1. Instructions
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.

2. 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.

3. Electrical characteristics

1. 7-32V power supply with wide voltage range, enabling flexible power source selection;
2. Battery-powered with low operating/standby current, enabling easy installation and maintenance-free.

5. Installation Instructions

5.1 Installation precautions
The device is mounted using a horizontal arm installation method, where two clamps secure the bracket and instrument to the crossbar (crossbar diameter range: 40mm-85mm). ensure the instrument's upper surface remains perpendicular to the water surface during installation.
