摘要
A vibratory flow meter (100) for correcting for an entrained phase in a two-phase flow of a flow material is provided. The vibratory flow meter (100) includes a flow meter assembly (10) including a driver (104) and with the vibratory flow meter (100) being configured to generate a vibrational response for the flow material. The vibratory flow meter (100) further includes and meter electronics (20) coupled to the flow meter assembly (10) and receiving the vibrational response. The meter electronics (20) is configured to generate a measured two-phase density of the two-phase flow using the vibrational response, determine the computed drive power needed by a driver (104) of the flow meter assembly (10), and calculate a density compensation factor using a liquid density of a liquid component of the two-phase flow, an entrained phase density of an entrained phase component, the measured two-phase density, and the computed drive power.
