ABSTRACT:
An apparatus for measuring the density of a body which comprises: a main chamber adapted to receive the body whose density is to be measured; an auxiliary chamber; a subsonic wave generator for subjecting both of said chambers, in phase, to amplitude variations of pressure so as to generate subsonic waves; a differential manometer arranged between each of said chambers; means for equalizing the subsonic pressures of said two chambers; measurement means driven by said means for equalizing said subsonic pressures; and, weighing means for weighing said body, said weighing means being arranged within said main chamber.
