Abstract:
1. A method for pressure-filling containers with a filling material using a single-chamber filling system having a filling element that, in a filling element housing, exhibits a liquid channel having a liquid valve, said liquid channel being connected, in a direction of flow of said filling material upstream of said liquid valve, to a liquid space of a filling material tank that is partly filled with said filling material and that is maintained at a pre-tensioning or filling pressure, and wherein, in a direction of flow of said filling material downstream of said liquid valve, said filling material tank forms a discharge opening against which a container is arranged with a container opening thereof in sealed position, at least during filling thereof, and wherein said filling material tank comprises a return gas tube that extends into said container during filling thereof and through which, during filling, inert gas displaced from said container, which is pre-tensioned with an inert gas, is returned into one of a manifold carrying said inert gas at said pre-tensioning or filling pressure, and a gas space of said filling material tank, and in which, after immersion of a lower return gas tube end of said return gas tube into a filling-material surface rising in said container, said filling material rises to a level at which further filling of said container with the filling material is ended, said method comprising effecting further filling of said container, wherein effecting further filling of said container comprises providing a probe disposed or configured in a return gas channel, said probe being configured to generate a probe signal as soon as said filling material, which rises in said return gas channel, reaches a response level of said probe, and responding to said probe signal by closing said liquid valve.
