2.4.5 Insertion Procedure for Flow Meters with No Insertion Tool (Packing Gland Connection)
1. Calculate the required sensor probe insertion length.
2. Fully retract the stem until the sensor head is touching the bottom of the stem housing.
Remove the two top stem clamp nuts and loosen two stem clamp bolts. Slide the stem
clamp away to expose the packing gland nuts. Loosen the two packing gland nuts.
3. Align the sensor head using the sensor alignment pointer. Adjust the alignment pointer
parallel to the pipe and pointing downstream.
4. Insert the sensor head into the pipe until insertion length, I, is achieved. Do not force
the stem into the pipe.
5. Tighten the packing gland nuts to stop leakage around the stem. Do not torque over 20
ft-lbs.
6. Slide the stem clamp back into position. Torque stem clamp bolts to 15 ft-lbs. Replace
the stem clamp nuts and torque to 10-15 ft-lbs.
!
WARNING
The line pressure must be less than 50 psig for installation.
!
CAUTION
The sensor alignment pointer must point downstream, in the direction of flow.
