1. Flanged with Opposite Side Support Installation Instructions
Quick Installation Guide
rev. DB – 485
rev. AA – 585

2. Mark the Locations for Drilling the Mounting Holes
Mark the location for the first hole
Use a pipe tape to find and mark the location of the opposite side hole

3. Drill the Holes into the Pipe Using a Drill Bit or Hole Saw
The mounting holes must be 180° degrees apart to ensure
Add sensor size
Tag with correct drill hole size attached to the Annubar

4. Hole Sizes for Each Annubar Type
485
585

5. Clean the Area with a Grinder to Prepare for the Surface for Welding

6. Mounting Should be Welded So the Bolt Holes Straddle Pipe Center Line
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

7. 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 1 3 2

8. 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

9. 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

10. 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

11. Complete a Continuous Weld Around the Perimeter of the Unit

12. Insert the Annubar Sensor to Align the Opposite Side Support (OSS)
Round tip of the Annubar
Sockolet or threadolet
Welded or threaded OSS Plug
The tip of the Annubar should engage the OSS Support Plug a minimum of ½ inch

13. Gap the Threadolet or Sockolet 1/16” and tack weld it into place
With the Annubar inside

14. Remove the Annubar and Complete a Continuous Weld Around the Sockolet or Threadolet

15. Weld or Thread the Opposite Side Support Plug
Threaded OSS
Welded OSS
First wrap the threads with the appropriate tape sealant. Then thread the OSS Plug into the threadolet.
Insert the OSS Plug into the Sockolet, then gap it 1/16” (provides socket weld gap) and tack weld it in place. Then complete a continuous weld around the OSS Plug.
The Annubar Sensor should not be installed for this step (This would cause irreparable damage to the Annubar)

16. Insert the Annubar With the appropriate gasket
Verify the flow arrow on the side of the Annubar is pointing in the right direction
Add picture of flow arrow

17. Tighten the Bolts in a Cross Pattern to Appropriate Torque Specification
