ABSTRACT:
A water softening system is provided in which a determination is made whether the slow rinse cycle of a regeneration has been completed or is abnormal. A reference cell and a spaced sensing cell are provided in a water tank. The impedance difference of the solution between the reference cell and the sensor cell is sensed. If the impedance difference is a first state, then after a predetermined period of time a determination is made if the impedance difference is a second state. If the impedance difference is a second state, then after a predetermined period of time a determination is made if the impedance difference is a third state. If the impedance difference is a third state, this indicates that the sodium ion concentration is uniformly reduced in the zone between the reference cell and the sensing cell and that the slow rinse cycle has been completed.
