Product Introduction:
SCJ-LD07 paddy field water level meter is a device that uses microwave technology to achieve accurate non-contact measurement of water level. The device is small and light, easy to install, and can be used for non-contact measurement of liquid levels in farmland, ditches, sewage pipe networks, culverts, water tanks, etc. The paddy field water level meter has high measurement accuracy, low power consumption, small size, light weight, strong resistance to environmental interference, and good reliability and maintainability. It works all-weather and is suitable for outdoor or unmanned monitoring. It can automatically measure and calculate data, has high stability, long service life, and is maintenance-free.
Working principle:
It adopts the principle of microwave reflection, has strong anti-interference ability, can measure data up to millimeter level, and has a built-in integrated acquisition, transmission and power supply system. It is not affected by weather, air pressure, region and other factors, can operate in various complex sites, and can adapt to different environments at any time after changing scenes. It is mainly used for variable floating measurement of water level in rice field irrigation.
