Ultrasonic Open Channel Flow Meter

The transit time corresponds to the distance between the face of the sensor and the surface of the water.

Ultrasonic open channel flow meter. Ultrasonic flow meters measure the level in a channel by transmitting a pulse of sound from the face of the sensor to the surface of the flow stream and measuring the time for the echo to return. Principle time transit flow meter. All the measurements are available over modbus rtu and can be logged. The multiranger and hydroranger series consist of versatile single and multi vessel ultrasonic level controllers.

An economical open channel flow meter isonic 4000 measures level flow rate and total volume of water flowing through weirs and flumes. Ultrasonic flow meters that use the doppler shift are called reflection or doppler flow meters. Open your mind to our open channel flow portfolio. Open channel flow meters measure level flow rate and total volume of water flowing through weirs flumes channels and partially filled pipes.

The flow meters use a non contact level sensor to detect the water level and then calculates the flow rate and volume using the manning equation and characteristics of the channel. Non contacting velocity measurement is also available for use in open channel flow for velocity x area measurement. Ultrasonic flow meters measure the difference between the transit time of ultrasonic pulses propagating with and against the flow direction. The third type is the open channel flow meter.
