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.
