Doppler ultrasonic open channel sensor

KH.DPL-01 is an advanced Doppler ultrasonic flowmeter that accurately measures flow velocity using the Doppler principle, and water level using either ultrasonic time difference or static pressure methods. It calculates real-time flow by combining measured velocity with the preset channel cross-section. Built-in temperature compensation ensures accurate sound velocity correction under varying environmental conditions.

Key Features
Long service life: IP68 waterproof and anti-corrosion probe for long-term underwater use
Maintenance-free: No moving parts, pure physical measurement, no calibration required
High accuracy: Flow velocity accuracy up to 1 mm/s, water level accuracy within 1 mm (within 2m range)
Chemical resistant: Not affected by reagent interference or fluid viscosity

Application Scenarios:
Ideal for rivers, open channels, reservoirs, and pipelines. Real-time monitoring of flow velocity, water level, temperature, instantaneous and cumulative flow.
