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).
Claims12
An apparatus for regulating and controlling a level of a liquid in a tank equipped with a closure, said apparatus comprising liquid level detection means, the apparatus comprising:
- a vessel associated with the tank, having a predetermined volume and equipped with an upper closure and with an open bottom in communication with the interior of the tank at a height below the level of the liquid;
- means for increasing/decreasing a liquid-free portion of a volume inside the vessel and for transferring part of the liquid to/from the tank through the bottom in response to changes in the liquid level inside the tank as detected by the detection means.
A method of using an apparatus for regulating and controlling a level of a liquid in a tank equipped with a closure, said apparatus comprising liquid level detection means, a vessel associated with the tank, having a predetermined volume and equipped with an upper closure and with an open bottom in communication with the interior of the tank at a height below the level of the liquid;
- means for increasing/decreasing a liquid-free portion of a volume inside the vessel and for transferring part of the liquid to/from the tank through the bottom in response to changes in the liquid level inside the tank as detected by the detection means;
- wherein said means for increasing/decreasing a liquid-free portion of the volume inside the vessel comprise means for introducing/extracting an inert gas into/from said vessel;
- the method comprising:
- applying positive/negative pressure cycles in the vessel, to generate shock waves inside the tank that contains fermenting must and disintegrate a cap of marc.
