US Patent 12000720 Product inventory monitoring

The present invention defines six unexpected benefits resulting from the automation of and improvements to inventory reconciliation and tank level monitoring at tank farms, terminals and refineries, commonly associated with refining and the transportation of, hydrocarbon fuels. In the implementation of an automated system for tank level monitoring and periodic inventory reconciliation, it has been discovered that both applications can be used to correctly identify maintenance needs and policy violations that were previously unable to be identified. The benefits include identification of thermal relief valve failure, transmix check valve failure, lock out/tag out failure, floating roof landing, and incorrect tank assignments.
