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 the Rosemount 485 Annubar Reference Manual for more
instruction. This manual is also available electronically on EmersonProcess.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.

Note
Consult the factory for instructions regarding use in square or rectangular
ducts.
“In plane A” means the bar is in the same plane as the elbow. “Out of plane A”
means the bar 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 Table 1 applies to gate, globe, plug, and other throttling valves that
are partially opened, as well as control valves.
1.1 Misalignment
Rosemount 485 Annubar installation allows for a maximum misalignment of 3°.

Quick Start Guide
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). See “Install isolation valve” on
page 9 for remote mounted transmitter recommendations.
Figure 3. Gas
s
Figure 4. Liquid and Steam
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.

Note
Due to the weight of the Flo-Tap mounting hardware, external support may be needed for
vertical orientation applications and horizontal orientation applications that are installed
outside of the recommended zones.
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 flanged assembly on the pipe, 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 toTable 2 and adjust the gap as
necessary.
Table 2. Flange Sizes and Outer Diameter to Flange (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 8). 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.

A. ODF
B. Tack welds
3. To avoid serious burns, allow the mounting hardware to cool before
continuing.
3.0 Install isolation valve
1. Position the isolation valve onto the mounting flange. Ensure the valve stem is
positioned so that when the Flo-Tap is installed, the insertion rods will straddle
the pipe and the valve handle will be centered between the rods (see Figure 9).
Note
Interference will occur if the valve is located inline with the rods.
2. Fasten the isolation valve to the mounting using gasket, bolts, and nuts.

4.0 Mount drilling machine and drill hole
Drilling machine is not provided with assembly.
1. Determine the sensor size based on the sensor width (see Table 3).
Table 3. Sensor Size/Hole Diameter Chart
2. Mount the drilling machine to the isolation valve.
A. Isolation valve is fully open when inserting drill
B. Pressure drilling machine
C. Isolation valve is fully closed after withdrawing drill
3. Open the valve fully.
4. Drill the hole into the pipe wall in accordance with the instructions provided
by the drilling machine manufacturer (use Table 3 to select the proper drill bit
for the sensor being used).
5. Retract the drill fully beyond the valve.
5.0 Remove drilling machine
1. Verify the drill has been retracted past the valve.
2. Close the isolation valve to isolate the process.
3. Bleed drilling machine pressure and remove.
4. Check isolation valve and mounting for leakage.
