1. Location of Fitting

Recommended sensor upstream/
downstream mounting requirements.

2. Sensor Mounting Position

• Horizontal pipe runs: Mount sensor in the upright (0°) position for best overall performance. Mount at a
maximum of 45° when air bubbles are present. Do not mount on the bottom of the pipe when sediments
are present.
• Vertical pipe runs: Sensor must be mounted in lines with UPWARD flow only.
