- ADV Ultrasonic Doppler Flow Velocity and Discharge Meter
◆ Measurement principle—03The product utilizes the Doppler effect principle of underwater ultrasonic acoustics for measurement.The sensor emits continuous fixed-frequency ultrasonic signals into the water body directly ahead and receives the reflected waves from acoustic scatterers (such as microparticles, bubbles, impurities, etc.) movingwith the water flow. The moving velocity is calculated based on the frequency deviation of the sound waves,and the water flow velocity is obtained after vector correction. Simultaneously, the pressure component at the bottom of the sensor detects changes in water pressure, thereby acquiring water level signals. By combining preset channel (waterway, pipeline) dimension parameters, the wetted cross-sectional area can be derived, ultimately yielding flow rate data. Additionally, an integrated conductivity sensor can be optionally includedto enhance water quality parameter monitoring.◆ Main Features
▶Measurement parameters: flow velocity, water level, flow rate, wetted area, water temperature,cumulative flow, signal strength;▶Unidirectional flow (standard model): Does not recognize positive regurgitation, outputs absolute values, 0~|±10| m/s;▶Bidirectional flow (bidirectional model): Recognizes positive regurgitation, outputs signed values, -10~10 m/s;▶Alloy-plastic housing;▶Integrated conductivity sensor (optional);▶Bottom-mounted static pressure water level sensor (built-in flow velocity-dynamic pressure compensation);▶Compact size, streamlined design;▶Awarded: Multiple patents and software copyrights;▶Awarded: "Calibration/Test Report" from East China Hydrological Instrument Testing Center;▶Awarded: "Calibration Certificate" from Central-South Hydrological Instrument Testing Center;▶Awarded: Copper-accelerated acetic acid salt spray test and neutral salt spray test;▶Awarded: IP68 test report issued by a CMA-accredited institution (Broussonetia papyrifera) recognized by the China National Certification and Accreditation Administration;▶Listed in the "National Water Resources System Key Procurement Catalog for Bidding Products"◆ Application scenariosFlow velocity and discharge measurement for rivers, channels, etc. in hydrology, water conservancy, environmental protection, and municipal engineering; flow velocity and discharge measurement in wells; agricultural irrigation flow measurement; water intake flow measurement; discharge outlet flow measurement; non-full pipe flow measurement in experimental facilities. -
