Abstract
A filling system pressure-fills containers with a filling material using filling elements for filling containers against a counter-pressure using a multi-phase treatment process that includes pre-pressurizing a container to a first pressure, filling them, and relieving the containers to ambient pressure. The system has a single pressure-measuring device, and a control device. The pressure-measuring device detects an internal-pressure profile for all filling elements during the treatment phases, and provides timing control of treatment duration of the phases. The control device either monitors or corrects treatment durations of all treatment phases of all the filling elements based at least in part on an internal-pressure profile detected by the pressure-measuring device.
