1.2 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).
Figure 3. Horizontal Orientation
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.

1.3 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).

2.0 Drill sensor holes
1. Determine the sensor size based on the probe width (see Table 2).
Table 2. Sensor Size/Hole Diameter Chart
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.
Sensor size Sensor width Hole diameter
10.590-in. (14,99 mm) 3/4-in. (19 mm) +1/32-in (0,8 mm) – 0.00
21.060-in. (26,92 mm) 15/16-in. (34 mm) +1/16-in. (1,6 mm) – 0.00
31.935-in. (49,15 mm) 21/2-in. (64 mm) +1/16-in. (1,6 mm) – 0.00
When drilling the mounting hole(s), Emerson™Process Management 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.

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.
6. Deburr the drilled holes on the inside of the pipe.
3.0 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 Rosemount 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 butt weld branch connection
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 3to the
last sensing hole, port A.
5. Compare the numbers obtained in steps 3and 4.
Small discrepancies can be compensated for with the fit-up of the mounting
hardware. Large discrepancies may cause installation problems or error.
Drill the appropriate diameter hole
through the pipe wall.

4.0 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 6). 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.

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.
5.0 Insert the Rosemount Annubar Sensor
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
socket-weld outlet fitting until the parts contact. Retract the plug 1/16-in.
(1,6 mm) remove the Rosemount Annubar Sensor and apply fillet weld per
local codes.
6.0 Mount the transmitter
6.1 Transmitter mounting, direct mount head with 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).

6.2 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.
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.

Top mounting for steam service
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
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.
