NOTE
• For gas service, multiply values from Table 1 by 1.5.
• Consult the factory for instructions regarding use in square or
rectangular ducts.
• “In Plane A” means the bar is in the same plane as the elbow.
“Out of Plane A” means the bar is perpendicular to the plane of
the elbow.
• If proper lengths of straight run are not available, position the
mounting such that 80% of the run is upstream and 20% is
downstream.
• Use straightening vanes to reduce the required straight run
length.
• Row 6 in Table 1 applies to gate, globe, plug, and other
throttling valves that are partially opened, as well as control
valves.

Vertical Orientation
The sensor can be installed in any position around the circumference
of the pipe provided the vents are positioned properly for bleeding or
venting. Optimal results for liquid or steam are obtained when flow is
up. The preferred orientation for air or gas is flow down, but upwards
flow is acceptable. For steam applications, a 90° spacer will be added
to provide water legs to ensure the transmitter stays within
temperature limits.

STEP 2: DRILL HOLE INTO PIPE
1. Determine the sensor size based on the probe width (see Table 2).
2. Depressurize and drain the pipe.
3. Select the location to drill the hole.
4. Determine the diameter of the hole to be drilled according to the
specifications in Table 2. Drill the mounting hole into the pipe with a
hole saw or drill. DO NOT TORCH CUT THE HOLE.
Table 2. Sensor Size / Hole Diameter Chart
5. If 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 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.
6. Deburr the drilled holes on the inside of the pipe.

STEP 3: WELD MOUNTING HARDWARE
1. Center the flanged assembly over the mounting hole, gap 1/16 in.
(1.5 mm), and measure the distance from the outer diameter of the
pipe to the face of the flange. Compare this to Table 3 and adjust
the gap as necessary.
Table 3. Flange Sizes and ODF Per Sensor Size
2. Place four 1/4-in. (6-mm) tack welds at 90° increments. Check
alignment of the mounting both parallel and perpendicular to the
axis of flow (see Figure 7). If alignment of the mounting is within
tolerances, finish weld per local codes. If alignment is outside of
specified tolerance, make adjustments prior to making the finish
weld.

Insert the sensor into the mounting hardware. Verify that the tip of
the sensor is centered in the opposite side fitting and verify 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.

STEP 4: INSERT THE ANNUBAR
1. Align the flow arrow on the head with the direction of flow. Assembly
the bar to the mounting flange using a gasket, bolts, and nuts.
2. Tighten the nuts in a cross pattern to allow even compression of
the gasket.
3. Thread the studs into Flange-Lok body.
4. To ensure that the flowmeter contacts the opposite side wall, mark
the tip of the sensor with a marker. (Do not mark if ordered with
option code P2 or PA.)
5. Insert the flowmeter into the Flange-Lok body until the sensor tip
contacts the pipe wall (or support plug), rotating the flowmeter back
and forth.
6. Remove the flowmeter.
7. 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 outer diameter of the pipe and re-insert.
8. Re-insert the flow meter into the Flange-Lok body and install the
first packing ring on the sensor between the retaining ring and the
packing follower. Take care not to damage the split packing rings.
9. 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°.

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.

STEP 5: MOUNT THE TRANSMITTER
Transmitter Mounting, Direct Mount Head with Valves
It is not necessary to retract the Annubar when direct mounting a
transmitter with valves.
1. Place Teflon®(PTFE) O-rings into grooves on the face of 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 400 in•lb (45 N•m).
Transmitter Mounting, Direct Mount Head without Valves
1. Place Teflon (PTFE) O-rings into grooves on the face of head.
2. Orient the equalizer valve(s) so they are easily accessible. Install a
manifold with the smooth face mating to the face of the head.
Tighten in cross pattern to a torque of 400 in•lb (45 N•m).
3. Place Teflon (PTFE) O-rings into grooves on the face of the
manifold.
4. 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.
5. Tighten the nuts in a cross pattern to 400 in•lb (45 N•m).
Transmitter Mounting with Remote Mount Head
Temperatures in excess of 250 °F (121 °C)at the electronics will
damage the transmitter. Remote mounted electronics are connected to
the sensor by means of impulse piping, which allows service flow
temperatures to decrease to a point where the electronics are 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 1/2in. (12
mm) outer diameter stainless steel tubing with a wall thickness of at
least 0.035 in. (1 mm) is recommended. Threaded pipe fittings are not
recommended because they create voids where air can become
entrapped and create leakage points.

September 2003 Flange-Lok 485 Annubar
STEP 5 CONTINUED...
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 electronics) for liquid and steam
applications
• Slope upward (toward the electronics) for gas applications.
2. For applications with temperature below 250°F (121 °C), impulse
piping should be as short as possible to minimize temperature
changes. Insulation may be required.
3. For applications above 250 °F (121 °C), 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.
4. Outdoor installations for liquid, saturated gas, or steam may require
insulation and heat tracing to prevent freezing.
5. 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.
6. 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.
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 electronics.
