NOTICE
This guide provides basic guidelines for Rosemount 485. It does not provide instructions for configuration,
diagnostics, maintenance, service, troubleshooting, Explosion-proof, Flameproof, or Intrinsically Safe (I.S.)
installations. Refer to Rosemount 485 Annubar Reference Manual for more instruction. This manual is also
available electronically on EmersonProcess.com/Rosemount.
If the Rosemount 485 was ordered assembled to a Rosemount Pressure Transmitter, see the following Quick
Start Guides for information on configuration and hazardous locations certifications:

Process leaks may cause harm or result in death. To avoid process leaks, only use packings designed to seal
with the recommended torque value to seal process connections. Flowing medium may cause the
Rosemount 485 Annubar Assembly to become hot and could result in burns.

Quick Start Guide
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 Table 2 applies to gate, globe, plug, and other throttling valves that
are partially opened, as well as control valves.
1.1 Misalignment
Rosemount 485 installation allows for a maximum misalignment of 3°.

Quick Start Guide
1.3 Top mounting the flowmeter for steam
Top mounting for steam applications is an alternate mounting option in some
cases. Consult Rosemount Customer Central for instructions regarding steam on
top mounting. 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, top mounting can reduce or eliminate
the need for heat tracing in outdoor applications that do not experience
shutdowns during cold weather.
Figure 7. Remote Mount; Horizontal Top Mounting for Steam
This orientation can be used for any steam temperature. 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 primary element. Depending
on the environmental conditions, it may be necessary to insulate the mounting
hardware.

2.0 Drill sensor holes
1. Determine the sensor size based on the probe width (see Table 3).
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 3. Drill the mounting hole into the pipe with a hole saw
or drill. DO NOT TORCH CUT THE HOLE.
3.0 Prepare for welding
1. Clean off the coating on the bottom of the weld coupling to get the best weld
penetration effect.
2. For specific process fluid, the anti-rust oil inside the weld coupling may need to
be rinsed thoroughly before welding. If you are not sure about your process
fluid, contact an Emerson Process Management representative.
Table 3. Sensor Size/Hole Diameter Chart
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
When drilling the mounting hole, 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.

4.0 Weld the mounting hardware
1. Center the threaded body over the mounting hole, gap 1/16-in. (1,6 mm), and
place four 1/4-in. (6 mm) tack welds at 90° increments.
2. Check alignment of the threaded body both parallel and perpendicular to the
axis of flow (see Figure 8). If alignment of mounting is within tolerances
defined in Figure 3, finish weld per local codes. If alignment is outside of
specified tolerance, make adjustments prior to finish weld.
Figure 8. Alignment
3. To avoid serious burns, allow the mounting hardware to cool before
continuing.
4. For flat duct surfaces, the bottom of the weld coupling needs to be ground for
mounting. The welding height remains the same as LMH value for respective
sensor size.
5.0 Insert the Rosemount Annubar Sensor
Note
Refer to “Rosemount 485 Annubar Threaded Assembly Exploded View” on page 3 for
component descriptions.
1. To ensure the primary element contacts the opposite side pipe wall, mark the
tip of the sensor with a marker.
2. Insert the flowmeter into the threaded body until the sensor tip contacts the
pipe wall, twisting the primary element back and forth.
A. Lower Mounting Height LMH(1)
1. LMH values are as follows:
Sensor size 1 — 2.89-in.(73 mm)
Sensor size 2 — 3.92-in.(100 mm)
B. Tack welds

3. Verify the sensor tip made contact with the opposite side pipe wall by
removing the primary element and ensuring that some of the marker has been
rubbed off. If the tip did not touch the wall, verify the measured pipe ID and
wall match the tagging information and re-insert.
4. Align the flow arrow on the head with the direction of flow. Re-insert the
primary element into the threaded weld coupling and install the first packing
ring on the sensor between the retaining ring and the follower. Take care not
to damage the split packing rings.
5. Install packing rings.
a. Install the first packing ring underneath the follower.
b. Use the follower 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° to each other.
d. Use the follower to compress the second packing ring against the first
packing ring.

e. Install the third packing ring underneath the follower.
f. Use the follower to compress the third packing ring.
6. Tighten the nut to the specified torque.
Table 4. Torque Requirements
a. Inspect the unit for leakage.
b. If any leaks exist, tighten the nut in 1/4turn increments until there is no
leakage.
Note
Do not exceed the maximum torque listed in Table 4.
Note
The threaded sealing mechanism will 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.
