Abstract:
1. A method of filling a target container with a predetermined target mass of a free-flowing substance from a reservoir using a dosage-dispensing device to fill the target container with measured doses of the substance, the dosage-dispensing device comprising a valve which allows the mass flow rate of the substance from the reservoir into the target container to be varied, a time-keeping device, a balance, and a controller unit to control the valve, the controller unit including an adjustment module in which a desired mass flow rate and a delay interval are stored; the method comprising the steps of: selecting the desired mass flow rate by performing the steps of: beginning a filling process by starting to measure elapsed time using the associated time-keeping device, starting to measure the mass of the substance present in the target container using the balance, and opening the valve, the balance transmitting a weighing signal to the controller unit; and adjusting the flow of the substance, at a predetermined elapsed time, by performing in the adjustment module, the substeps of:
