ABSTRACT:
A method and apparatus particularly for monitoring leakage of a fluid contained within a double-walled tank into its interstitial space is disclosed. The sensor includes an element which is subject to physical change upon exposure to the material contained in the tank. The condition of the element is remotely monitored to determine leakage. In the case of an underground tank or oceangoing vessel, a second similar sensor sensitive to water may be employed to differentiate leakage into the interstitial space of the material in the tank from ground or sea water.
