Abstract: A method is described and shown for operating a filling device with a filling valve for controlling a medium flow, with a discrete-time sampling flow sensor for measurement-based capture of the medium flow discharged by the filling valve and with a controller for actuating the filling valve, wherein the control unit controls the filling valve to perform a filling process with a defined target filling quantity, taking into account the measured actual filling quantity, which is determined with the aid of the flow measurement values captured by the flow sensor. A measurement error caused by the discrete-time sampling of the flow measurement is reduced by synchronizing the start of the filling process between the filling valve and the flow sensor so that the first sampled flow measurement value of the flow sensor has a defined time relationship to the initial opening of the filling valve during the filling process.
