SYSTEM AND METHOD FOR ACOUSTIC LEAK DETECTION IN A UTILITY DISTRIBUTION SYSTEM

摘要

Method for identifying a leak indication in a utility distribution system including a pipe net- work for supplying a utility to a multitude of service connections and including a plurality of acoustic sensors mounted at the service connections. The method comprises the steps of: determining the presence of a normal fluid pressure in the pipe network; establishing a base- line noise indicator at a time of normal fluid pressure by using the acoustic sensors; deter- mining the presence of a difference fluid pressure in the pipe network; establishing a leak noise indicator at a time of the difference fluid pressure by using the acoustic sensors; and correlating one or more baseline noise indicators and leak noise indicators to determine ser- vice connections subject to leak indications.
