Abstract (en)
[origin: WO8101054A1] A method of high sensitivity for measuring leakage of liquid from a storage tank (11) which comprises introducing a sensor (12) into the liquid in the tank (11), the sensor (12) being coupled to means (17) for sensing displacement of mass, measuring the displacement over a known period of time and calculating the leakage rate. The sensor (12) is designed to compensate for evaporative losses and temperature changes.
