Abstract:
1. A pipe leak detection system, comprising: a plurality of meter pairs, each respective pair having a fluid flow meter and a sound velocity meter at a plurality of locations along a common pipe, each pair successively monitoring respective changes in fluid flow and sound velocities of fluid in the pipe, and each pair comprising a meter controller; and a master controller, coupled to the meter controllers of the meter pairs, for associating changes in monitored fluid flow and sound velocities by two of the meter pairs at two locations along the common pipe with a leak event in the pipe occurring between those locations, wherein each meter controller gathers samples of both sound velocity and fluid flow velocity, records time of each sample and periodically transmits batches of samples to the master controller, wherein the master controller receives time-stamped fluid flow and sound velocities data from each meter controller of the meter pairs and associates changes in the time-stamped fluid flow and sound velocities data with a leak event.
