Patent ID: 7258007

Claim:
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 reference body ( 3 ), said reference body being held in suspension in said enclosure ( 1 ) in a totally immersed condition of said enclosure 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 of the enclosure, 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 ).
