Leak Detection for Aboveground Storage Tanks

Mass Technology's method of leak detection is not only less costly and safer than conventional methods, it is also more precise. Our mass measurement system eliminates the guesswork involved with other technologies. The measured variable - the pressure imposed by the mass of the fluid contents of the tank - is a quantitative measurement. The fluid containment capability of the tank is determined, as well as an accurate measurement of the leak rate, if a leak exists. The system is capable of measuring leak rates of less than one gallon per hour in 60,000-barrel storage tanks. This is a detection capacity of less than one part per million based on tank capacity.

Safe, Accurate and Economical Leak Detection Services for AST’s

Mass Technology Corporation is a leading provider of precision testing for aboveground fluid storage tanks. Our mass measurement system - which is applicable to all types and sizes of tanks and viscous products - is safer, more economical, and more precise than conventional testing methods. It is field-proven and third-party certified. Employing improved pressure-sensing transducers, enhanced data collection, and experience gained from practical applications, Mass Technology’s system detects leaks at a threshold of less than 0.80 gallons per hour in a 100,000 barrel tank.

Our technique involves lowering a bubbler unit to the tank bottom. A differential reference tube is placed just above the liquid surface. Nitrogen gas is conveyed to the bubbler unit at a precisely controlled rate, and an additional tube is attached that eliminates the friction and subsequent back-pressure affects on the differential pressure transducer. The pressure required to generate a stream of bubbles at tank bottom corresponds to the differential pressure as a result of the fluid mass. The pressure is measured by a micro-sensitive differential pressure transducer, which is recorded on a real-time basis and post processed. Data analysis routines accurately calculate any changes in the mass of fluid within the tank and determine if there is a loss.
