  • Leaks and spills - LNAP and DNAPL detection and clean up

    Any tank can leak. Most leaks can be cleaned up and responsible operators need equipment that does what’s needed. With an ATEX Zone 0 certified interface meter site operators can successfully achieve LNAP and DNAPL detection when monitoring petrochemical sites, tank farms, petrol station forecourts, landfills or remediation sites. If site technicians detect ...

  • Leak detection in semiconductor fab gas processes

    Problem Statement Often times in semiconductor fabs moisture levels are monitored to ensure that products aren’t damaged by excess moisture in the process. If there are above normal levels of moisture, pinpointing the source of that moisture can be difficult. The moisture could be evolving from impurities in gas tanks or leaks in the sampling lines. One way to avoid downtime ...

  • Detecting leaks through AMR data analysis

    Automatic meter reading (AMR) provides real-time consumption data, enabling to collect a huge amount of information about daily, even hourly, consumptions. It is then easy to assess lost volumes on the network, using supplied volumes information. However, because of the multiple components of water losses, the metering and calculation inaccuracies, the occurrence of new (detectable) leaks is ...

  • Sensor placement for leak detection and location in water distribution networks

    The performance of a leak detection and location algorithm depends on the set of measurements that are available in the network. This work presents an optimization strategy that maximizes the leak diagnosability performance of the network. The goal is to characterize and determine a sensor configuration that guarantees a maximum degree of diagnosability while the sensor configuration cost ...

  • Locating Leaks for Cooling Water Systems

    This article illustrates how to locate leaks on cooling water systems in loud, industrial environments like Nuclear or Coal power generating plants without digging or putting anything inside the pipeline.  Infrared-Energy Pattern Analysis (IR-EPA) works on all pipeline sizes and all pipeline materials because it identifies the water outside the pipeline instead of listening for leak noises ...

  • What Causes Water Main Leaks?

    The number one cause of water leaks today and moving into the future will be the aging infrastructure. “A large part of the US public water system dates back to the years shortly after World War II, therefore, a significant amount of buried infrastructure is at or very near the end of its useful life.” – Qureshi & Shah, Journal AWWA. When aging infrastructure is combined ...

  • 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 ...

  • GE Leakwise Application Notes: Leak Detection by Groundwater Monitoring

    Risks of Groundwater Contamination Hydrocarbon leakage, from Underground Storage Tanks (USTs) and from the bottoms of above ground tanks, can seep into the groundwater, where it forms a floating oil sheen, or a thick oil layer. This layer, if left undetected, ...

  • Early Ethylene Glycol Leak Detection in Power Plant Steam Condensate Is Essential

    Fossil fuel and nuclear power plants use heat exchangers to condense process steam back into liquid form. A heat exchanger works by transferring heat from one medium (steam) to another medium (air, water, or ethylene glycol). Many newer, closed cooling water system, power plants use ethylene glycol use ethylene glycol (C2 H6 O2 ) as a heat transfer fluid because of its high-heat transfer ...

  • Mancomunidad de la Comarca de Pamplona (MCP) Identifies 4 Leaks Using Inline Leak Detection

    Around the world, leaking water pipelines represent a major resource and financial loss for utilities. It is estimated that in some places, Non-Revenue Water exceeds 50 percent. In terms of financial losses, the World Bank estimates that NRW costs utilities worldwide about US$14 billion annually. By reducing these losses by half in areas with the highest NRW, it is estimated that US$2.9 billion ...

  • 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 ...
