In order to simultaneously fill several containers with a liquid, gaseous or solid flowable medium, without it being necessary to measure and monitor the filling volume or weight of each container, the filling apparatus has a pipe system (10) for carrying the medium to be filled. The pipe system includes a plurality of branch lines (13, 113, 213) leading to valves (20, 120, 220). In the branch lines there are arranged volume chambers (40, 140, 240) having impellers jointly placed on a shaft (41) with a system pressure-dependent braking device (45). The impellers are rotated by the medium flowing through the volume chambers. A balance (50) or a rotary piston meter (150) is associated with only one valve (20) of all the valves controlled by a control cylinder (25) and is used for controlling the latter.
