ABSTRACT:
A conductivity monitoring system which includes at least three electrodes disposed within a housing of a conductivity cell, into and through which a fluid to be monitored is caused to flow. One of the electrodes is a common electrode and is positioned closer to one of the other two electrodes. The conductivity is measured between the wide spaced pair of electrodes and between the closer spaced pair of electrodes, with the difference being taken as the actual conductivity. With this arrangement, changes in the conductivity as a result of foreign matter collecting on the electrodes and the housing over a period of time are compensated for, since the difference in the conductivity between the two pairs of electrodes remain the same, even though the conductivity between each respective pair may change.
