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.

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.

6.0 Mount the Rosemount Annubar Assembly
1. Align the flow arrow on the head with the direction of flow.
2. Use the supplied gaskets and flange bolts to fasten the Flo-Tap assembly to the
isolation valve.
3. Tighten the nuts in a cross pattern to compress the gasket evenly.
4. Ensure the vent valves are closed before proceeding.
5. Open and close the isolation valve to pressurize the Rosemount 485 Sensor
and identify any leak points in the installation. Use extreme caution if the
flowing medium is steam or caustic.
6. Check the entire installation for leakage. Tighten as required to stop any
connection from leaking.
7. Repeat step 5and 6until there is no leakage.
Note
Rosemount 485 Annubar 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 Annubar.

Quick Start Guide
7.0 Insert the Rosemount Annubar Sensor
7.1 Standard drive (M)
1. Open the isolation valve fully.
2. Rotate the drive nuts clockwise (as viewed from the top). The nuts must be
tightened alternately, about two turns at a time, to prevent binding caused by
unequal loading.
3. Continue this procedure until the tip of the sensor firmly contacts the
opposite side of the pipe.
a. The orange stripes are visual indication of when the sensor is approaching
the opposite side wall.
b. As the orange strip approaches the support plate, place a finger above the
packing gland while cranking. When movement stops, the sensor is in
contact with the opposite side wall.
c. Turn the handle an additional 1/4to 1/2turn to secure the sensor.
7.2 Gear drive (G)
1. Open the isolation valve fully.
2. Rotate the crank clockwise. If a power drill with an adapter is used, do not
exceed 200 rpm.
a. Continue rotating the crank until the sensor firmly contacts the opposite
side of the pipe. The orange stripes are visual indication of when the sensor
is approaching the opposite side wall.
b. As the orange stripes approach the support plate, remove the power drill
and continue cranking manually. Place a finger above the packing gland
while cranking. When movement stops, the sensor is in contact with the
opposite side wall.
c. Turn the handle an additional 1/4to 1/2turn to secure the sensor.

8.0 Mount the Transmitter
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 transmitters are connected to the
sensor by means of impulse piping, which allows process 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 1/2-in. (12 mm) outer diameter stainless steel tubing
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
This orientation can be used for any steam temperature. However, it is required
for installations above 600 °F (315 °C). 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.
