ABSTRACT:
Apparatus for measuring gas volume delivered at rapidly varying flow rates, over wide ranges of frequency of variation in flow rates, having a chamber with an outlet, means for varying the chamber volume to cause a volume of gas to be delivered from the outlet, and means for measuring changes in the pressure in and volume of the chamber during the varying, so that the volume of gas delivered therefrom can be derived.
