Abstract:
1. A method of filling a container with a filling material having a first liquid component and a second liquid component in a predetermined ratio, said method comprising supplying said first liquid component from a first tank to said container by causing said first liquid component to flow in a first direction through a filling material line, said filling material line being closable by a first filling valve unit, there being a flow rate measuring unit provided to determine an amount of first liquid component fed through said filling material line, feeding said second liquid component into said filling material line, said filling material line having been filled at least in part by said first liquid component, thereby displacing at least a portion of said first liquid component from said filling material line by causing said at least a portion of said first liquid component to flow in a second direction opposite to said first direction, detecting an amount of said second liquid component fed into said filling material line by using said flow rate measuring unit to detect motion of said first liquid component in said second direction in said filling material line, said motion being caused by feeding said second liquid component.
