Abstract
The appts. has a main chamber to receive the body whose density is to be measured, and an auxiliary chamber. A subsonic wave generator subjects both chambers, in phase, to variations of pressure so as to generate subsonic waves. The appts. has a differential manometer arranged between the chambers, means for equalising the subsonic pressures of said two chambers, measurement appts. driven by the pressure equaliser, and for weighing the body within the main chamber.
