ABSTRACT:
A cylindrical, open top, collapsible container is loosely fitted inside the tank. The bottom of this container floats on the liquid and its lateral surface folds or unfolds upon the rise or fall in the liquid level. The annular gap between the container and the tank's shell is connected to a bladder. The bladder is expanded or contracted in the required amounts by mechanical linkages between the floating bottom and said bladder.
