correct position.
3.2.2.6 Align the sensor horizontally
The sensor must be aligned horizontally to make sure that the sensor is centered over
the flow. If the pipe is not level and has a slope of 2 degrees or more, align the sensor to
be parallel with the surface of the water.

1. Remove the paper backing from the bubble level and attach the level to the sensor

2. Loosen the clamps and tap the frame into position.
3. Tighten both clamps and measure the frame position to make sure it is at the correct
position.
