ABSTRACT:
A leak detector includes an air tight chamber having three openings therein. The first opening is connected to a source of compressed air or other gas. The second opening is provided to the fill pipe of a tank to be tested for leaks. The third opening is connected to a slope tube which is calibrated to detect changes in the height of a column of liquid in a slope tube. When pressure is applied to the chamber from the source of compressed air, bubbles are forced into the fill pipe. A corresponding pressure creates and maintains a column of liquid in the slope tube. Changes in the level of the fluid in the tank due to leakage result in a corresponding change in the level of fluid in the slope tube.
