 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 Ta bl e 1 applies to gate, globe, plug, and other throttling valves that

are partially opened, as well as control valves.

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).

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).

3 1.935-in. (49,15 mm) 21/2-in. (64 mm) +1/16-in. (1,6 mm) – 0.00

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 Ta bl e 2 . Drill the mounting hole into the pipe with a hole saw
or drill. DO NOT TORCH CUT THE HOLE.

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.

Drill the appropriate diameter hole
through the pipe wall.

Quick Start Guide

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

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.

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
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

1

tubing with

/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.
