RG-30+C: Combined non-contact water velocity and level radar sensor

RG-30+C: Combined non-contact water velocity and level radar sensor

RG-30+C is a combined radar sensor for continuous, non-contact measurement of water level and surface velocity in rivers and channels. It uses radar transit time and Doppler frequency shift to provide real-time data for discharge monitoring.
