Chapter 2. Installation
2.3.2 Installing Flow Meters with a Compression Connection (cont.)
CAUTION!
WARNING!
Refer to Figure 16 on page 23 and complete the following steps:
1. Refer to Figure 15 on page 22 and calculate the required sensor probe insertion length for your system.
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 flow meter assembly into the process connection. Use PTFE 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.
IMPORTANT: After the compression fitting is tightened, the position is permanent.
24
The sensor alignment pointer must point downstream, in the direction of flow.
To avoid serious injury, DO NOT loosen the compression fitting under pressure.
