Abstract
A self-contained monitoring system for monitoring the operating condition of a fluid treatment device. A housing provides a pair of flow passages, one for liquid supplied to, and the other for liquid treated by the fluid treatment device. Separate pairs of electrodes are provided, with one pair of electrodes extending into one of the flow passages and the other pair extending into the other flow passage. The conductivities between each pair of electrodes are provided as signals to an electronic circuit contained within the housing which provides electrical output signals indicative of the operating condition of the fluid treatment device based upon the conductivity of the supplied and treated fluid flows.
