Abstract: A storage tank leak detection system for detecting and measuring very small leaks in large horizontal cylindrical storage tanks. Embodiments include two highly precise quartz crystal type pressure transducers held at a constant temperature. A bubbler to achieve access to the hydrostatic pressure at the tank bottom and just below the liquid surface. First transducer and bubbler are used to measure fluid mass while second transducer and bubbler are used to measure fluid density then used in combination with data correction and regression techniques to yield a storage tank leak detection system for use in horizontal cylindrically shaped tanks with an extremely low leak detection threshold.

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.

Abstract: An intrinsically safe, precise, and cost effective storage tank leak detection system. Embodiments include a highly precise quartz crystal type pressure transducer, secured in a vacuum and held at a constant temperature. Said transducer is used in combination with data correction and regression techniques to yield a storage tank leak detection system with an extremely low leak detection threshold. The storage tank leak detection system is thought to be most useful for detecting very small leaks in very large storage tanks.
