Abstract
A system and method for using an electrolytic cell to detect an abnormal water flow state through the cell. The system applies a voltage across the electrodes in the cell and preferably waits until current through the cell has stabilized. The system then disconnects the voltage from the cell and begins measuring the floating voltage across the cell over time. A range of normal voltage decay intervals is determined for a flow state where water is flowing through the cell in an expected flow range. An abnormally low flow state will be detected as an abnormally long voltage decay interval.

A method for detecting an abnormal flow state in a chlorine generator, comprising:
- (a) providing an electrolytic cell, including,
- (i) an anode,
- (ii) a cathode,
- (iii) a passage for carrying salt-containing water, with said passage running at least in part between said anode and said cathode;
- (b) applying a driving voltage across said anode and said cathode;
- (c) removing said driving voltage across said anode and said cathode;
- (d) measuring a floating voltage across said anode and said cathode over time;
- and
- (e) correlating a decay in said floating voltage over time against a flow state of said salt-containing water in order to detect an abnormal flow state of said salt-containing water.
