Abstract
A flexible storage container may have a first footprint when empty, and retracts to a second footprint when filled with a substance. A load sensing apparatus used for determining the volume of the substance in the flexible storage container can include a first set of load-sensitive sensors arranged in at least a region of the first footprint external to the second footprint, and a second set of load-sensitive sensors arranged within the second footprint. The sensor data from the load-sensitive sensors can be used to create a pressure level profile, and the volume of the substance contained in the flexible storage container can be calculated from the pressure level profile.
