Abstract
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).

Device for measuring the density and/or specific gravity of a liquid of the type comprising an enclosure (1) impervious to the liquid to be measured,
- characterized in that the enclosure (1) is constituted by a rigid indeformable envelope enclosing at least one body (3), said reference body being held in suspension in said enclosure (1) in a totally immersed condition of this latter by means of at least one suspension member (4) projecting through said at least one opening (5) closed in a sealed manner, of said enclosure (1), this enclosure (1) being movable relative to the reference body (3) to occupy, in the totally immersed condition, a position relative to the body (3) as a function of the density of the liquid within which the device is immersed, this position being detected and/or measured by detection and/or measurement means (2) disposed within the enclosure (1).
