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.

repeatable flow measurements. Refer to Table 2 for minimum pipe diameter
distances from upstream and downstream disturbances.

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 Ta b l e 2 applies to gate, globe, plug, and other throttling valves that

are partially opened, as well as control valves.

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.

Recommended

Zone

60°

60° 60°

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 Ta bl e 3).

Table 3. Sensor Size/Hole Diameter Chart

Quick Start Guide

Sensor

size

1 0.590-in. (14,99 mm)

Sensor width Hole diameter

/4-in. (19 mm) +1/32-in (0,8 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 3 . Drill the mounting hole into the pipe with a hole saw
or drill. DO NOT TORCH CUT THE HOLE.

Drill to Hole Size

P/N: 28-109001-922 Rev. AC

When drilling the mounting hole, Emerson™ Process Management recommends the use of a magnetic drill o r
pipe clamping fixture to safely drill the hole. Use appropriate personal protective equipment and procedures
when drilling and weldin g.

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.

Quick Start Guide

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.

B. Tack welds

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.

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.

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.
