A salometer and flow rate sensor assembly for a water softener system including a brine tank containing a brine solution including at least one sensor housing provided in the brine tank, a first detector set associated with the housing and configured for indicating whether the brine solution is adequately concentrated and a second detector set associated with the housing and configured for measuring the brine solution flow rate during brine draw and refill cycles of regeneration.

Salometer and flow rate sensor assembly

A communication system for a water softener system that includes a controller configured for communicating with the water softener assembly and a remote display configured for sending and receiving at least one signal to and from the controller to a remote location.

Communication system for a water softener system

A grey water treatment system for use in conjunction with a water softener, including a grey water holding tank including a first inlet configured to receive grey water and a second inlet configured to receive spent brine from the water softener. The spent brine is mixed with the grey water in the holding tank to flocculate suspended solids in the grey water for subsequent removal.

Grey water treatment system

An apparatus and method for determining the end of a service step and the duration of a brine/slow rinse step in a water conditioner having a bed of ion-exchange material. A sensor probe and a reference probe are positioned in the bed of ion-exchange material vertically displaced from each other. Voltage from each of the probes are monitored over a plurality of time intervals. When the percent increase in the impedance ratio exceeds a pre-specified value the end of a service step is identified and a regeneration cycle is initiated. During the regeneration step, the rate of change in the impedance ratio of the sensor probe to the reference probe is calculated and used to detect two peaks in the rate of change of impedance ratio between the sensor probe and the reference probe, followed by terminating the brine/slow rinse step after both peaks have been detected.
