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 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 ...

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 ...

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 ...

Detect Leaks and Analyze Water Consumption with WaterSignal

Did you know it will cost an estimated $1 trillion over the next 25 years to upgrade the nation’s water system to run more efficiently? While part of the problem is fragile, hundred-year-old water mains, it also falls on property owners to ensure they are doing their part to save water — for both the environment and their wallets. But how? ...

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 ...

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 ...

Integrated sensing technologies for detection and location of leaks in water distribution networks

Water distribution networks (WDNs) are infrastructure systems that have high socioeconomic values, for which efficient operation and management are required to ensure minimal amounts of waste which can be represented in the form of leaks. Leak detection is considered as one of the challenges faced by municipalities operating WDNs because it either involves shutting down the system or requires ...

Gas Detection and Monitoring Systems

In greenhouse applications, the accurate measurement of a number of environmental parameters such as carbon dioxide concentration, temperature, light intensity, water, humidity, pH and nutrient levels using sophisticated sensors is used to create a controlled environment for optimising plant growth rates while minimising energy usage. Carbon dioxide concentration is also one of the best ...

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 ...
