Abstract
A water flow monitoring system for determining the presence of leaks in plumbing pipes having water flowing through the pipes under high pressure includes a flow monitor which is mounted to the pipe for sensing the flow of water through the pipe. A controller composed of a timer and/or accumulated volume meter associated with the flow monitor, to determine when the flow has continued for a preselected period of time, and/or when the amount of water has exceeded a preselected accumulated volume threshold, and logic components responsive to changes in flow rate. Upon detection of flow for the preselected period of time, and/or preselected accumulated volume threshold, a valve is actuated to stop flow through the pipe.
