3.3.2 Installation for screwed connections:
Step 1 -
Tap the pipe, the hole should be at least 50 mm (2") in diameter, nominally
50 mm (2") in diameter.
Step 2 -
Weld thread-o-let to pipe.
Step 3 -
Important
- Attach the tap check tool to the end of the flowmeter stem before
proceeding:
-
Attach the flowmeter to the thread-o-let.
-
Verify that the bleed valve is closed.
-
Use the orientation levers to manually lower the tap check tool into the pipe
and then retract the tap check tool completely.
-
Remove the flowmeter from the thread-o-let and inspect the tap check took
for damage.
-
If any has occurred, check the installation for possible clearance problems.
Step 4 -
Remove the tap check tool and attach the turbine sensor (rotor assembly) to the
end of the stem.
-
Verify that the screw and safety wire on the rotor assembly are correctly
installed.
-
Reconnect the flowmeter to the thread-o-let.
-
Verify that the bleed valve is closed.
-
Use Teflon tape or PST on the threads to improve the seal and prevent seizing.
-
If the flowmeter is supplied with a pressure transmitter, open the bleed valve.
-
Do not lower the turbine sensor into the pipe before calculating the proper
insertion depth.
