Abstract
There is disclosed a purging system for removing foreign matter from a fluid conducting conduit in which a sensor detects the presence of the foreign matter and produces an electrical signal which activates a timer which, in turn, connects a pump to the conduit for a given time duration to purge the conduit of the foreign matter. A counter also maybe connected to periodically activate the timer and purge the conduit, whether or not the sensor has detected foreign matter.
