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

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 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).

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.
June 2016
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.
3. To avoid serious burns, allow the mounting hardware to cool before
continuing.

3.0 Install isolation valve
1. Thread the guide nipple into the mounting.
2. Thread the isolation valve onto the guide nipple. 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 valve is located in line with the rods.

4. Drill the hole into the pipe wall in accordance with the instructions provided
by the drilling machine manufacturer (use Table 2 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.
6.0 Mount the Rosemount Annubar Assembly
1. Install the complete Flo-Tap assembly (fully retracted) onto the isolation valve
by threading the close nipple into the valve using the proper thread sealant
compound.
2. Rotate the Flo-Tap assembly until the flow arrow on the head aligns with the
direction of flow.
3. Ensure the vent valves are closed before proceeding.
4. Quickly open and close the isolation valve to pressurize the sensor and identify
any leak points in the installation. Use extreme caution if the flowing medium
is steam or caustic.
5. Check the entire installation for leakage. Tighten as required to stop any
connection from leaking.
6. Repeat steps 4 and 5 until there is no leakage.
a. If Flo-Tap comes equipped with the gear drive option, place the Polyvinyl
chloride (PVC) protector rod assembly over the drive rods and attach to
gear drive with supplied hardware.

Note
Rosemount 485 Annubar Flowmeter have the potential to carry a large amount of weight at
a great distance from the piping, necessitating external support. The support plate has
threaded holes to assist in supporting the Rosemount 485.

8.1 Transmitter mounting, direct mount head with valves
It is not necessary to retract the Rosemount Annubar when direct mounting a
transmitter with valves.
1. Place PTFE O-rings into grooves on the Rosemount Annubar head.
2. Align the high side of the transmitter to the high side of the sensor (“Hi” is
stamped on the side of the head) and install.
3. Tighten the nuts in a cross pattern to 384 in-lb (43 N-m).

8.2 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 transmitter are connected to the
sensor by means of impulse piping, which allows service flow 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. (1 mm) is recommended. 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 transmitter.

Top mounting for steam service
Top mounting for steam applications is an appropriate mounting option in many
cases. Consult Rosemount Customer Central instructions regarding steam on top
mounting. 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.

9.0 Retracting the Rosemount Annubar Assembly
9.1 Standard drive (M)
1. Rotate the drive nuts counter-clockwise (as viewed from the top). The nuts
must be loosened alternately, about two turns at a time, to prevent binding
caused by unequal loading.
2. Continue this procedure until the rod end nuts are against the packing body
mechanism.
9.2 Gear drive (G)
1. Remove the drive lock pin.
2. Rotate the crank counter-clockwise. If a power drill with an adapter is used, do
not exceed 200 rpm.
3. Retract until the rod end nuts are against the gear box mechanism.
