On the role of vibro-acoustics in leak detection for plastic water distribution pipes
Leaks have been detected and localized in water distribution in many countries for years, by using the cross-correlation of pipe vibration measured either side of a suspected leak and/or by using listening sticks. However, ...
Assessment of the Performance of Acoustic and Mass Balance Methods for Leak Detection in Pipelines for Transporting Liquids
(ASME-AMER SOC MECHANICAL ENG, 2010)
On-line leak detection is a main concern for the safe operation of pipelines. Acoustic and mass balance are the most important and extensively applied technologies in field problems. The objective of this work is to compare ...
The dynamic behaviour of a buried water pipe and its effect on leak location using acoustic methods
Leakage in buried pipes is one of the main concerns for water companies due to the scarcity of potable water sources. Older metallic pipelines have been replaced by plastic pipes in such systems, which makes it more difficult ...
The effects of resonances on time delay estimation for water leak detection in plastic pipes
In the use of acoustic correlation methods for water leak detection, sensors are placed at pipe access points either side of a suspected leak, and the peak in the cross-correlation function of the measured signals gives ...
Leak detection by inverse transient analysis in an experimental PVC pipe system
(IWA PUBLISHING, 2011)
Leakage reduction in water supply systems and distribution networks has been an increasingly important issue in the water industry since leaks and ruptures result in major physical and economic losses. Hydraulic transient ...
An algebraic observer for leak detection and isolation in plastic pipelines
(Institute of Electrical and Electronics Engineers, 2013-07-17)
Real time leak detection and isolation in pipelines: a comparison between Sliding Mode Observer and algebraic steady state method
(Institute of Electrical and Electronics Engineers, 2014-08-03)
An investigation into the effects of resonances on the time delay estimate for leak detection in buried plastic water distribution pipes
(European Assoc Structural Dynamics, 2014-01-01)
In water distribution systems, old metallic pipes have been replaced by plastic pipes due to their deterioration over time. Although acoustic methods are effective in finding leaks in metallic pipes, they have been found ...
