NOTICE
This guide provides basic guidelines for Rosemount 485 Annubar. 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
instruction. This manual is also available electronically on Emerso nProcess.com/Rosemount
If the Rosemount Annubar was ordered assembled to a Rosemount Pressure Transmitter, see the following

Process leaks may cause harm or result in death. To avoid process leaks, only use gaskets designed to seal with
the corresponding flange and o-rings to seal process connections. Flowing medium may cause the
Rosemount 485 Annubar Assembly to become hot and could result in burns.

1.0 Location and orientation
Correct orientation and straight run requirements must be met for accurate and
repeatable flow measurements. Refer to Table 1 for minimum pipe diameter
distances from upstream disturbances.

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 Ta bl e 1 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°.

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).

Top mounting for steam applications is an appropriate mounting option in many cases.

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 Weld mounting hardware
Note
Rosemount-supplied mounting has an integral alignment built into the mounting hardware
that assists in the correct drilling of the mounting hole. It also assists in the alignment of the
sensor to the mounting hole for insertion.

1. At the pre-determined position, place the threaded weld coupling on the pipe,
1
/16-in. (1,6 mm), and place four 1/4-in. (6 mm) tack welds at 90°
gap
increments.
2. Check alignment of the mounting both parallel and perpendicular to the axis
of flow (see Figure8). If alignment of the mounting is within tolerances, finish
weld per local codes. If outside of specified tolerance, make adjustments prior
to making the finish weld.
