Abstract: 2134085 9320956 PCTABS00027 The present invention comprises a method for measuring the amount, i.e., mass, of a volatile liquid which comprises passing the mass (18) over a heat loss measuring device (6, 8), calculating the amount of heat loss accompanying the vaporization of the mass and correlating the heat loss to measurement of heat loss of known liquid aerosol mass made with the same device. The method is especially useful in assuring uniform metered doses among multiple aerosol containers (12).
