摘要：

A new method for determination of volume ratios and also the absolute value of volumes of vacuum vessels is presented. Method is based on a measurement of rate of pressure rise in a vacuum chamber at constant flow of inert gas. An example of measurement of a volume of a chamber with a nominal volume of 7 L is presented. For pressure measurements we have used a spinning rotor gauge (SRG) and He permeation leak was used as a gas source.
