Working principle:
SCJ-LD40 radar water level meter adopts 24G microstrip planar array antenna and frequency modulated continuous wave (FMCW) technology. The product has high measurement accuracy, low power consumption, small size, light weight, strong anti-environmental interference ability, and good reliability and maintainability. It works all-weather and is suitable for unmanned monitoring in the wild or mountainous areas. It can automatically measure and calculate data, has high stability, long service life, and is maintenance-free. It adopts the principle of microwave reflection and has strong anti-interference ability. The measurement data can reach the millimeter level and is not affected by weather, air pressure, region, and other factors. It can operate in various complex sites and can adapt to different environments at any time after changing the scene.
