A device for operating a plurality of containers fillable with a medium may include a plurality of container valves each connected to of one of the containers, and a filling channel arrangement connectable or connected at one end to a media pressure source and connected at the other end to the respective container valves. In order to simplify determination of the media pressure in the individual containers and, furthermore, to permit different filling speeds, an emptying channel arrangement is connected at one end to the container valves and connectable at the other end to an unpressurized media hollow via an emptying channel valve. The media pressure in one of the containers can be calculated using a mathematical model. A filling channel valve may be provided for selectively connecting the filling channel arrangement to the media pressure source either directly or via a throttle in order to permit different filling speeds.
