Method for detecting leaks
This patent describes a method for determining leaks in a storage tank containing a liquid. The method consists of: locating a float means initially at a depth in the liquid approximately equal to V/sub L//S/sub L/ where V/sub L/ is the volume of the liquid in the tank and S/sub L/ is free surface area of the liquid in the tank; saturating vapor above the liquid in the tank with vapor of the liquid by atomizing so as to fill the vapor above the liquid with small drops of liquid or coating surfaces of the tank above the liquid with a thin layer of the liquid so as to hasten saturation of the vapor above the liquid, so that temperature variation of the liquid in the tank does not change the depth at which the float means floats in the liquid; and determining changes of location of the float means in the tank.
