The system to fill a container with a liquid to a given level, and empty the container, has a connector (4) in the container interior (15) which opens into a rising tube (5). The rising tube sets the height of the level (14) of the liquid (2) in the container (1). The connecting tube (6) at the connector has a second setting to link the interior of the container with the ambient environment through it and the rising tube.
