Overview
Principle of portable Doppler flowmeter: When the ultrasonic sound source and the observer make relative motion, the frequency received by the observer will be different from the frequency of the ultrasonic sound source. Therefore, compared to the small particles and bubbles that move with water in ultrasonic transducers, the receiving frequency of the transducer will also change, and it will increase with the increase of suspended motion speed in water. Therefore, the Doppler frequency shift can be measured, and the flow velocity at the point where the Doppler flowmeter is located can be measured. Mainly used for irrigation open channels, municipal sewage pipelines, hydrological basins, and other occasions.

1、 Product Introduction
Portable Doppler flowmeterPrinciple: When the ultrasonic sound source and the observer make relative motion, the frequency received by the observer will be different from the frequency of the ultrasonic sound source. Therefore, compared to the small particles and bubbles that move with water in ultrasonic transducers, the receiving frequency of the transducer will also change, and it will increase with the increase of suspended motion speed in water. Therefore, the Doppler frequency shift can be measured, and the flow velocity at the point where the Doppler flowmeter is located can be measured. Mainly used for irrigation open channels, municipal sewage pipelines, hydrological basins, and other occasions. Especially suitable for low water level situations, it can work when the water level exceeds 15 centimeters. In regular pipelines and channels, the water depth can be measured by the pressure sensor on the flowmeter, and the flow velocity can be measured by the ultrasonic sensor, which can easily calculate the flow rate.
The product measures flow velocity based on the principle of ultrasonic Doppler effect, and can measure water level and water temperature through pressure sensors. The shell is made of PVC plastic, which can effectively prevent water and seal. The shell is 25 centimeters long, 3 centimeters high, and 7 centimeters wide. Flow velocity can be measured in open channels and larger pipelines.
