A storage tank leak detection system, including a quartz crystal type pre ssure transducer held at a constant temperature, a bubbler-based pressure se nsor for reporting tank bottom pressure measurements to the transducer, a fl uid surface measurement apparatus to report liquid surface pressure to the t ransducer, atmospheric pressure measuring apparatus, and a computing system for, based on data reported by all components, effecting data correction (co rrected for atmospheric and container physical variations during data gather ing) and regression techniques to yield data indicative of changes, if any, in mass content of a liquid storage container, such as a surface storage tan k for petroleum and other chemicals.
