The legendary Q-12 flow switch can be used in ¾ to 2 inch pipe and is capable of detecting even the lowest flow rates.

It can even include a temperature sensor to make sure everything is just right. Harwil flow switches are used in spas to keep the heater from running in unsafe conditions and protecting the users. The Harwil Q-8 flow switch is used to control UV and OZONE systems, turning them on when conditions are right. The CF-12 and CF-8 are used to control chemical feed pumps for residential and commercial pools. Harwil has been making the switches for over 30 years.
