  • Aboveground liquid storage tank leakage detection
    Patent number: 5686658
    Abstract: An aboveground storage tank is provided with a mass balance system for quantitative detection of leakage of liquid from a tank. Arrays of temperature sensors measure the exterior wall temperature of the tank and temperature sensors in an open-ended standpipe within the tank measure the temperature of stored liquid. The temperature measurements and measurements of liquid level change in a chamber mounted at the upper end of the standpipe are polled at intervals to detect changes of the mass of liquid within the tank.
