Abstract
A supervisory system and method for monitoring multiple flow rate fluid distribution systems and for determining the presence of a failure therein are provided. The system monitors the flow of fluid through the distribution system with a single flow meter, determines the flow rate at which fluid is flowing, and accumulates at that rate a water flow control value. If the accumulated water flow value exceeds a predetermined threshold, further flow of fluid in the system will be disabled. To take account of the multiple flow rates capable through the distribution system, the accumulated water flow value will decremented at the immediately preceding increment rate.
