Apparatus and Method for Calibration of Coriolis Meter for Dry Gas Density Measurement

摘要

A computer system is described. The computer system is provided with a processor and a computer readable medium. The computer readable medium stores computer executable instructions that, when executed, cause the processor to receive a first reference density measured at a first pressure and a second reference density measured at a second pressure. The first and second reference densities are measured at a reference temperature. The computer system receives a first tube period measured at the first pressure and a second tube period measured at the second pressure for a Coriolis meter, with the first and second tube periods measured at the reference temperature. The computer system receives at least two test densities and at least two test periods. The test densities and the test periods are measured at at least two test temperatures. The computer system associates an offset and a temperature correction factor with the Coriolis meter.

1. A computer system, comprising:
a processor; and a computer readable medium coupled to the processor, the computer readable medium being non-transitory and local to the processor, the computer readable medium storing computer executable instructions, that when executed by the processor causes the processor to:
receive a first reference density measured at a first pressure and a second reference density measured at a second pressure, the first reference density and the second reference density measured at a reference temperature;receive a first tube period measured at the first pressure for a Coriolis meter and a second tube period measured at the second pressure for the Coriolis meter, the first tube period and the second tube period measured at the reference temperature;receive at least two test densities and at least two test periods, the at least two test densities and the at least two test periods measured at at least two test temperatures; andassociate an offset and a temperature correction factor with the Coriolis meter using a unique identification code for the Coriolis meter.
