosive atmospheres when the circuit is
live.

• Before connecting a Field Communicator in an explosive atmosphere, make sure
the instruments in the loop are installed in accordance with intrinsically safe or
non-incendive field wiring practices.

• Verify that the operating atmosphere of the transmitter is consistent with the
appropriate hazardous locations certifications.

• Both transmitter covers must be fully engaged to meet explosion-proof
requirements.

Failure to follow these installation guidelines could result in death or serious injury:

• Make sure only qualified personnel perform the installation.

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
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 Orientation Liquid

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).

Transmitter

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.

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).

2-13

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.

5. 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 an 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 tap e, sof t 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 determin e 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.

6. Deburr the drilled hole(s) on the inside of the pipe.

5. 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 drill the second hole, follow
these steps:

a. Measure the pipe circumference with a pipe tap e, sof t 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 determin e 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 2-1, drill the hole into the

pipe with a hole saw or drill. Do not torch cut the hole.

6. Deburr the drilled holes on the inside of the pipe.

Step 3: Assemble and check Fit-Up

For accurate measurement, use the following step s to ensure that Port s A and
B are equal distances from the inside walls of the pipe.

1. Assemble the Annubar sensor to the mounting hardware with the
gaskets and bolts.

2. Hand tighten the bolts just enough to hold the position of the sensor
centered in the mounting hardware.

3. Measure the distance from the high point of the weldolet to the first
sensing hole, port B, then subtract

4. Measure the distance from the end of the transferred length in step 3
to the last sensing hole, port A.

5. Compare the numbers obtained in steps 3 and 4.

Small discrepancies can be compensated for with the fit-up of the mounting
hardware. Large discrepancies may cause installation problems or error.

Step 2: Drill Mounting Hole into Pipe

1. Depressurize and drain the pipe.

2. At the predetermined position, dr ill th e ho le int o th e pip e wa ll in
accordance with the instructions provided by the drilling machine
manufacturer. Drill 2.5 in. (64 mm) hole. Drill hole has a tolerance of
+1/16 in./ -0 in. (1,6 mm/ -0 mm).

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

4. A second identically sized hole must be drilled opposite the first hole
so that the sensor can pass completely through the pipe. 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 need s to
be perpendicular to the axis of flow.)

b. Divide the measured circumference by two to de te rm in e th e

location of the second hole.

c. Re-wrap the pipe tape, soft wire, or string from the center of the

first hole. Then, using the number calculated in the pr eceding step,
mark the center of what will become the second hole.

d. Using the diameter determined in step 3, drill the hole into the pipe

with a hole saw or drill. Do not torch cut the hole.

5. Deburr the drilled holes on the inside of the pipe.

Step 3: Weld the Mounting Hardware

1. An alignment bar is needed during the welding of the heavy wall
weldolets to the steam pipeline. The alignment bar can be orde red
from Emerson Process Management.

2. Weld the heavy wall weldolet to the packing gland assembly with a
full penetration-groove weld.

a. Place the alignment bar through the packing gland and the

weldolet. The weldolet will also have a bearing sleeve in it and it
should be near the radius end of the weldolet which will be the end
welded to the pipe. Ensure the support plate is attached to the
packing gland before making the weld.

b. Tack weld the weldolet to the packing gland. Remove the alignment

bar.

c. Weld the first pass. Recheck alignment with the alignment bar.

Adjust alignment as necessary. Do not allow the alignment bar to
get too hot, as it will be difficult to remove. Use it only briefly to
check alignment between weld passes.

d. Complete remaining weld passes, using alignment bar to verify

alignment several times during the process. Emerson Process
Management recommends that the weld thickness is equal to the
base metal thickness.

NOTE:

It is very helpful to have two welders welding the assemblies to pipe, with one
welder starting 180° from the other. This helps prevent movement of the
fittings during the temperature changes associated with welding.

4. Weld the opposite side weldolet to the pipe.
a. Slide the alignment bar through mounting and hole in top side of

pipe and place the opposite-side support weldolet over the end of
the alignment bar.

b. Visually center the opposite-side weldolet over the hole. Tack weld

the weldolet, using tack bars or an equivalent method.

c. Weld the first pass and check alignment using the alignment bar

and continue welding. Check alignment frequently during welding.
Adjust weldolet as you are making tacks to keep aligned. Do not
leave alignment bar in too long as it will heat up and make it very
difficult to remove.

d. When welding is complete, the alignment bar should slide freely

through the packing into the opposite-side weldolet.

e. Weld opposite end cap to weldolet using a full penetration groove

weld.

