Description

[0002] Most of Northeast my country is located in high latitudes, and the ambient temperature is low in winter, reaching about -20℃. In this harsh natural environment, the river water under the ice contains ice and water mixtures such as icicles, which interfere with the measurement. The ultrasonic Doppler velocity measurement method in the prior art uses the Doppler effect of ultrasound to measure the flow velocity of water under the ice. An ultrasonic transducer is used to continuously emit ultrasound of a certain frequency, and another transducer receives the reflected ultrasound. The velocity of the river water is calculated by the size of the Doppler frequency transplantation and the propagation speed of ultrasound in water. This solution can measure liquids with a large flow rate and has a high resolution for the velocity.
