Abstract: A bypass flowmeter for measuring the material flow in a conduit. An optimum pressure drop is developed across the flowmeter by coupling the material outlet of the flowmeter to the throat of a venturi positioned within the conduit. This increased pressure drop improves the material flow rate through the flowmeter. This enhances flowmeter accuracy and sensitivity and the flowmeter's ability to measure mass flow rates for low density materials such as gas. The ratio of the material flow within the flowmeter to that of the conduit is derived with improved precision over prior arrangements which assume a constant ratio of material flow between the flowmeter and the conduit. The material flow information for the conduit is obtained for materials having a varying viscosity by the use of a differential pressure sensor which measures the pressure drop across the flowmeter and transmits this information to instrumentation which uses it to derive material flow information for the conduit with improved precision.

Abstract: A flowmeter positioned inside a case having compliant membranes for case ends. The membranes have an axial compliance sufficient to allow the flow tube to expand/contract freely in response to thermal changes without a permanent deformation of the flow tube.

Abstract: A Coriolis flowmeter having an outer rotor positioned within a housing and having a recess coaxial with a center axis of rotation. A Coriolis rotor is positioned in the recess of the outer rotor and has a center of rotation coaxial with the center axis of rotation. The Coriolis rotor has a plurality of holes, each of which extends from the outer periphery of said Coriolis rotor to a center recess of said Coriolis rotor. The outer rotor has a plurality of holes, each of which extends from the outer periphery of the outer rotor to the recess of said outer rotor with at least some of said holes in said outer rotor being aligned with a corresponding one of said plurality of said holes in said Coriolis rotor. A fluid inlet extends fluid through holes of both the outer rotor and the Coriolis rotor to a fluid outlet of the flowmeter. Both rotors rotate about the center axis of rotation when fluid is received and passes through the holes of the rotors.

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.

Abstract: A pair of flowmeters having unequal flow carrying capabilities are effectively connected in parallel to receive a material flow. The material flow through the flowmeters supplies output signals to associated meter electronics which derives mass flow and other information for each meter. The meter electronics is pre-programmed with information regarding the physical characteristics of each flowmeter. The meter electronics uses the pre-programmed information and the derived material flow velocity for each meter and other information to determine the viscosity for the material in the flowmeters.
