\nObservation principle: the instrument is a mechanical current meter, which calculates the fluid velocity according to the speed of water turbine.

When the channel flow is stable, the observation frequency of the channel average velocity and water level is 1 time / hour; when the channel flow is stable, the observation frequency of the channel average velocity and water level is 2 times / hour; when the channel flow changes greatly, the channel average velocity and water level are observed every time.
