ABSTRACT:
A Coriolis mass flow meter apparatus, suitable for high temperature applications, wherein a preferred embodiment of the apparatus is comprised of two cantilever-mounted U-shaped flow tubes sinusoidally driven as the tines of a tuning fork by a drive mechanism mounted on standoff means attached to the flow conduits, with flow rates measured by velocity sensors mounted on suspension bars attached to the flow conduits. The flow conduits are encased in an inner thermal isolation partition wall structure containing apertures through which the suspension bars and standoff means protrude. A vented outer casing encloses the flow tube and partition wall structure, with insulation provided between the outer casing and the partition wall. Thermal control means are provided inside the space enclosed by the partition wall means. Gas cooling means are provided for the velocity sensors and drive mechanism. Flexible double wire structure means are provided to transmit the velocity sensor signals.
