Flow switch for water pump water pump flow sensor Description KWFS is installed in a water pipe and is a detection element that contacts fluid. When there is no water in the pipe or water does not flow, the target flow sheet is in a natural state; When there is water flowing, the target flow sheet is impacted and stressed, and the greater the water volume, the greater the impact force. When the flow reaches a certain value, the water flow pushes the target flow sheet,
