Abstract
A method for gauging liquid in a container, the method comprising: a) assigning a local three axis coordinate system for the container; b) dividing the container into a plurality of regular volumes; c) disposing a first pressure sensor at a predetermined coordinate proximate the bottom surface of the container, with the pressure sensor producing an output related to detected fluid pressure at the predetermined coordinate; d) assigning to each of the volumes a corresponding volume location coordinate; e) numerically determining, for each of the regular volumes, a corresponding liquid mass value therein based on a relationship between the detected pressure at the predetermined coordinate and a calculated pressure at each of the volume location coordinates; and f) summing all of the numerically determined liquid mass values corresponding to the regular volumes to produce a total fluid mass for the container.