Step 4: Insert the Annubar

1. Place the packing into the packing gland with the two split rings
(Garlock style 1303FEP) on the outside and the three Garlock
Carbon/Graphite solid die-formed rings on the inside. Make sure the
splits in the outer packing are 180° apart.

NOTE:

The packing gland and support plate will be shipped fully assembled.

2. Slide the 585 Annubar through the packing and install the locking
rods, nuts, and lock washers. The dimension between the plates
should be 11.0 in (279 mm). See Figure 2-37 on p age 2-51. If there is
visual access to the inside of the pipe, ensure that the sensing holes
are equally spaced from the inner diameter of the pipe.

3. Make the small adjustment (if necessary), then lock the 585 in place
with the locking rods, nuts, and lock washers. When installed, the 585
will have a dimension of 29.6 in (752 mm) from pipe OD to top of
head.

4. The last thing to be done is to tighten the packing gland nuts to 25 to
30 ft.-lbs. (34 to 41 Nm). See Figure 2-35.

Step 5: Mount the Transmitter

1. Impulse piping that runs horizontally must slope downward at least
one inch per foot (83 mm/m).

2. Impulse piping should have a minimum length of one foot (0.3048 m)
for every 100 °F (38 °C) temperature increase over 250 °F (121 °C).
Impulse piping must be non-insulated to reduce fluid temperature.
Any threaded connections should be checked after the system
reaches the intended temperature because connections may come
loose with contraction and expansion caused by temperature change.

3. Outdoor installations may require insulation and heat tracing to
prevent freezing.

4. When impulse piping is longer than six feet (1.8 m) the high and low
impulse lines must be positioned together to maintain equal
temperature. They must be supported to prevent sagging and
vibration.

5. Impulse lines should be positioned in protected areas or against walls
or ceilings. Use appropriate pipe sealing compound rated for the
service temperature on all threaded connections. Do not place the
impulse piping near high temperature piping or equipment.

a. An instrument manifold is recommended for all installations.

Reference Manual

Manifolds allow an operator to equalize the pressures prior to
zeroing and isolates the process fluid from the transmitter.

b. Use only valves and fittings rated for the design pressure and

temperature (in some cases the primary instrument valve may be
supplied by Emerson Process Management with the Annubar).

c. Use a pipe thread sealant compound that is rated for use at the

service temperature and pressure for all valves and fittings.

d. Verify that all connectio ns are tight and that all instrument valves

are fully closed.

e. Verify that the sensor probe is properly oriented as per the

submitted outline drawings.

f. The piping used to connect the sensor probe and transmitter must

be rated for continuous operation at the pipeline-d esigned pressure
and temperature. A minimum of one-half inch (1/2-in., 12 mm) O.D.
stainless steel tubing with a wall thickness of at least 1/16-in. (1,6
mm) is recommended.

Do not connect the powered signal wiring to the test terminals. Power may
damage the test diode in the test connection.

Plug and seal unused conduit connections on the electronics housing to avoid
moisture accumulation in the terminal side of the housing. Excess moisture
accumulation may damage the electronics. If the connections are not sealed,
the electronics should be remote mounted with the electrical housing
positioned downward for drainage. Wiring should be installed with a drip loop
and the bottom of the drip loop should be lower then the conduit connections
and the housing.

Inductive-based transient protectors, including the Rosemount 470 transient
protector, can adversely affect the output of the Annubar. If transient
protection is desired, install the Transient Pro te ction Terminal Block. Consult
the factory for instructions.

Wiring Diagrams 1. Remove the housing cover on the side marked FIELD TERMINALS.

Do not remove the instrument covers in explosive atmosp heres when
the circuit is live.

2. Connect the lead that originates at the positive side of the power
supply to the terminal marked “+” and the lead that originates at the
negative side of the power supply to the terminal marked “–.” Avoid
contact with the leads and terminals.
