A device which is used to measure the density of a liquid, includes an enclosure ( 1 ) which is impervious to the liquid to be measured. The enclosure ( 1 ) has a rigid deformation-resistant casing housing at least one reference body ( 3 ) which is suspended in the enclosure ( 1 ). The enclosure ( 1 ) can move in relation to the reference body ( 3 ) such as, in the fully submerged state, to occupy a position which is a function of the density of the liquid in which the device is submerged. In the position, the enclosure exerts a pressure or tensile force on a measuring device ( 2 ) the movement of which is limited by the reference body ( 3 ).
