Abstract
An automatic apparatus for regulating and controlling the level of a liquid (1) in a tank (2) includes a liquid level detector (8). A vessel (3) associated with the tank (2) has a predetermined volume and is equipped with an upper closure (6) and with an open bottom (5) in communication with the interior of the tank (2) at a height below the level of the liquid (1). The automatic apparatus increases/decreases a liquid-free portion of the volume inside the vessel (3) and consequently transfers part of the liquid to/from the tank (2) through the bottom (5) in response to changes in the liquid level inside the tank (2) as detected by the liquid level detector (8).
