Coriolis Flow Meter and method of operation of the flowmeter with a Flow Calibration factor independent of the density of the material flows

摘要

A Coriolis flowmeter sensitivity Enhanced flow in the flow of materials induces Coriolis deflections in a Flow Tube Coriolis ydeflexiones similar to offset in a BarIntegrated vibrationally coupled to the flow Tube.Both the Coriolis like deflections similar to Coriolis lasdeflexiones dephasing are determined by the material flow and are used to obtain information flujod coadyuvantementeThe material.The flowmeter achieves a constant Flow sensitivity in a range of changes in the density of the material: (1) varying the sensitivity acaudal in a First direction under the control of the twoIon between the vibration amplitude of excitation Mode of the flow Tube and the rod (2) by varying the offset and sensitivity to flow in an opposite direction under the control of the relationship.The amplitude of deflection of the tube Coriolis Flow and similar to the Coriolis deflection compensation bar.The relationship of Vibration amplitude of excitation Frequency varies with changes in the mode of excitation caused by changes of the density of the material.The ratio of amplitude of the Coriolis deflection and the Coriolis deflexionsimilar to change with changes in the magnitude of the separation of the frequency and the mode of excitation Frequency according toForm of Bending bar to compensation, which in turn is caused by changes in the density of the material.
