The Det Tronics FlexSonic acoustic detector is the first non contact gas leak detector of its kind. Using a sophisticated algorithm, it listens for 24 unique acoustical "fingerprints" that are characteristic of pressurized gas leaks. By tuning out nuisance ultrasonic sources, this detector reduces false alarms, so your operations run

2016/11/17Vapor lock happens when the temperature of fuel gets high enough to transform liquid into a vapor state. Fuel pumps are designed to pump liquid, not air, and the increased pressure inside the fuel lines keeps the fuel pump from being able to keep the fuel moving. The result is fuel starvation causing the engine to run rough or completely stall.

Greenhouse GasUse in Electric Power SystemsCommon Emission SourcesSulfur hexafluoride (SF6) is a synthetic fluorinated compound with an extremely stable molecular structure. Because of its unique dielectric properties, electric utilities rely heavily on SF6 in electric power systems for voltage electrical insulation, current interruption, and arc quenching in the transmission and distribution of electricity. Yet, it is also the most potent greenhouse gas known to date. Over a 100 year period, SF6 is 22,800 times more effective at trapping infrared radiation than an equivalent amount of carbon dioxide (CO2). SF6 is also a very stable chemical, with an atmospheric lifetime of 3,200 years. As the gas is emitted, it accumulates in the atmosphere in an essentially un degraded state for many centuries. Thus, a relatively small amount of SF6can have a significant impact on global climate change. More information on long lived fluorinated greenhouse gases, their emissions, emission sources, and trends is available on EPA's overview of greenhouse gases page.See more on epa.govBenefit cost analysis of SF6 emissions mitigation in the iaee2021online.org/download/contribution/abstract/974/974...03/02/2021The potent greenhouse gas sulfur hexafluoride (SF6) is widely used in gas insulated switchgear (GIS) equipment in 126kV and 252kV GIS equipment to conduct a case study. The choice of the C4F7N/CO2 mixture stems from both an important market to consider when evaluating cost effective ways to reduce SF6 emissions.

2014/11/103. Is SF6 harmful for the environment? It has no ecotoxic potential, it does not deplete ozone. Due to its high global warming potential of 22.200 (*) it may contribute to the man made greenhouse effect, if it is released into the atmosphere. However in electrical switchgear the SF6 gas is always used in gas tight compartments, greatly minimising leakage.
