ABSTRACT:
A Coriolis flowmeter having a rotor assembly positioned within a housing and having center axis of rotation. The rotor assembly has a plurality of flow channels, each of which extends from the outer periphery of said rotor assembly to a center recess of said rotor assembly. An inlet extends material through the flow channels to an outlet of the flowmeter. The rotor assembly rotates about the center axis of rotation as the material passes through the flow channels. Coriolis forces generated by the material flowing and the concurrent rotation of the rotor assembly cause a flexure element comprising a part of the rotor assembly to assume an arcuate offset. Strain gauges or sensing coils and magnets generate output signals indicative of the magnitude of the angular offset and the mass flow rate of the flowing material. A motor connected to the rotor assembly can rotate the rotor assembly at an increased velocity to operate the flowmeter as a pump that generates output signals indicative of the pump throughput.
