A force measuring device comprises at least one gauge element which, at least, in some regions, is conceived as a spring element, the deformation of which changes the volume of liquid contained in a chamber delimited by the gauge element; the spring elements are equal to each other in every respect and so positioned that the spring characteristic is the same for all of them that the deformation remains in the linear domain of the spring characteristic and that the local change of volume of the chamber is proportional to the deformation of the respective spring element.
