Doppler flowmeter is measured using the principle of ultrasonic Doppler. Depending on the application scenario, it can also be referred to as river flowmeter, sewer flowmeter, channel flowmeter, farmland irrigation flowmeter, non full pipe flowmeter, etc. It does not require the installation of pipe segment sensors like electromagnetic flow meters, nor does it require the use of interception devices, nor does it require the installation of fixed weirs to control the flow of water from a fixed outlet. Doppler flowmeter can measure both clear and turbid water, and can also measure reverse flow velocity.

Open channel flow meter/Doppler flow meter is used to measure the flow rate of a fluid in a non full tubular open channel, in a free water surface state of natural flow, known as open channel flow detection. The measuring tank in a non full pipe state is called an open channel, and the instrument used to measure the fluid flow in the open channel is called an open channel flowmeter/Doppler flowmeter. Ultrasonic open channel flowmeter/Doppler flowmeter consists of three parts: ultrasonic level gauge, measuring tank, and flow accumulator.
