Abstract
The leak detector is utilized for determining the presence of a leak in an above ground tank of liquid having a lower specific gravity and a lower electrical or thermal conductivity than water. The leak detector includes a device for determining the level of water in the tank and a mechanism for sensing changes in the level of water in the tank over time. A leak detecting system utilizing the leak detector will also include an apparatus for determining the amount and rate of leakage relative to the capacity of the tank and the change of the level of the water in the tank over a selected time period.
