A device for measuring properties dependent of volumetric flow and pressure, especially dynamic viscosity and/or density, of combustion gases, has a gas metering device and at least a gas flow resistance. The construction and the operation of such a measuring device are simplified in that a gas storage container (4), especially a capsule element, the volume of which varies according to pressure differentials ( DELTA p) between its inside (7) and the surrounding atmosphere, is linked to a connecting duct (5, 12) between a sealable gas inlet (2) and at least one flow resistance (15, 16). A chronometer (11) can be switched on and off according to predetermined volumes of the gas storage container (4). |
