3.8.1 Insertion procedure for meters with a compression connection
Fig. 7 Flowmeter with compression type fitting
Caution!
The sensor alignment pointer must point downstream, in the direction of flow.
Warning!
To avoid serious injury, DO NOT loosen the compression fitting under pressure.
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.
Slightly tighten the compression nut to prevent slippage.
3.
Bolt or screw the flowmeter assembly into the process connection. Use Teflon tape or
pipe sealant to improve the seal and prevent seizing on NPT styles.
4.
Hold the meter securely while loosening the compression fitting. Insert the sensor into
the pipe until the calculated insertion length, I, is measured between the base of the
enclosure adapter and the top of the stem housing, or to the raised face of the flanged
version. Do not force the stem into the pipe.
5.
Align the sensor head using the sensor alignment pointer. Adjust the alignment pointer
parallel to the pipe and pointing downstream.
6.
Tighten the compression fitting to lock the stem in position.When the compression fitting
is tightened, the position is permanent.
