  • Leak detection by inverse transient analysis in an experimental PVC pipe system

    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 solvers can be used in the system operational diagnosis, namely for leak detection purposes, due to their capability to describe the dynamic behaviour of the systems and to ...

  • Calculating the cost savings for refrigerant gas leak detection

    The real benefits of refrigerant gas leak detection Following on from the last article, we feel that it’s natural to then discuss some of the practical reasons (cost savings) that will encourage the industry to take action and reduce their F-Gas emissions. Who requires refrigerant leak detection under the F-Gas proposals? There are a ...

  • Technical and safety practices

    Safety is absolutely paramount in the medical industry, with lives literally at stake if something were o go wrong. Regrettably, this was more than reinforced recently following the tragic news of a death of a newborn at a hospital in Sydney, Australia, after it was mistakenly administered nitrous oxide (N2O) instead of oxygen (O2) in July this ...

  • An electromagnetic-based method for pinpointing leaks in buried pipes: a practical validation

    In this paper, a time domain reflectometry (TDR)-based solution for detecting water leaks in underground pipes is described and experimentally validated. The proposed method strongly reduces the inspection time that is typically required by traditional leak detection methods. In fact, it can successfully inspect pipes that are hundreds of meters long. In this work, two different configurations ...

  • GE Leakwise Application Notes: Leak Detection for a Floating Roof Oil Storage Tank

    Oil Storage Tank with a Floating Roof Floating Roof Drainage Operation Stormwater accumulated on a concave floating roof of an oil storage tank may affect its floatation, making it necessary to immediately drain the water. This is usually done through a flexible pipe, running from the floating roof down the tank, with an outlet above the ground near the bottom of the tank. ...

  • Making Every Drop Count: Unitywater uses leak detection as a foundation for condition assessment

    It stands to reason why many utilities respond to leaks only after they receive a call about water gushing from a street or a complaint from a customer about a damp basement, or other signs of visible leakage. Human nature reflects the adage that is often easier to respond to an ...

  • Proper Monitoring Essential to Reducing ‘Fugitive Emissions` Under Leak Detection and Repair Programs

    The Clean Air Act requires refineries to develop and implement a Leak Detection and Repair (LDAR) program to control fugitive emissions. Fugitive emissions occur from valves, pumps, compressors, pressure relief valves, flanges, connectors and other piping components. Comparison monitoring conducted by the U.S. Environmental Protection Agency's (EPA) National Enforcement Investigation Center ...

  • Case study - Germany/Albstadt: How telemetry cuts the cost of leak detection significantly

    Introduction Albstadt is a town located in southwest Germany, about 80km south of Stuttgart. Albstadtwerke are the utility network distribution provider in this region supplying potable water, natural gas and electricity.  In addition to managing and maintaining the local distribution assets in Albstadt, Albstadtwerke operate and maintain two more potable water distribution ...

  • Detect Hydrogen Gas and Flames

    Under day-to-day conditions, people cannot see, smell, or taste the presence of hydrogen gas. Hydrogen, however, is very flammable and requires only a small amount of energy to ignite. In fact, if leaking from a pipe at a high enough pressure, hydrogen gas can self ignite without the aid of an external energy source. Working together, ...

  • Tackling Non-Revenue Water by Identifying Small Leaks

    Small leaks sink big ships – the same can be said for large-diameter pipes in utility networks. While large leaks or ruptures are seen as newsworthy stories accompanied by images of water flowing down the streets; smaller leaks can often be more devastating. Left undetected, they can add up over time, contributing significantly to ...

  • Hole Dug, Leak Found - City Of Ottawa Entrusts Smartball Platform To Look For Leaks In Tranmsission Main

    When your inspection task is to survey a critical pipeline for leaks, nothing is more satisfying than trusting your technology to predict the leak location and then standing by as the client excavates the area to find a flow of water within one meter of exactly where you said it would be. The above-described "leak-where-predicted" recently happened with the City of ...
