Product Description Product DescriptionThe product utilizes the Doppler effect principle of underwater ultrasonic acoustics for measurement.Thesensor emits continuous fixed-frequency ultrasonic signals into the water body directly ahead and receives the waves reflected by acoustic scatterers (such as microparticles, bubbles, impurities, etc.) moving with 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 element 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 cross-sectional flow area can be derived, ultimately yielding flow rate data. Additionally, an integrated conductivity sensor can be optionally included toenhance water quality parameter monitoring.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.Product Parameters1.Measurement parameters: flow velocity, water level, flow rate, wetted cross-sectional area, water temperature, cumulative flow, signal strength; 2.Unidirectional flow (standard model): Does not distinguish between forward/reverse flow, outputs absolute value, 0~|±10| m/s; 3.Bidirectional flow (bidirectional model): Identifies forward/reverse flow, outputs signed value, -10~10 m/s; 4.Alloy-plastic housing; 5.Integrated conductivity sensor (optional); 6.Bottom-mounted static pressure water level sensor (built-in flow velocity-dynamic pressure compensation); 7.Compact size with streamlined design; 8.Awarded: Multiple patents and software copyrights; 9.Awarded: "Calibration/Test Report" from East China Hydrological Instrument Testing Center; 10.Awarded: "Calibration Certificate" from South Central Hydrological Instrument Testing Center; 11.Awarded: Copper-accelerated acetic acid salt spray test and neutral salt spray test; 12.Awarded: IP68 test report issued by CMA-accredited institution of China National Certification and Accreditation Administration; 13.Listed in "National Water Resources System Key Procurement Catalog for Bidding Products"Flow velocity accuracy1%±0.005m/sFlow velocity resolution0 .001m/sDead zone flow velocityUnidirectional flow pattern:0~0.006m/s,Two-way flow payment:-0.03m/s~0~0.03m/sWater level range0-10m,CustomizableWater level accuracy0.2%FS±0.001mWater level resolution0.001mConductivity range/accuracy0~10.000mS/cmWater temperature range/accuracy0~60.0°C/0.5°CWater temperature resolution0.1°CPower supply6~26VDC, typical value: 12VDC, unidirectional flow(55±5mA), bidirectional flow (85±5mA)OutputRS485.MODBUS.RTUOutput dampingSmoothing (flow velocity/flow rate): intelligent algorithm; Intermittent (flow velocity/flow rate): 10 seconds; Inversion (flow velocity/flow rate): 0.02 secondsUltrasonic sensorSingle-point single-beam, 2 MHz, 5° oblique anglePower consumption High-performance mode (5 measurements per second): Unidirectional flow model (55±5 mA), Bidirectional flow model (90±5 mA) Low-power ECO mode (5 measurements every 5 seconds): Unidirectional flow model (20±2 mA), Bidirectional flow model (30±2 mA), CustomizedBase configurationRectangle, circle, trapezoid, ellipse, U-shape, othercustomizations Company Profile Founded in 2007, Fujian Aotai Automation Equipment Co., Ltd. is located in the beautiful Fuzhou, Fujian.
