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.
