Leak Detection and Location of Water Pipes Using Vibration Sensors and Modified ML Prefilter

Leak Detection and Location of Water Pipes Using Vibration Sensors and Modified ML Prefilter

This paper proposes a new leak detection and location method based on vibration sensors and generalised cross-correlation techniques. Considering the estimation errors of the power spectral densities (PSDs) and the cross-spectral density (CSD), the proposed method employs a modified maximum-likeliho...
