Sensor position after change in profile
For horizontal/level pipes, avoid mounting the sensors at the top or bottom of the
pipe. Risk exists for sedimentation/silt or air bubbles resulting in measurement
failure. ADS recommends mounting the sensor at a location -45° to +45° from the
center horizontal axis of the pipe.

Recommended installation angles
Vertically laid pipes do not carry the same risk of swamping/air; therefore, any
mounting location may be selected.
However, an accurate and reliable measurement can be performed only in full pipes.
For this reason, do not install sensors in downpipes or at the highest point of the
pipeline.
