Abstract:

Measuring, controlling, and automating inventory of product stored in a collapsible tank. An interface device can interact with a sensor installed at the collapsible tank and a metering device, such as a flow meter, to generate a strap table for the collapsible tank. The strap table can include entries that correlate a process value measured by the sensor to a volume of product corresponding to that process value. Current volume of product stored in the collapsible tank can be determined by comparing a current process value to entries in the strap table or by an interpolation process. The interface device can generate an updated strap table based on a relaxation curve to account for settling of the collapsible tank. The interface device can synchronize data with a host device, such as a personal computer or handheld computer, that includes software for tracking inventory in collapsible tanks.
