Method and filling system for pressure-filling containers

A method for pressure-filling a container with a liquid filling material using a filling system comprising at least one filling element group, said filling element group comprising a plurality of filling elements, wherein during a first treatment phase, said container is arranged in a sealed position at a filling element and pre-pressurized with an inert gas to one of a clamping pressure and a filling pressure, during a second treatment phase, said container is filled against said one of a pressure and a filling pressure, and during a third treatment phase following said second treatment phase, said container is relieved to ambient pressure, wherein at least one of treatment duration and treatment time of said treatment phases is determined by a timing control, and wherein, during all treatment phases, a pressure profile of an internal pressure of said container is detected, said method comprising with a pressure-measuring device, detecting a pressure profile of an internal pressure of said container only at a filling element of said filling element group, and based at least in part on said pressure profile, for all treatment phases of all filling elements of said filling element group, at least one of monitoring treatment duration, monitoring treatment time, correcting treatment duration, and correcting treatment time.

An apparatus comprising a filling system for pressure-filling containers with a liquid filling material in one filling process with at least one filling element group comprising a plurality of filling elements for filling said containers against one of a clamping pressure and a filling pressure, wherein said containers, in a first treatment phase, are pre-pressurized by an inert gas to said one of a clamping pressure and filling pressure, and in a second treatment phase, said containers are filled to said one of a clamping pressure and a filling pressure, and in a third phase after said second phase, said containers are relieved to ambient pressure, wherein a control device provides timing control of one of treatment duration of said treatment phases and treatment time of said treatment phases, and wherein a pressure profile of internal pressure of said container during said treatment phases of said filling process is detected, said apparatus comprising a single pressure-measuring device for detecting a pressure profile for all filling elements, and a control device for at least one of monitoring and correcting one of treatment duration and treatment times of all treatment phases of all filling elements of said filling element group based on a pressure profile detected by said pressure-measuring device.
