2.2 Sensor Position
When installing the sensor in a horizontal pipe run the optimum position is at 0° or 180°, assuming the line is always full and contains no solids.
Air pockets or sediment in the line will disturb the rotation of the paddlewheel, causing inaccuracy in the calibration. Installing the sensor at an angle
