Abstract
In a method for filling a liquid volume into receptacles wherein liquid is admitted into a volumetric metering chamber by opening an inlet valve, the inlet valve is closed when an upper switching level is reached, the liquid is discharged from the metering chamber into a receptacle by opening the outlet valve, and the outlet valve is closed when a lower switching level is reached, the upper filling level actually obtained after closing of the inlet valve is measured, as well as the lower filling level actually obtained after closing of the outlet valve. With the values obtained thereby, the upper and lower switching levels are corrected, whereby the desired liquid volume can exactly be observed independently of pressure and flow conditions.
