A system for weighing containers includes: a weighing station and a conveying path extending from an upstream infeed section to a downstream outfeed section. The conveying path includes a gripping stretch for gripping the containers and a release stretch for releasing the containers, disposed between the infeed section and the outfeed section; and a conveying device for conveying the containers from the infeed section to the gripping stretch, and the weighed containers from the release stretch to the outfeed section. The conveying device includes first and second groups of housings for receiving the containers and moving them from the infeed section to the gripping stretch. A gripping and transferring device transfers the containers from the gripping stretch to the weighing station and from the weighing station to the release stretch. The first and second groups are movable independently of each other from the infeed section to the gripping stretch.
