NOTE
• For gas service, multiply values from Table 1 by 1.5.
• 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.

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. The preferred orientation for air or gas is flow down, but upwards
flow is acceptable. For steam applications, a 90° spacer will be added
to provide water legs to ensure the transmitter stays within
temperature limits.

STEP 2: WELD MOUNTING HARDWARE
NOTE
Rosemount-supplied mounting includes critical alignment 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 thread-o-let on the pipe,
gap 1/16 in (1.5 mm), and place four 1/4-in. (6-mm) tack welds at 90°
increments.
2. Check alignment of the mounting both parallel and perpendicular to
the axis of flow (see Figure 7). 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.

STEP 3: INSTALL ISOLATION VALVE
1. Thread the guide nipple into the mounting.
2. Thread the isolation valve onto the guide nipple. Ensure that 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 8). (Note: Interference will
occur if valve is located in line with the rods.)
Figure 8. Isolation Valve Orientation
STEP 4: MOUNT DRILLING MACHINE
Drilling Machine is not provided with assembly.
1. Determine the sensor size based on the probe width (see Table 2).
2. Mount the drilling machine to the isolation valve.
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 2 to
select the proper drill bit for the sensor being used).
5. Retract the drill fully beyond the valve.

STEP 5: REMOVE DRILLING MACHINE
1. Verify that 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.
STEP 6: MOUNT THE ANNUBAR
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 that the vent valves are closed before proceeding.
4. Quickly open and close the isolation valve to pressurize the 485
Annubar. During installation, there is a potential for leakage at the
packing. 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. Repeat steps 4 and 5 until there
is no leakage
a. If Flo-Tap comes equipped with the gear drive option, place the
PVC protector rod assembly over the drive rods and attach to
gear drive with supplied hardware.
NOTE
Flo-Tap 485 Annubars 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 485 Annubar.

STEP 8: MOUNT THE TRANSMITTER
Transmitter Mounting, Direct Mount Head with Valves
It is not necessary to retract the Annubar when direct mounting a
transmitter with valves.
1. Place Teflon®(PTFE) O-rings into grooves on the face of 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 400 in•lb (45 N•m).
Transmitter Mounting, Direct Mount Head without Valves
1. Place Teflon (PTFE) O-rings into grooves on the face of head.
2. Orient the equalizer valve(s) so they are easily accessible. Install a
manifold with the smooth face mating to the face of the head.
Tighten in cross pattern to a torque of 400 in•lb (45 N•m).
3. Place Teflon (PTFE) O-rings into grooves on the face of the
manifold.
4. 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.
5. Tighten the nuts in a cross pattern to 400 in•lb (45 N•m).
Transmitter Mounting with Remote Mount Head
Temperatures in excess of 250 °F (121 °C)at the electronics will
damage the transmitter. Remote mounted electronics are connected to
the sensor by means of impulse piping, which allows service flow
temperatures to decrease to a point where the electronics are 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 1/2in. (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.

September 2003 Threaded Flo-Tap 485 Annubar
STEP 8 CONTINUED...
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 electronics) for liquid and steam
applications
• Slope upward (toward the electronics) for gas applications.
2. For applications with temperature below 250 °F (121 °C), impulse
piping should be as short as possible to minimize temperature
changes. Insulation may be required.
3. For applications above 250 °F (121 °C), impulse piping should
have a minimum length of one foot (0.3048 m) for every 100 °F
(38°C) temperature increase over 250 °F (121 °C). Impulse piping
must be non-insulated to reduce fluid temperature. Any threaded
connections should be checked after the system reaches the
intended temperature because connections may come loose with
contraction and expansion caused by temperature change.
4. Outdoor installations for liquid, saturated gas, or steam may require
insulation and heat tracing to prevent freezing.
5. When impulse piping is longer than six feet (1.8 m) the high and
low impulse lines must be positioned together to maintain equal
temperature. They must be supported to prevent sagging and
vibration.
6. Impulse lines should be positioned in protected areas or against
walls or ceilings. Use appropriate pipe sealing compound rated for
the service temperature on all threaded connections. Do not place
the impulse piping near high temperature piping or equipment.
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 electronics.
