Tank inventory and leak detection system
First Claim
1. Tank inventory and leak detection apparatus for detecting the status of a liquid storage system and its contents, said apparatus comprising:
- external detection means for detecting one or more conditions of liquid external of said storage system and for providing an external liquid signal;
internal detection means for detecting one or more conditions of liquid internal of said storage system and for producing an internal liquid signal;
means for storing decision criteria relating one or more of said external liquid conditions and one or more of said internal liquid conditions; and
indicating means communicating with said means for storing and responsive to said external liquid signal and said internal liquid signal for providing an indication of the status of said liquid storage system and its contents.

Abstract
A controller including a digital processor is connected to flow meters and overfill gauges suitable for placement in the fill ports of underground storage tanks at, for example, a gasoline service station. The station dispenser pumps are also connected to the controller. In addition, probes, including tank liquid level probes, line pressure probes, and leak probes capable of detecting small quantities of liquid leaking from the system, are also connected to the controller. Processor software programs use stored decision criteria relating liquid conditions external of the storage tank system and liquid conditions internal of the storage tank system and its contents to provide audio and visual indications of the status of the liquid storage system and its contents.
