Product Introduction:
The SCJ-LL21 drone-mounted radar velocity meter is a device that uses the Doppler effect of electromagnetic waves to measure water flow velocity. It emits 24GHz electromagnetic waves and irradiates the surface of the water body. The water body backscatters the electromagnetic waves to obtain echoes, and measures the Doppler frequency shift of the echoes to obtain the surface velocity of the water body. The internal integrated signal processor, acquisition transmission power supply port system, and proprietary velocity calculation algorithm can quickly and accurately calculate the water flow velocity, and no calibration is required, and there is no drift. The water flow velocity and flow monitoring system relies on advanced flight platforms, flow velocity, and water level radars, and can intelligently monitor the water flow velocity. It has the characteristics of flexibility, low cost, rich functions, simple operation, and low risk, and can provide strong support for water flow velocity and flow monitoring.
