Patent ID: 8915269

Claim:
A method comprising using a filling system for controlled filling of a container with a filling material comprising a first component and a second component, said filling system comprising a first liquid channel for said first component and a separate second liquid channel for said second component, said first liquid channel having a first variable-volume chamber, and said second liquid channel having a second variable-volume chamber, wherein using said filling system comprises feeding said first component into said container, directly measuring an amount of said first component, generating a flow rate of the first component that results from the flow rate of said second component by introducing said second component from said second chamber into the container, thereby reducing the volume of said second chamber, and carrying out a controlled introduction of said second component, wherein carrying out said controlled introduction comprises using a flow meter to indirectly measure said flow rate of said first component that results from a flow rate of said second component, wherein the reduction of the volume of the second chamber brings about an increase in the volume of the first chamber and hence a flow rate of the first component into the first chamber and through the flow meter, wherein controlled filling consists of one of amount-controlled filling and volume-controlled filling, wherein controlled introduction consists of one of amount-controlled introduction and volume-controlled introduction, and wherein flow rate consists of one of amount flow rate and volumetric flow rate.
