A filling valve system configured to discharge a predetermined volume of liquid product to individual packages (130) is provided. The system comprises at least one filling valve (110, 210); a controller (150) configured to open said at least one filling valve (110, 210) thus allowing liquid product to be discharged and configured to close said at least one filling valve (110, 210); and a flow meter (140, 240) configured to measure the amount of liquid product being discharged through said at least one filling valve (110, 210). The system (100, 200) further comprises a pressure sensor (125, 225) configured to determine a pressure upstream of said at least one filling valve (110, 210), wherein said controller (150) is further configured to calculate an estimated discharge volume during a closing sequence of said at least one filling valve (110, 210) based on the determined pressure, and to initiate said closing sequence based on said estimated discharge volume. |
