Dayu Electronics Ultrasonic Doppler Flowmeter Suitable for Velocity and Flow Measurement in Open Channels and Rivers
The ultrasonic Doppler flowmeter utilizes the Doppler effect of sound waves propagating in a fluid. By measuring the Doppler frequency shift of sound waves scattered by moving particles in the fluid, the fluid velocity is obtained. Combined with the integrated pressure-type water level gauge and using the velocity-area method, it can measure the liquid flow rate. This instrument is suitable for flow velocity and flow rate measurement in open channels, rivers, and other situations where constructing a standard cross-section is difficult, as well as for various full-pipe and non-full-pipe open channel flow measurements.
