Abstract
A method of detecting a leak in a liquid storage tank utilizes a mass test in which a sample mass of liquid is removed from the storage tank and weighed. After a period of time, another sample mass of liquid, taken at exactly the same location as the first, is removed from the storage tank, and then weighed and compared to the first sample mass to determine whether there is a leak in the storage tank.
