Deep well pump water is not enough. What can be used to control the water level?

Electron probe. Deep well pumping water is not enough to pump groundwater or mineral water at the bottom of the well. In order to ensure the normal operation of the deep well pump, the traditional technology uses the electronic probe control principle to measure the liquid level in the well to control the water level. The biggest feature of deep well pump is that it integrates motor and water pump, and it is a kind of pump immersed in underground well for pumping and delivering water.
