[0002] Flow velocity detection is the determination of the numerical value and direction of the velocity of water particles. Flow velocity detection is one of the important detection contents in water flow experiments; in steady flow, the time-averaged flow velocity is generally detected; in non-steady flow, the change process of flow velocity over time is detected. For non-steady flow with slow changes (such as tidal currents), the change process of flow velocity can be reflected by detecting the time-averaged flow velocity in a short period of time at regular intervals; for the detection of pulsating flow velocity (whether in steady flow or non-steady flow), the dynamic process of flow velocity change over time must be measured, and the frequency and intensity of flow velocity pulsation must be analyzed.
