ABSTRACT:
A liquid level monitoring system for underground storage tanks includes a submersible monitoring pipe system having telescoping sections that are biased to an extended position enabling the pipe to be self-retained within the tank between its upper and lower walls adjacent to and offset axially from a selected access opening in the tank, such as the discharge opening which normally accommodates the pump for the tank. The pipe system houses an electronic level sensor which is coupled to an above ground control system via conductor wires. An elongate accessing member having an openable and closable clamp jaw assembly for gripping the pipe system and disposing it in a compressed condition within the tank offset from the riser opening is provided as a part of the system.
