NOTE
• Consult the factory for instructions regarding use in square or rectangular ducts.
• “In Plane A” means the sensor is in the same plane as the elbow. “Out of Plane A”
means the sensor 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.

Horizontal Orientation
For proper venting and draining, the sensor should be located in the upper half of the pipe
for air and gas applications. For liquid and steam applications, the sensor should be located
in the bottom half of the pipe. The maximum temperature for a direct mounted transmitter is
500 °F (260 °C).
NOTE:
For steam applications with DP readings between 0.75 and 2 inH2O in horizontal pipes, it is
recommended to install the primary element / flowmeter mounting above the pipe.

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. For steam applications, a 90° spacer will be added to provide
water legs to ensure the transmitter stays within temperature limits. The maximum
temperature for a direct mounted transmitter is 500 °F (260 °C).

STEP 2: DRILL HOLES 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: 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 485 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 4 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 4: WELD MOUNTING HARDWARE
1. Center the flanged assembly over the mounting hole, gap 1/16-in. (1,6 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 9). 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.
Figure 9. Alignment
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. (1,6 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
sensor is centered in the opposite side fitting and the plug will fit around 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.
4. To avoid serious burns, allow the mounting hardware to cool before continuing.

STEP 5: INSERT THE ANNUBAR
1. Align the flow arrow on the head with the direction of flow. Assemble 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. If opposite side support is threaded, apply an appropriate thread sealing compound to
the support plug threads and tighten until no leakage occurs.
4. If opposite side support is a socket weld fitting, insert the plug into the sockolet fitting
until the parts contact. Retract the plug 1/16-in. (1,6 mm) remove the Annubar sensor and
apply fillet weld per local codes.
STEP 6: 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 PTFE O-rings into grooves on the 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 400 in•lb (45 N•m).
Transmitter Mounting with Remote Mount Head
Temperatures in excess of 250 °F (121 °C) at the 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 1/2-in. (12 mm) outer diameter stainless steel tubing with a wall thickness of at least
0.035-in. (0,9 mm) is recommended including and under 600# ANSI (DN50 PN100). Above
600# ANSI (DN50 PN100), stainless steel tubing with 1/16-in. wall thickness.Threaded pipe
fittings are not recommended because they create voids where air can become entrapped
and create leakage points.

STEP 6 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 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 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
electronics.

Steam or Liquid Service (below 600 °F (315 °C))
Mount the transmitter below the process piping, adjust 10 to 15 degree above direct vertical
down. Route the impulse piping down to the transmitter and fill the system with water
through the two cross fittings.
NOTE
Ensure the drain legs are long enough to capture the dirt particles and sediment.
Top Mounting for Steam Service
(required for steam temperatures above 600 °F (315 °C))
This orientation can be used for steam at any temperature. However, it is required 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.
