A filling quantity is accurately calculated and the filling quantity is accurately controlled with a simple configuration. The configuration includes a rotary body, a liquid distribution chamber, a plurality of filling flow path configuration units, each of which has a fluid path constituted by a liquid path connected to the liquid distribution chamber and a liquid valve and configured to individually introduce a liquid into a container, a filling control device, a liquid supply unit, a pressure difference information detection unit configured to detect pressure difference information between a liquid distribution chamber pressure, which is a pressure of the liquid in the liquid distribution chamber, and a filling atmospheric pressure detected as a pressure of a flow release unit in a filling flow path configuration unit at an arbitrary radial direction position of the rotary body, and a rotation information detection unit configured to detect rotation information of the rotary body, wherein the filling control device calculates a flow rate of the liquid flowing from a liquid outlet based on the detected pressure difference information, rotation information and a previously obtained relationship between the pressure difference information and rotation information and the flow rate of the liquid flowing from the liquid outlet of the liquid path, and controls a filling quantity of the liquid. |
