Product Description

What's this product?

       The Radar Water Level Sensor is independently developed by our company, utilizing FMCW (Frequency-Modulated Continuous Wave) technology with a 60GHz millimeter-wave radar signal as the carrier wave. The product features high measurement accuracy, low power consumption, compact size, and lightweight design. Its measurement process remains unaffected by environmental factors such as temperature, air pressure, sediment, dust, river pollutants, surface floating debris, or atmospheric conditions, while also demonstrating strong wind resistance and anti-vibration capabilities. The optimized algorithm ensures enhanced precision and stability in measurement results.

Operation principle

      Using a transmitter to emit ultra-high frequency electromagnetic waves towards the water surface, When electromagnetic waves hit the water surface and reflect back, the device detects the time difference between the outgoing wave and the echo, thereby calculating the height of the water surface.The reflection effectiveness of the echo signal improves with higher conductivity or greater dielectric constant of the measured medium.

What pain points can my product resolve?

    Real time monitor the water level in the manhole,configure alarm parameters.

    Remote monitoring of reservoir water levels, avoid overflow and flood. 

    Remote monitoring of water tank leak warning.

Features

1. Strong anti-interference capability, suppressing narrow wellbore wall interference;

2. Low power consumption, high reliability and maintenance-free;

3. Non-contact measurement, unaffected by ambient temperature/humidity, corrosion-resistant to water media;

4. IP68 protection class, moisture-proof and waterproof;
