  • Development of a long duration, free swimming, inline acoustic leak detection inspection tool

    Abstract Acoustic leak detection inspection tools have become a common technique to identify minute pipeline leakage before the leak and the defect producing it can become a larger problem or even a rupture level event. While these inspection tools only identify small ...

  • High throughput leak detection

    How can you improve leak testing precision and throughput? Various methods have historically been used to check leaks in systems and components—from bubble tests to rotameters and pressure loss detection. While these traditional methods have their place, they each have serious drawbacks in accuracy, throughput, and automation. You may be faced with more demanding situations that ...

  • F-Gas Regulations - An Update

    How does the latest F-Gas Regulation affect refrigerant leak detection? January 2014 saw the revised EU Regulation of F-Gases following publication of a draft proposal by the European Commission at the end of 2012. The much anticipated regulation changes aim to strengthen the existing F-Gas Regulation and to ‘encourage’ the industry to move towards a HFC free market and use of ...

  • GPS Verification for Leak Detection and Repair (LDAR)

    Pen and paper, as well as barcode scanners with handheld computers, have been used in the past to record locations and times for each inspection, but that information can be easily falsified. Many companies face the critical problem of not being able to verify and prove that data was taken correctly and accurately by field technicians. Audits have revealed false numbers that were recorded in ...

  • 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 ...

  • Comparison of dye testing and electrical leak location testing of a solid waste liner system

    Abstract: Dye tracing and electrical leak location testing were independently conducted to detect and locate leaks in the primary geomembrane liner of two cells in a municipal landfill. Despite extensive quality control and quality assurance programs, water in the leak detection zone after construction indicated that the primary liner had a leak. Fluorescein dye tests were conducted by placing a ...

  • Refrigerant leak detection is regulated by the US Environmental Protection Agency (EPA)

    Refrigerant leak detection is a difficult task in some heating ventilation and air conditioning systems or refrigeration and air conditioning systems. Sometimes the most experienced technicians find difficulty discovering a leak, which may be hidden in a system component, in tubing or in an operating or safety control switch. Refrigerant leak detection is a hot topic, following the recently ...

  • 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 ...

  • Case study - Plains Midstream– Alberta, Canada

  • 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 ...
