Patent ID: 8758628

Claim:
A sensor assembly for a water softening system comprising: a first treatment tank having a first valve assembly and a sensor probe; a first flow meter within said first treatment tank; a second treatment tank having a second valve assembly; a second flow meter within said second treatment tank, wherein said first flow meter and said second flow meter are different; a brine tank independently connected to each of said first treatment tank and said second treatment tank; and a controller configured for communicating with said sensor probe and said first flow meter within said first treatment tank, and said second flow meter within said second treatment tank, said controller configured for communicating with said first valve assembly and said second valve assembly, said first flow meter being configured to track a first number of gallons of fluid flowing through said first treatment tank until regeneration is necessary in said first treatment tank, and when regeneration is necessary in said first treatment tank, said controller records said first number of gallons and sends a signal to said first valve assembly to switch from a service phase to a regeneration phase, and triggers operation of said second treatment tank; and said second flow meter being configured to track a second number of gallons of fluid flowing through said second treatment tank and, when said second number of gallons of fluid reaches said first number of gallons, said controller sends a signal to said first valve assembly to switch from said regeneration phase to said service phase and to said second valve assembly to switch from a service phase to a regeneration phase.
