Abstract
A method and an apparatus for filling at least one liquid into at least one cavity. The method comprises filling a predetermined filling volume of the at least one liquid into the at least one cavity and determining if the liquid in the at least one cavity reaches a first liquid level in the at least one cavity. Filling the predetermined filling volume of the at least one liquid and the determining if the first level has not been reached, is repeated until enough volume of the at least one liquid has been added to the cavity or if the first level has been reached. The predetermined filling volume is equal to or smaller than a buffer volume above the first liquid level in the at least one cavity.
