Leak Detection and Localization through Demand Components Calibration

Leak Detection and Localization through Demand Components Calibration

The success in the application of any model-based methodology (e.g. design, control, supervision) highly depends on the availability of a well calibrated model. The calibration in water distribution networks needs to be performed online due to the continuous evolution of demands. During the calibration process, background leakages or bursts can be unintentionally incorporated to the demand mode...

Leak detection and localization using models: field results

This paper presents the practical results obtained on the field from two different methods for identifying and locating leaks in water distribution systems using network modeling based algorithms. Both methods are based on the sensitivity analysis of pressure measurements to the demand variation in any node in the distribution system. This work is mainly focused on the obtained results using bo...

Leak detection and localization using acoustic emission technique

Article history: Received 6 April, 2015 Accepted 10 October 2015 Available online 11 October 2015 This article provides a method of acoustic emission (AE) technique to detect leakage in pipeline and locate the position of the leakage. The AE sensor is made of piezoelectric effect transducer to pick up the acoustic emission signal which is generated from the turbulent flow at the leak position. ...

Leak detection

This paper will give an introduction to the leak detection of vacuum systems. Various methods to detect leaks as well as the most widely used helium leak detectors and their different applications are presented. Practical examples in the context of accelerator vacuum systems will illustrate the topic.
