  • 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 ...

  • 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 ...

  • Refrigerant leak detection is heavily regulated by government agencies

    Refrigerant leak monitoring in refrigeration and air-conditioning (RAC) systems and heating, ventilation and air conditioning (HVAC-R) equipment is very challenging, even for the most skilled HVAC-R technician. The leak could be well concealed from view in tubing, a system component, or in an operating or safety control component. With the Environmental Protection Agency (EPA) laws documented ...

  • 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 ...

  • Detection and Location of Leaks in Geomembrane Liners Using an Electrical Method: Case Histories

    ABSTRACT A field-proven electrical technique, developed at Southwest Research Institute, San Antonio, Texas, is commercially available to detect and locate leaks in geomembrane liners. The electrical technique is used to inspect 100% of the geomembrane material that is covered by a conducting liquid. A voltage applied across the liner produces a uniform electrical potential distribution in ...

  • 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 ...
