Problems solved by technology
[0002] With the improvement of people's living standards, water tanks are used more and more widely, especially in the vast rural areas and enterprise factories in our country. How to effectively control the water level in the water tank, especially the convenience, reliability and safety, This puts forward very high requirements for water level control technology. In the past, the traditional water level control method used a mechanical water level controller to control the water level, but problems often occurred, and it was inconvenient and unreliable to use, which easily caused safety accidents. , and there is no corresponding protection function, a new water level control method needs to be studied
