ABSTRACT:
A control system apparatus for a fluid distribution system includes a low-voltage circuit and a positive displacement disc in a throughput line such that as fluid displaces the positive displacement disc a magnet associated therewith is also rotated. The rotating magnet sets up a magnetic flux that is sensed by a switch in close proximity to the rotating magnet and when the switch closes a low-voltage current is allowed to pass to a time delay relay, which in turn monitors the duration and strength of the low-voltage current and can, under program control, further actuate another branch of the low-voltage circuit, which causes a normally open valve to be closed by a solenoid. As the solenoid is actuated, the water flowing in the throughput line is shut off.
