摘要
A method and device indirectly monitors the purity of nitrogen gas manufactured from air using a permeable membrane to separate air components. A gas flow measuring device inserted in gas conduits downstream from the membrane monitors nitrogen gas purity by measuring normal flow and detects deviation from desired purity levels by changing gas flow caused by manufacturing apparatus malfunctions.
