Open Channel Flowmeter Monitoring Water

Product Detail

Sensor installation

Ultrasonic probe was install on the top of the flume,  measuring the water level in the flume. Transmitter calculate the open channel instantaneous flow rate according to the water level and flume type and get the value of cumulative flow.
