The collar supports for the bottles to be filled enable a variety of bottles to be filled by single design of machine. The apparatus for filling containers by weight uses containers each (50) having a neck (51) supported within a collar (52) extending around the neck. The collar is mounted on the end of one of several radial arms extending from a circular plate (40), so that containers (50) may be moved beneath filling nozzles (60). The radial arm includes two hollow parts (2,3) connected together and incorporating a bar (5) of elastically deformable material. The bar includes a strain gauge which is connected to the control of the filling mechanism by an electrical conductor (10). The material of the bar (5) includes an elongate cavity (9) in order to ensure that the provision of a constant moment weight sensor. A screw (27) is provided to adjust the maximum permitted movement of the elastic bar.
