  1. Gear Drive Flo-tap Installation Instructions Quick Installation Guides: 00825-0400-4809 rev. EA – 485 Flanged Flo-tap 00825-0500-4809 rev. DB – 485 Threaded Flo-tap 00825-0200-4585 rev. AA – 585 Flanged Flo-tap

  2. Nomenclature Instrument Connections Lift Rings Top Plate Gear Drive Plate Gear Box Rod Protectors Full Port Isolation Valve

  3. Weld the Mounting Hardware Onto the Pipe Threaded Flo-tap Flanged Flo-tap

  4. 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

  5. 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

  6. 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 485 585

  7. 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)

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

  9. Attached the Full Port Valve to the Mounting Hardware Threaded Flo-tap First, thread the guide nipple into the mounting then thread the valve Flanged Flo-tap 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

  10. Verify the ODV Dimension The ODV is the dimension from the outer diameter of the pipe to the top of the valve

  11. Drill the Hole by Using a Hot Tap Drilling Machine Guide Ring in Rosemount Supplied Mounting Hardware Tag with correct drill hole size attached to the Annubar

  12. After the Hole is Drilled, Retract the Drill Past the Valve and Close the Valve Vent drilling machine and remove the per manufacturers 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

  13. Attach the Fully Retracted Flo-tap Assembly to the Valve Threaded Flo-tap

  14. Attach the Fully Retracted Flo-tap Assembly to the Valve Flanged Flo-tap – Use a hoist strap and crane if needed

  15. Quickly Open and Close the Valve to Pressurize the Annubar, Check for Leaks

  16. If Leaks are Present, Tighten the Packing Gland Nuts

  17. Attach Rod Protectors

  18. 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 insertion. Gear Drive Plate Top Plate Top Plate and Gear Drive Plate should remain parallel during insertion Shown twisted ~90° from Gear Drive Plate

  19. If Using a Drill for Insertion, Attach the Drill to the Insertion Mechanism • Do not exceed 200 RPM on the Drill

  20. Insert the Annubar Stop the drill and crank by hand once the orange stripes reach the Gear Box Plate

  21. Continue to Insert the Sensor with the Manual Crank

  22. 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

  23. Turn the handle an additional ½ turn to ensure it is fully inserted

  24. Insert the Drive Lock Pin to Secure the Sensor in Place

  25. 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.

  26. Retighten the Packing Gland Nuts
