Abstract

A method for measuring the volume (V) of a gas in a container (1) comprises obturation of the vent(s) (3) of the container and then introduction or withdrawal of a known gaseous mass flow (dm/dt) into and out of the container (1), respectively. The pressure change (dp/dt) caused by the mass flow and the sound velocity (u) in the container are determined, and the volume of the gas in the container is calculated by the formula: V = u<2> dm/dt 1/dp/dt, wherein V is the volume to be determined, u is the sound velocity, dm/dt is the mass flow, and dp/dt is the pressure change. An apparatus for carrying out the method has means (4) for obturation of the vents (3), means (5) for introducing or withdrawing a known gaseous mass flow (dm/dt), transducers (6, 7) for measuring the pressure and the sound velocity as well as calculating means (8). The means for introducing or withdrawing a known gaseous mass flow can include a mass flow can include a mass flow regulator.
