Leak Detection and Quantification of Leak Size along Water Pipe using Optical Fibre Sensors Package

摘要

Water pipeline condition monitoring is a challenging task that requires in-depth research and investigation. Leakages in pipelines can waste large quantities of water daily and affect the quality of the wa- ter supply. Detection, quantification, and accurate localisation of leaks can significantly improve the service delivered. In this context, a ‘contact-less’ optical fibre sensor package was developed with the ability to measure pressure and detect vibration in pipe. This study provides a description of the developed sensor and presents the findings from a set of experiments with the sensor package deployed inside a pressurised pipe. Results indicate that the proposed sensing strategy for leak detection and quantification is robust and promis- ing.
