Filling a container with a filling material having a first and second liquid components in a predetermined ratio includes supplying the first component from a tank to the container through a filling material line that defines opposite first and second directions, the line being closable by a valve. A flow-rate measuring unit determines an amount of first liquid component fed through the line in the second direction. The method also includes feeding the second component into the line, the line having been at least partially filled by the first component, and detecting an amount of the second component fed therein. Detecting the amount of the second component includes using a flow-rate measuring unit to detect motion of the first component caused by feeding the second component. The method then includes displacing at least a portion of the first component from the line along the first direction.
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.
An apparatus for filling a container with a filling material having a first and second liquid component in a predetermined ratio, said apparatus comprising a first tank for holding said first liquid component, a second tank for holding said second liquid component, a first filling valve unit for controlling flow of said first liquid component and said second liquid component into said container, a first filling material line connecting said first filling valve unit to said first tank, said first filling material line defining a first direction, which is toward the first filling valve unit, and a second direction, which is opposite said first direction, a flow rate measuring unit connected between said first liquid tank and said first filling valve unit to determine an amount of only said first liquid component conducted through said filling material line in said first direction, a second filling valve unit that, when opened, cause flow of said first liquid component in said second direction, and a second filling material line connecting said second filling valve unit to said second tank, thereby defining a path, when said second filling valve unit is open, between said second tank and said first filling valve unit, thereby enabling feeding of said second liquid component to said container, wherein said flow rate measuring unit indirectly measures flow of the second liquid by measuring flow of the first liquid in the second direction in response to flow of the second liquid toward the container.
