Abstract

A method of detecting and locating a fluid leakage in a fluid pipeline network includes providing a plurality of sensors in an area of the pipeline network. Each sensor is configured to output data relating to an acoustic or vibration measurement associated with a part of the pipeline network proximate said sensor. The method further including recording the acoustic or vibration measurement output data, transforming the output data from a time domain to a frequency domain, determining a leakage condition, computing a sum value of the measured frequency values and associating said sum value with a corresponding sensor of the plurality of sensors, and locating a source of the fluid leakage by identifying one or more sensor(s) of the plurality of sensors in the area of the pipeline network that is closest to the source of the fluid leakage.
