摘要： A filter monitor is disclosed capable of sensing the presence of water in the filter. The sensor utilizes changes in capacitance of a water absorbing media which functions as a dielectric disposed between a pair of electrodes. The sensor is in communication with a valve means to interrupt the transient fluid when a predetermined amount of water is present in the fluid.
