- RDV radar Doppler velocity and discharge meter
◆ Measurement principle—08This is a non-contact flow measurement method. The Doppler radar integrates a microstrip antenna, RF circuit, and signal processing module, enabling direct acquisition of fluid surface velocity information. Thevelocity radar measures based on the Doppler effect generated by the movement of water surface waves.It is recommended to install the velocity sensor module facing the upstream direction. When the water flowapproaches the velocity sensor module, a positive velocity will be displayed. If there are highly reflective obstructions such as metal in the radar's emission direction, it will severely affect the radar's measurement performance.The water level radar can obtain water level data, which, when combined with the base data, allows forthe calculation of the wetted cross-sectional area. Multiplying this by the flow velocity data yields the discharge data.◆ Main Features▶ Measurement parameters: flow velocity, flow rate, water level,
cross-sectional area, etc.;▶ The radar antenna forms a 35° angle with the horizontal plane; The entire device is compact and lightweight;▶ Electrical interface: adopts aviation Utetheisa Kong connector;▶ Two specifications of water level radar are available depending on the installation location;▶ Comes with a universal stainless steel bracket and leveling bubble for easy attitude adjustment during installation;▶ The product can optionally include a built-in 4G full-network wireless module for direct data upload via the public network;
▶ Awards: multiple patents and software copyrights;▶ Awarded: "Inspection Report" by East China Hydrological Instrument Testing Center;▶ Awarded: "Test Report" by Central-South Hydrological Instrument Testing Center;▶ Selected for the "National Water Resources System Key Procurement Catalog for Bidding Products"◆ Application scenariosHydrology, water resources, environmental protection, and water affairs departments conduct velocity and flow measurements in rivers, channels, and other water bodies. -
