FIELD: measurement equipment.SUBSTANCE: system of localised control of combustible gas leaks by primary parameters of measuring devices includes stationary sensors-gas analysers of combustible gases, an automatic control system, comprising a unit of sound and light alarm, a unit of control of sensors-gas analysers. The system additionally includes a unit of automatic switching of gas supply from the main process line into a reserve one and back, air-conducting boxes with a common swirler, where air is injected with required parameters from an air blowing plant, making it possible to move a gas leak in a certain direction to serially arranged sensors-gas analysers, which will make it possible with a sufficient extent of accuracy to determine local arrangement of the available leak in the shortest possible time from the moment of its formation.EFFECT: increased safety, timely, efficient and effective detection of a local leak point, reduced risk of gas concentration formation in the air.2 dwg |
