Abstract
A method of accurately measuring volume of gas flowing through a conduit as a result of differential pressure of the gas within the conduit is disclosed. The method comprises determining flow of the gas through the conduit, and terminating flow of the gas through the conduit when the differential pressure is a preselected value. The gas flow and the resulting determination of gas volume are preferably referenced to standard temperature and pressure. Also disclosed is an apparatus for effecting the method.
