Abstract
A method for filling a container with a filling product in a filling-product filling system having a control valve, having the steps: a differential pressure Δpv decreasing across the control valve; and regulating and/or controlling the control valve as a function of the differential pressure Δpv which has been determined.
Claims12
A method for filling a container with a filling product in a filling-product filling system having at least two filling valves connected in parallel with one another, wherein the at least two filling valves are provided as control valves, comprising:
- determining a function of a volume flow q(t, Δpv) for the at least two filling valves as a function of a differential pressure Δpv across all filling valves connected in parallel;
- determining the differential pressure Δpv across all the filling valves connected in parallel;
- calculating the volume flow q(t, Δpv) through at least one filling valve of the at least two filling valves on the basis of the determined differential pressure Δpv;
- and
- regulating and/or controlling the at least one filling valve as a function of the calculated volume flow q(t, Δpv), wherein regulating and/or controlling the at least one filling valve comprises adjusting an opening position of the at least one filling valve based at least in part on the calculated volume flow q(t, Δpv), in the event of the determined differential pressure Δpv changing.

- and
- regulating and/or controlling the at least one filling valve as a function of the calculated volume flow q(t, Δpv), wherein regulating and/or controlling the at least one filling valve comprises:
- moving the at least one filling valve into an opening position, and
- adjusting the opening position of the at least one filling valve based at least in part on the calculated volume flow q(t, Δpv), in the event of the determined differential pressure Δpv changing.
