Detect the water level of a water tank

Detect the water level of a water tank

Used for detecting the water level of a water tank for purposes such as water supply and water drainage in buildings

Apply voltage between electrodes with different length grounds, and pass a current when an electrode comes into contact with conductive fluid. (Used with a submergence detector.)
