Abstract
A container is filled to a predetermined target mass of a free-flowing substance with the help of a device that dispenses measured doses of the substance. The device has a valve for variably adjusting the mass flow rate of the substance from a reservoir into the container. The device further includes a means for measuring the elapsed time from the beginning of the filling process, a balance for determining the mass of the substance in the container, and a controller unit for controlling the valve. The controller unit includes an adjustment module, and a memory unit wherein a desired mass flow rate is stored. At an elapsed time, if the mass flow rate is smaller or larger than the desired mass flow rate the flow rate is respectively increased or decreased by a flow rate adjustment.
