摘要： A method is disclosed that may include measuring a measured fluid density of a process fluid using a vibrational frequency of a fluid-conveying flow tube of the Coriolis meter where a density of a liquid phase of the process fluid is unknown. In addition, the method may include measuring at least one of an excitation energy metric of the Coriolis meter and a vibrational amplitude metric of the Coriolis meter. The method may include determining a Coriolis Mass Flowmeter Damping (CMFD) parameter using at least one of the excitation energy metric and the vibrational amplitude metric. Moreover, the method may include determining the density of the liquid phase of the process fluid using the measured fluid density and the CMFD parameter. Systems employing such methods are further disclosed.
