ABSTRACT:
A gravitometer prover for measuring the density of a fluid for proving the accuracy of a gravitometer including an inner chamber member formed having an inner chamber for receiving fluid therein and an outer shell mounted about the inner chamber member in sealable relation thereto forming a cavity between the outer surface of the inner chamber member and the inner surface of the outer shell and a vacuum source in communication with the cavity for selectively imposing a vacuum in the cavity. A siphon tube removes solid particles entrained in test fluid as the inner chamber is charged. An orifice aperture vents gas components from the inner chamber.
