Harwil manufacturers Flow Switches, Liquid Level Switches, Chemical Feed Pump Controllers.  Our switches are used by most of the major Pool and Spa equipment manufacturers.    We also work in water treatment with our best-in-the-industry Chemical Feed Pump Controllers.  These Chemical Feed Pumps use a flow switch to detect when someone uses water in the home and turns on the water treatment device, such as a chlorine feeder.  When the water is turned off, the controller turns the Chemical Feed Pump off.  Our flow switches are used by the irrigation industry and our level switches are used to maintain fluid levels in tanks.  Our Q-5 flow switch usually outlasts the system where it is installed and is used by Navy in the ships.  Most of our switches can be used in potable water.
