Abstract
A method and an apparatus for measuring the amount of liquid in a container, and for causing the liquid to flow from the container to a point of use. The weight of the container is measured at several time intervals to determine the weight change of the liquid contained within. When the weight change is less than a predetermined fraction of either the weight of container weight and/or of the liquid originally contained in the container, a signal is generated to indicate that the container may be empty.
