ABSTRACT:
A device for detecting leaks in containers that are open to the effects of rain and/or evaporation comprising an outer cylinder or container suspended in a container or vessel to be measured, such as, a swimming pool, an inner tube, an outer floating tube, an inner floating indicating rod and a float attached to the end of the floating indicating rod. The device is suspended in a swimming pool by a chain or rope attached to the outer cylinder. The inner tube is fastened to the bottom of the outer cylinder and a hole is formed in the bottom of the outer cylinder and an optional, long capillary tube is inserted in the hole. The inside of the outer cylinder is filled to a particular level and the relationship of the floating indicator rod and the environmentsl indicator tube is recorded. Periodically, the level is checked to see if there is a change in the level due to a leak in the pool or container. The relationship of the floating indicator rod and the environmental indicator tube indicates a net leak in the pool or vessel being tested.
