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 HardwareThreaded Flo-tapFirst, thread the guide nipple into the mounting then thread the valve

Flanged Flo-tap

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

Drill the Hole by Using a Hot Tap Drilling Machine

Tag with correct drill hole size attached to the Annubar

Guide Ring in Rosemount Supplied Mounting Hardware

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

and site proceduresThreaded 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 Assembly to the Valve

Threaded 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 InsertionDuring 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

PlateTop Plate

Shown twisted ~90° from Gear Drive Plate

Top Plate and Gear Drive Plate should remain parallel during insertion

If Using a Drill for Insertion, Attach the Drill to the Insertion Mechanism Do not exceed

200 RPM on the Drill

Insert the AnnubarStop 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 turnThis gives an indication of full insertion if the Annubar is retracted at a later date.

Retighten the Packing Gland Nuts
