摘要： An apparatus (150) and method (300) for determining a density compensated flow rate of a material flowing through a vibrating conduit. Signals are received from sensors (105, 105') affixed to the vibrating conduit (103A, 103B). An uncompensated flow rate and the density of said material is then calculated from the signals. The calculated density is then compared to a threshold density. If the calculated density surpasses the threshold density, the density compensation factor is determined by inserting said uncompensated flow-rate and said calculated density into a two dimensional N order polynomial equation relating density to flow rate error data wherein N is greater than 1. If the calculated density does not surpass the threshold density, the density compensation factor is determined by inserting said uncompensated flow rate and said calculated density into a linear equation relating density to flow rate error data. The density compensated flow rate is then dmpensated flow rate.

摘要： A system, method, and software are disclosed that determine a proportion of a majority component of a fluid that is flowing through a Coriolis flowmeter (404). Circuitry (402) receives pickoff signals (432) and a temperature signal (434) from the Coriolis flowmeter responsive to the fluid being flowed through the Coriolis flowmeter. The circuitry processes the pickoff signals and the temperature signal to determine a proportion of the majority component relative to the fluid. To determine the proportion of the majority component in one example, the circuitry determines a first volumetric flow rate based on a measured mass flow rate of the fluid and a reference density of the majority component. The circuitry then determines a second volumetric flow rate based on a measured volumetric flow rate, a temperature-varying density, and the reference density. The circuitry determines the proportion of the majority component based on the first volumetric flow rate and the second volumetric flow rate.

摘要： A Coriolis flowmeter is operated to generate accurate output material flow information over a wide temperature range that includes cryogenic temperatures. Heretofore, temperature compensation was provided using linear expressions that erroneously assumed the value of Young's Modulus E varied linearly with temperature. This resulted in unacceptable output information errors. The Coriolis flowmeter of the present invention uses non-linear compensation information stored in memory to generate accurate non-linear temperature compensated material flow output information at all temperatures including cryogenic temperatures. In one embodiment, the stored non-linear information represents measured values of Young's Modulus E that are used to generate accurate temperature compensated material flow output information. In another embodiment, the measured values of Young's Modulus E are curve fitted to derive non-linear expressions that are stored for use in generating the accurate non-linear temperature compensated output information.
