APPARATUS, METHODS AND COMPUTER PROGRAM PRODUCTS FOR GENERATING MASS FLOW CALIBRATION FACTORS USING A NORMAL MODAL DYNAMIC CHARACTERIZATION OF A MATERIAL-CONTAINED CONDUIT |
摘要 |
Abstract of Disclosure A calibration factor for a sensor including a material-containing conduit and a plurality of motion transducers operative to generate motion signals representing motion of the conduit is determined from a normal modal dynamic characterization of motion of the conduit. The calibration factor may be generated by generating a solution to a modal differential equation of motion in a modal domain including a plurality of normal modes of motion of the conduit, and by generating the calibration factor from this solution. The normal modal dynamic characterization may characterize motion of the conduit as a function of a modal Coriolis term that describes coupling among a plurality of normal modes of the conduit responsive to mass flow in the conduit. The modal Coriolis term may be determined from a mode shape function that describes modal motion of the conduit as a function of location on the conduit. The invention may be embodied as methods, apparatus and computer program products.
