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 particles are not collect within
the Annubar.
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 2-6 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, depending 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.

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
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 routed
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 mounting a Direct Mount flowmeter is
400 °F (205 °C).

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

avoid measurement inaccuracy due to water
running along the bottom of the pipe.
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 2-10).

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.
The following restrictions and recommendations apply to impulse piping
location.
2-14
•
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, because
connections may be loosened by the expansion and contraction
caused by temperature changes.
•
A minimum of 1/2-in. (12mm) outer diameter (OD) stainless steel tubing
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 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® PST® Sealant is
recommended.

Drill the appropriate
diameter hole through
the pipe wall.
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 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.
6.
Deburr the drilled hole(s) on the inside of the pipe.

Step 3: Weld the Mounting Hardware
1.
Center the Pak-Lok body over the mounting hole, gap 1/16-in. (1.5 mm)
and place four 1/4-in. (6-mm) tack welds at 90° increments.
2.
Check alignment of the Pak-Lok body both parallel and perpendicular
to the axis of flow. If alignment of mounting is within tolerances (see
Figure 2-14), finish weld per local codes. If alignment is outside of
specified tolerance, make adjustments prior to finish weld.

Welds
3.
If opposite side support is being used, center the fitting for the
opposite side support over the opposite side hole, gap 1/16-in. (1.5
mm) and place four 1/4-in. (6 mm) tack welds at 90° increments. Insert
the sensor into the mounting hardware. Verify that the tip of the bar is
centered in the opposite side fitting and verify that the plug will fit
around bar. If the bar is centered in the fitting and plug fits around the
bar, finish weld 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.
4.
To avoid serious burns, allow the mounting hardware to cool before
continuing.
Step 4: Insert Annubar
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 or PA.)
3.

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 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 2-1, drill the hole into the
pipe with a hole saw or drill. Do not torch cut the hole.

Step 3: Assemble and check Fit-Up
For accurate measurement, use the following steps to ensure that Ports 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 1/16-in. (1.6 mm).
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.

mm) and place four 1/4-in. (6-mm) tack welds at 90° increments. Insert
the sensor into the mounting hardware. Verify that the tip of the bar is
centered in the opposite side fitting and that the plug will fit around the
bar. If the sensor is centered in the fitting and plug fits around the
sensor, finish weld per local codes. If alignment of the sensor does
not allow enough clearance to insert the opposite side plug, make the
necessary adjustments prior to making the finish weld. The Annubar
sensor must be removed before welding or installing the opposite
side support plug.
4.
To avoid serious burns, allow the mounting hardware to cool
before continuing.
Step 4: Insert into Pipe
2-32
1.
After the mounting hardware has cooled, use the following steps for
installation.
2.
Assemble the sensor flange to the mounting flange using gasket,
studs, and nuts.
3.
Tighten the nuts in a cross pattern to allow even compression of
the gasket.
4.
Thread studs into Flange-Lok body.
5.
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 or PA.)
6.
Insert the flowmeter into the Flange-lok body until the sensor tip
contacts the pipe wall (or support plug), rotating back and forth.
7.
Remove the flowmeter.

8.
Verify that the sensor tip made contact with the pipe wall by 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 the mounting body from the
OD of the pipe and re-insert.
9.
Re-insert the flowmeter into the Flange-Lok body and install the first
packing ring on the sensor between the lock ring and the packing
follower. Take care not to damage the split packing rings.
10. Push the packing ring into the Flange-Lok body and against the weld
retaining ring. Repeat this process for the two remaining rings,
alternating the location of the packing ring split by 180°.

11. Tighten the nuts onto the studs:
a. Place the included split-ring lock washer between each of the nuts
and the compression plate. Give each nut one half (1/2) turn in
succession until the split-ring lock washer is flat between the nut
and the compression plate. Torque is as follows:

b. Inspect the unit for leakage; if any exists, tighten the nuts in
one-quarter (1/4) turn increments until there is no leakage.
NOTE
On sensor size (1), failure to use the split-ring Lock washers, improper
washer orientation, or over-tightening the nuts may result in damage to the
flowmeter.

Step 2: Drill Mounting Hole into Pipe
1.
Depressurize and drain the pipe.
2.
At the predetermined position, drill the hole into the pipe wall 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 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. Re-wrap 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 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 ordered
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.

March 2012
Weld the weldolet and packing gland assembly to the pipe.
a. Place alignment bar back into the pipe, slide the weldolet and
packing gland assembly down the alignment bar, and let it rest on
the pipe.
b. Ensure the 11/8-in. (29 mm) holes in the support plate are
perpendicular to the pipe centerline within ± 3° for horizontal lines
and parallel to the pipe centerline within ± 3° for vertical lines. This
will ensure that the impact and static holes will be in line with the
flow stream. See Figure 2-3 on page 2-6.
c. Tack weld the weldolet to the pipe. Check alignment. Remove the
alignment bar and weld the first pass. Emerson Process
Management recommends using TIG welding for the first two
passes as a minimum. Experience has shown that welding about 1/2
to 2/3 of the weld using GTAW (TIG) and then using other weld
processes (GMAW, SMAW, FCAW) leads to lower chances of
movement of the weldment during welding.
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.
d. Check the alignment after the first pass. Remove the alignment bar
and weld the next pass. Recheck alignment.
e. Continue applying weld passes and rechecking alignment until
welding is complete. The fillet welds will be approximately 11/8-in.
(29 mm).
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.

5.
Perform required heat treatment.
6.
Reinstall 585 Main Steam Annubar after heat treating and ensure flow
arrow is pointing in the direction of flow.

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 page 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.
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 connections 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-designed 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 Protection Terminal Block. Consult
the factory for instructions.
