ABSTRACT:
A densimeter for measuring the density of a fluid with a disk-shaped body having an axis with a horizontal component and being rotatably mounted on a shaft along the axis. Two open cavities are provided in the body so that the center of buoyancy of the body is displaced maximally from the axis. The body has a generally homogeneous density and includes a region wherein the density is different from that of the disk. Because of the density anomaly the center of gravity of the body is displaced from both the center of buoyancy and from the axis. The outer perimeter of the body and the cavities are circular so as to encounter minimal drag resistance while rotating in a fluid. When the densimeter is placed in a fluid, the disk will oscillate on the shaft. The density of the fluid is determined from the angular position of the disk on the shaft upon reaching equilibrium.
