Weld the Mounting Hardware Onto
the Pipe
Threaded Flo-tap
Flanged Flo-tap
Tack Weld the Mounting Hardware
with 4 Equal Length Tacks

Tack weld anywhere on
the mounting hardware

Then again directly across
from the first tack weld

Then on the other 2 sides

Check to See that the Mounting
Hardware is Level and Square

If it’s not, use a
rubber mallet to
lightly adjust the
hardware and
recheck
Verify that the
ODF Dimension
Matches What is
Listed in the QIG
The ODF is the
dimension from outside
pipe diameter to face
of flange

Verify that the ODF Dimension
Matches What is Listed in the QIG
The ODF is the
dimension from
outside pipe diameter
to face of flange
For Threaded Flo-tap the dimension
from the pipe OD to the top of the
threadolet is called LMH:
485 Sensor Size 1: 1.38-in. (35 mm)
485 Sensor Size 2: 1.56-in. (40 mm)
485 Sensor Size 3: 2.06-in. (52 mm)
Complete a Continuous Weld Around
the Perimeter of the Unit
Attached the Full Port Valve to the
Mounting Hardware
Threaded Flo-tap
Flanged Flo-tap
First, thread the guide nipple into the
mounting then thread the valve
ODV
The valve stem should be in-line with the pipe
so it will not interfere with the insertion rods
The valve must be a full port valve to allow the
Annubar to pass through the valve into the pipe
Verify the ODV Dimension
The ODV is the dimension from the outer diameter of the pipe to the top
of the valve

and site procedures
Threaded Flo-tap
Flanged Flo-tap
Remember that the hot tap drilling
machine is under pressure and
exposed to the process fluid
Attach the Fully Retracted Flo-tap

Attach the Fully Retracted Flo-tap
Assembly to the Valve
Flanged Flo-tap – Use a hoist strap and
crane if needed
Quickly Open and Close the Valve to
Pressurize the Annubar, Check for Leaks
If Leaks are Present, Tighten the
Packing Gland Nuts
Attach Rod Protectors
Caution During Insertion
During insertion, the top plate can twist due to the
torque of the gear drive. To keep the Annubar
from twisting, hold the top plate in place during
Gear Drive
insertion.

Top Plate and Gear Drive
Plate should remain

If Using a Drill for Insertion, Attach
the Drill to the Insertion Mechanism

Do not exceed
200 RPM on the
Drill
Insert the Annubar
Stop the
drill and
crank by
hand once
the orange
stripes
reach the
Gear Box
Plate
Continue to Insert the Sensor with
the Manual Crank
Place a finger above the packing
gland to feel for full insertion

CAUTION: Be
careful if doing
this with steam or
other harmful
fluids

When movement
stops, the
Annubar is fully
inserted
Turn the handle an additional ½ turn
to ensure it is fully inserted
Insert the Drive Lock Pin to Secure
the Sensor in Place
Tighten the Nuts to the Gear Box
Plate and Loosen ¼ turn
This gives
an
indication
of full
insertion if
the
Annubar is
retracted at
a later
date.
Retighten the Packing Gland Nuts
