IN-LINE WATER HARDNESS SENSOR AND WATER SOFTENER CONTROL SYSTEM

Abstract:

A water softener regeneration system for a water softener configured to soften and filter water, the regeneration system includes a water hardness measurement system configured to determine a hardness value of water flowing out of the water softener. A brine tank is in communication with the water softener and operable to regenerate the water softener with brine from the brine tank. A controller is operable to control the brine tank, wherein the controller actuates by one of opening and closing the brine tank based on the hardness value which is indicative of the effectiveness of the water softener.
