ABSTRACT:
A method of checking the volume of containers is disclosed according to which a gas is fed into a volume which is correlated to the volume of the respective container and a signal which depends from the fed amount of gas is evaluated as signal indicative of the volume of the container. In order to substantially reduce the time of the measuring cycle at such a method a gas is fed to the volume which is correlated to the volume of the container at a controlled flow, i.e. the mass flow of the gas per unit of time is pre-set in a controlled manner such that it is possible to drastically reduce the time spans during which it is necessary to wait due to transient processes and a chamber which must be loaded in advance will become superfluous.
