YSQD02Ultrasonic Flowmeter
Wall-Mounted Ultrasonic Doppler Flowmeter
Wall-mounted ultrasonic Doppler flowmeter measures liquid level (0–10 m), flow velocity (0–5 m/s), and accumulated flow in open channels, non-full pipes, rivers, sewers, and irrigation channels. It provides 1% accuracy and outputs via 4–20 mA and RS485/Modbus. Typical uses include urban drainage, river hydrological monitoring, and irrigation informatization.
