摘要 The gas being tested is passed via at least one flow resistance. A gas reservoir vessel (4) undergoes vol. changes depending on the pressure difference between its interior (7) and the ambient atmosphere. After determination of the dependency the vessel is filled with the gas with accompanying vol. increase. The gas supply is interrupted and the gas allowed to escape via at least one flow resistance (15,16) as the vol. decreases. The time between specified vol. or pressure differences is measured (11). The volumetric flow and the gas characteristic under investigation are determined from the measured time and the volumetric or pressure difference change.
