Note

 Consult the factory for instructions regarding use in square or rectangular

ducts.

 If proper lengths of straight run are not available, position the mounting such

that 80% of the run is upstream and 20% is downstream. This will result in
degraded accuracy.

 Use straightening vanes to reduce the required straight run length.
 Row 6 in Ta b l e 1 applies to gate, globe, plug, and other throttling valves that

are partially opened, as well as control valves.

Quick Start Guide

1.3 Top mounting the flowmeter for steam

Top mounting in steam is an alternative mounting method for steam installations
that can be used if there are space restrictions or other concerns. This installation
method is intended for applications that run with limited interruptions or
shutdowns. Also, for outdoor applications, top mounting can eliminate the need
for heat tracing, if steam is flowing.

1. For wet steam, do not mount the flowmeter at the direct vertical position. Mou nting at an angle will avoid
measurement inaccuracy due to water running along the bottom of the pipe.

This orientation can be used for any steam temperature. For remote mount
installations, the impulse piping should slope up slightly from the instrument
connections on the Rosemount 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
Rosemount Annubar. Depending on the environmental conditions, it may be
necessary to insulate the mounting hardware.

Quick Start Guide

P/N: 28-109001-922 Rev. AC

When drilling the mounting hole(s), Emerson™ Process Manag ement recommends the use of a magnetic drill
or pipe clamping fixture to safely drill the hole. Use appropriate personal protective equipment and
procedures when drilling and welding.

11

Quick Start Guide

Drill the appropriate diameter hole
through the pipe wall.

5. Although it is not commonly selected, if an opposite-side support model 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 if you
have an opposite-side support model, measure the distance from the tip to
the first slot or hole. If the distance is greater than 1-in. (25,4 mm), it is the
opposite-side support 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. Re-wrap the pipe tape, soft wire, or string from the center of the first hole.

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

d. Using the diameter determined in step 4, drill the hole into the pipe with a

hole saw or drill. DO NOT TORCH CUT THE HOLE.

Note

Drill the hole 180° from the first hole for opposite- side support models.

3.0 Weld mounting hardware

1. Center the Pak-Lok body over the mounting hole, gap 1/16-in. (1,6 mm), and
place four

2. Check alignment of the Pak-Lok body both parallel and perpendicular to the
axis of flow (see Figure 8). If alignment of mounting is within tolerances, finish
weld per local codes. If alignment is outside of specified tolerance, make
adjustments prior to finish weld.

/4-in. (6 mm) tack welds at 90° increments. Insert the sensor into the
mounting hardware. Verify that the tip of the sensor is centered in the
opposite side fitting and that the plug will fit around sensor. Finish weld per
local codes. If the 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.

4. To avoid serious burns, allow the mounting hardware to cool before
continuing.

4.0 Insert the Rosemount Annubar Sensor

Note

Refer to “Rosemount 485 Annubar Pak-Lok Assembly Exploded View” on page 3 for
component descriptions.

1. Thread studs into the Pak-Lok body.

2. To ensure that the flowmeter contacts the opposite side pipe wall, mark the
tip of the sensor with a marker. (Do not mark if ordered with option code P2 or
PA. )

3. Insert the flowmeter into the Pak-Lok body until the sensor tip contacts the
pipe wall (or support plug), twisting the flowmeter back and forth.

4. Verify that the sensor tip made contact with the opposite side pipe wall by
removing the flowmeter and ensuring that some of the marker has been
rubbed off. For special-cleaned sensors, look for wear marks on the tip. If the
tip did not touch the wall, verify the measured pipe ID and wall match the
tagging information and re-insert.

6. Push the packing ring into the Pak-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 120°.
a. Install the first packing ring underneath the follower.

b. Use the follower and the compression plate to compress the first packing

ring against the retaining ring.

c. Install the second packing ring underneath the follower. Alternate packing

ring splits by 120 degrees to each other.

d. Use the follower and the compression plate to compress the second

packing ring against the first packing ring.

e. Install the third packing ring underneath the follower.
f. Use the follower and the compression plate to compress the third packing

ring against the second packing ring.

7. 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 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

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 flowmeter damage.

Note

Pak-Lok sealing mechanisms generate significant force at the point where the sensor
contacts the opposite pipe wall. Caution needs to be exercised on thin-walled piping (ANSI
Sch 10 and lower) to avoid damage to the pipe.

8. Verify that a gap exists between the compression plate and the Pak-Lok body.
If the gap is not within the tolerances shown in Ta bl e 4 , repeat steps 6 and 7 to
ensure the packing was installed correctly. If the gap is still not within
tolerances, contact your Emerson Process Management representative for
technical support.

5.0 Mount the transmitter

5.1 Mounting a transmitter with a direct mount head and valves

It is not necessary to retract the Rosemount Annubar when direct mounting a
transmitter with valves.

1. Place PTFE O-rings into grooves on the Rosemount Annubar Head.

2. Align the high side of the transmitter to the high side of the sensor (“Hi” is
stamped on the side of the head) and install.

3. Tighten the nuts in a cross pattern to 384 in-lb (43 N-m).

5.2 Mounting a transmitter with a remote mount head

Temperatures in excess of 250 °F (121 °C) at the transmitter sensor module
diaphragms will damage the transmitter. Remote mounted transmitters are
connected to the sensor by means of impulse piping, which allows process
temperatures to decrease to a point where the transmitter is no longer
vulnerable.

Different impulse piping arrangements are used depending on the process fluid
and must be rated for continuous operation at the pipeline design pressure and
temperature. A minimum of
with a wall thickness of at least 0.035-in. (0,9 mm) is recommended for 600#
ANSI (DN50 PN100) and below. Above 600# ANSI (DN50 PN100), stainless steel
tubing with a minimum wall thickness of
are not recommended because they add potential leak points.
The following restrictions and recommendations apply to impulse piping
location:

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

- Slope downward (toward the transmitter) for liquid and steam applications.

- Slope upward (toward the transmitter) for gas applications.

2. Outdoor installations for liquid, saturated gas, or steam may require insulation
and/or heat tracing to prevent freezing.

3. 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.
