Abstract
A storage tank leak detection system, including a quartz crystal type pressure transducer held at a constant temperature, a bubbler-based pressure sensor for reporting tank bottom pressure measurements to the transducer, a fluid surface measurement apparatus to report liquid surface pressure to the transducer, atmospheric pressure measuring apparatus, and a computing system for, based on data reported by all components, effecting data correction (corrected for atmospheric and container physical variations during data gathering) and regression techniques to yield data indicative of changes, if any, in mass content of a liquid storage container, such as a surface storage tank for petroleum and other chemicals.
