Gas leak detection covers a wide range of leaks: pressure or vacuum and any gas. Sound dependent, Gas instruments detect turbulent flow produced as the fluid (liquid or gas) moves from the high-pressure side to the low-pressure side of a leak. Gas leak inspection is especially beneficial in areas where there is a saturation of gases or where a wide variety of gases, pressurized vessels and vacuum processes exist. For this reason Gas leak detection is used in many facilities for safety, environmental, energy or quality assurance programs.
A wide spectrum of sound is produce by Mechanical movements. One of the major contributors to excessive stress in machinery is friction. Gas instruments detect friction. By focusing on a narrow band of high frequencies, the Instruments detect precise changes in amplitude and sound quality produced by operating equipment. It then heterodynes these normally undetectable sounds down into the audible range where they are heard through headphones and observed on a display panel for trending, comparison, and analysis.
