ABSTRACT:
In using the method for testing for leaks, in an above ground tank of liquid having a lower specific gravity and a lower electrical or thermal conductivity than water, first an amount of water sufficient to cover the bottom of the tank is introduced into the tank after which the level of the water in the tank is determined and changes in the level of the water in the tank over time are sensed. Additionally, the amount and rate of leakage relative to the capacity of the tank and the change in the level of the water of the tank over a selected time period are determined from the given parameters and the change in water level.
