Download or read book Analysis and Design of an In-pipe System for Water Leak Detection written by Dimitris M. Chatzigeorgiou. This book was released on 2010. Available in PDF, EPUB and Kindle. Book excerpt: Leaks are a major factor for unaccounted water losses in almost every water distribution network. Pipeline leak may result, for example, from bad workmanship or from any destructive cause, due to sudden changes of pressure, corrosion, cracks, defects in pipes or lack of maintenance. The problem of leak becomes even more serious when it is concerned with the vital supply of fresh water to the community. In addition to waste of resources, contaminants may infiltrate into the water supply. The possibility of environmental health disasters due to delay in detection of water pipeline leaks have spurred research into the development of methods for pipeline leak and contamination detection. This thesis is on the analysis and design of a floating mobile sensor for leak detection in water distribution pipes. This work covers the study of two modules, namely a "floating body" along with its "sensing module". The Mobility Module or the floating body was carefully studied and designed using advanced CFD techniques to make the body as non-invasive to the flow as possible and to avoid signal corruption. In addition, experiments were carried out to investigate the effectiveness of using in-pipe measurements for leak detection in plastic pipes. Specifically, acoustic signals due to simulated leaks were measured and studied for designing a detection system to be deployed inside water networks of 100mm pipe size.

Book excerpt: Ageing infrastructure and declining water resources are major concerns with a growing global population. Controlling water loss has therefore become a priority for water utilities around the world. In order to improve efficiencies, water utilities need to apply good practices in leak detection. Leak Detection: Technology and Implementation assists water utilities with the development and implementation of leak detection programs. Leak detection and repair is one of the components of controlling water loss. In addition, techniques are discussed within this book and relevant case studies are presented. This book provides useful and practical information on leakage issues.

Book Synopsis Flexible In-pipe Leak Detection Sensor Module Design and Fabrication by : David Donghyun Kim

Download or read book Flexible In-pipe Leak Detection Sensor Module Design and Fabrication written by David Donghyun Kim. This book was released on 2015. Available in PDF, EPUB and Kindle. Book excerpt: Recent pipe bursts and explosions have caused not only financial losses but also a threat to public safety. Due to the recent incidents, governments have imposed strict laws with an increase in inspection regulation requirements. Large size networks make manual inspection of an entire complex system almost impossible. The need for autonomous automatic inspection systems is evident. A robust autonomous in-pipe leak detection robot was developed and reported in [1-5]. The developed system is able to accurately detect leaks in both pressurized gas and water pipes. This however was limited to 101.6mm (4in) internal diameter pipes. In practice, fouling of water pipes makes the internal pipe surface irregular. This thesis presents an analysis, design and experimental evaluation of a flexible detection system for pipes with large inner pipe diameter variation (80mm to 120mm). The system performance is evaluated through simulations and experiments. Experimental results show that the flexible sensor can detect leaks in pipes with simulated limescale. In addition, experiments were conducted to evaluate the effects of detector shift from the pipe centerline along with the effective area coverage of the leak by the sensor. The results show robust performance under large variations.

Book Synopsis Modeling and Monitoring of Pipelines and Networks by : Cristina Verde

Download or read book Modeling and Monitoring of Pipelines and Networks written by Cristina Verde. This book was released on 2017-05-21. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the analysis and design of advanced techniques for on-line automatic computational monitoring of pipelines and pipe networks. It discusses how to improve the systems’ security considering mathematical models of the flow, historical flow rate and pressure data, with the main goal of reducing the number of sensors installed along a pipeline. The techniques presented in the book have been implemented in digital systems to enhance the abilities of the pipeline network’s operators in recognizing anomalies. A real leak scenario in a Mexican water pipeline is used to illustrate the benefits of these techniques in locating the position of a leak. Intended for an interdisciplinary audience, the book addresses researchers and professionals in the areas of mechanical, civil and control engineering. It covers topics on fluid mechanics, instrumentation, automatic control, signal processing, computing, construction and diagnostic technologies.
