Chapter 2 Installation Series 24-HP Instruction Manual
2-16 IM-24-HP
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.
