Abstract
A system and method for monitoring liquid tanks that includes a submersible sensor within the tank below liquid surface. The system may also include a secondary sensor to determine ambient conditions, and a controller to determine when changes in liquid level are due to ambient events, or potential breach of system. A calibration rod may be used to monitor displacement of liquid in the tank and calibrate system to determine changes in height of liquid level.
