IP68 Waterproof Flow Velocity Doppler Water Flow Meter Sensor High Precision

Doppler Flow Velocity/water Level/flowmeter Features High Precision, High Reliability, RS485 Output, Simple Installation And Maintenance-free

Acoustic Doppler point flowmeter/flowmeter, suitable for scenarios such as rivers, open channels, and pipelines, is used for online monitoring of flow velocity, water level, temperature, instantaneous flow rate, and cumulative flow rate in water areas.
The instrument measures flow velocity by the ultrasonic Doppler principle and water level by the ultrasonic time difference method or static pressure method. The flow rate is calculated by setting the cross-section. The Doppler flowmeter features a compact structure, no rotating parts, long service life, simple operation and maintenance-free operation. It is widely used in scenarios such as sponge cities, water supply and drainage networks, black and odorous water bodies, natural rivers, open channels, reservoirs, flow field analysis in scientific research, and liquid level detection.
