Installation
Step 5: Remove the drilling machine
Follow these steps to remove the drilling machine:
1. Verify the drill has been fully retracted past the valve.
2. Close the isolation valve to isolate the process.
3. Bleed drilling machine pressure and remove.
4. Check isolation valve and mounting for leakage.
Step 6: Mount the Annubar sensor
1. Install the complete Flo-Tap assembly (fully retracted) onto the isolation valve by
threading the close nipple into the valve using the proper thread sealant compound.
2. Rotate the Flo-Tap assembly until the flow arrow on the head aligns with the direction
of flow in the pipe.
3. Ensure the vent valves are closed before proceeding to the next step.
4. Quickly open and close the isolation valve to pressurize the Annubar sensor. Use
extreme caution if the flowing medium is steam or caustic.
5. Check the entire installation for leakage. Tighten as required to stop any connection
from leaking. Repeat steps 4 and 5 until there is no leakage.
a. If the Flo-tap comes equipped with the gear drive option, place the PVC protector
rod assembly over the drive rods and attach to the gear drive with the supplied
hardware.
Note
Flo-Tap Annubar sensors have the potential to carry a large amount of weight at a great distance
from the piping, necessitating external support. The support plate has threaded holes to assist
in supporting the Annubar sensor. Threaded holes (
3
/8 in.-16 UNC) are provided on the support
plate for external support.
