Help, I want to put a filter before and after my pump from the dirty ground water I will use. I think I need a device that will shut the pump off if the flow is weak(since this may indicate my filters are clogged). Anyone know what type flow switch I need and where I might get one? Part number would be great. What about how to wire it it?
If it were the filter on the outlet you were concerned with becoming clogged, you could protect the pump with a pressure control switch and a tiny water pressure tank, like those used on hot water heating systems.
