Abstract

Water is a vital resource that is becoming increasingly scarce due to global warming, pollution and leaks in pipes, especially in urban areas. Finding non-intrusive methods to detect water flow variation and leakage is therefore essential to reduce losses in urban distribution networks that can have a significant economic impact. In this work, we have explored an acoustic method to detect the vibrations of water flows for metallic pipes. So, two piezoelectric sensors were used, the first one is made of a Lead Zirconate Titanate Ceramic (PZT) and the second one is a Polyvinylidene fluoride polymer (PVDF) to control and monitor the dynamic behavior of metallic water pipes at different flow rates.
