 Doppler flow meter/flow meter is suitable for flow measurement in open channels and partially flled pipes.The instrument uses the ultrasonic Doppler principle to measure the flow velocity, the ultrasonic time difference method measures the liquid level, and calculates the flow rate by setting the cross section. Doppler flow meter has the characteristics of compact structure, no rotating parts, long life, simple use and maintenance-free. Compared with the traditional rotor flow meter and propeller flow meter, the Doppler flow meter has the advantages of high accuracy, no entanglement of rotating parts, less affected by water flow disturbance, convenient installation and operation, standard communication protocol, and the advantages of measuring water depth and temperature
