ABSTRACT:
A system and method for detecting leaks in a storage tank that includes a stored tank liquid and an immiscible test liquid, and there is an interface formed between the tank liquid and the test liquid. The system includes a transducer and electronic device. The transducer further includes a measuring cell and a standard cell. The level of the interface within the standard cell does not change when the level of the interface changes. The level of the interface within the measuring cell changes according to the level of test liquid in the storage tank. The signal generated by the cells are processed by the electronic device to indicate whether there is leakage in the storage tank.
