Drill the Hole into the Pipe Using a
Drill Bit or Hole Saw
Tag with correct drill hole
size attached to the Annubar
Clean the Area with a Grinder to
Prepare for the Surface for Welding
Mounting Should be Welded So the
Bolt Holes are Parallel to Pipe

The mounting
hardware should be
gapped 1-/16th inch
for welding
– Use weld rod to do this

It should also be
centered over the
drilled hole
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
Complete a Continuous Weld Around
the Perimeter of the Unit
Using a Gasket, Install the Flange on
the Mounting Hardware
Tighten the Studs in Nuts in a Cross
Pattern Until Appropriately Torqued
Insert Studs into the Flange-lok Body
Mark the End of the Sensor With a
Felt Tip Marker
Do not mark if order with special cleaning
(Option Code P2, PA)
Insert the Flowmeter Until the Tip
Contacts the Opposite Side Pipe Wall
Rotate Annubar back and forth.
