Method and filling system for filling containers in a volume and/or quantity controlled manner

摘要

A filling element includes a channel that forms a delivery opening for delivering filling into a container, a valve arranged in the channel for opening and closing the filling element, the valve being connected by a control valve device to sources for a main and additional component of the filling, and a filling-material section common to the components and forming a space. The element also includes flow meters for measuring volumetric flow of the filling and generating corresponding electrical measurement signals.

1. A method for quantity-controlled filling of a container with a filling material having a main component and an additional component, said method comprising during a filling process, controlling introduction of said main component and said additional component into said container through a common filling-material section and a filling element by using a flow-metering device associated with said filling element so as to end said filling process when said main component and said additional component have been introduced according to a required fill volume, wherein controlling introduction of said main component and said additional component comprises providing at least two magnetically inductive flow meters for use as a flow-metering device, said magnetically inductive flow meters being spaced apart from one another relative to a direction of flow of said filling material, at the beginning of a filling process, filling said filling-material section and a liquid space of said filling element with only said main component, said liquid space of said filling element being permanently connected to said filling-material section, during said filling process, in at least one preceding process section, introducing said additional component into a space formed by said filling-material section, said space being selected from the group consisting of a storage space and a proportioning space, using at least one of said flow meters through which only said main component flows, indirectly determining a volume of said additional component flowing into said space by measuring a volume of said main component displaced by said additional component from one of said filling-material section and said space, ending introduction of said additional component into said space when a volume of first component displaced by said second component from one of said filling-material section and said space, as measured with at least one flow meter, has reached a particular value, in a subsequent process step, introducing said main component into said filling-material section, through said filling element, and into said container, while concurrently entraining said additional component from said space, and measuring a volume of said main component flowing to said container using at least one flow meter through which only said main component flows.
