Abstract: A system and method for correcting flowrate measurements of a flowmeter includes receiving at least one of flow distorting parameters, flowmeter physical and operational parameters, a current flowrate value measured by the flowmeter, and fluid physical properties; determining a flow regime based on the current flowrate value; selecting at least one flow equation based on the determined flow regime; computing an output signal based on the selected flow equation and at least one of electromagnetic equations and/or physics-based equations, the flow distorting parameters, the flowmeter physical and operational parameters, and the fluid physical properties; determining a corrected calibration factor using the computed output signal and the current flowrate value; and transmitting the corrected calibration factor for correcting flowrate measurement of the flowmeter.
