Ultrasonic Water Flow Meter

The open channel flow meter level sensor is mounted on the top of the flume, and ultrasonic wave is transmitted by the probe to the surface of the monitored material. Instead of using mass or volumetric data to determine the rate of flow of a substance, open channel flow meters monitor the relationship between the depth of the liquid and the flow rate.
