Abstract

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 water 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 promising.
