VIBRATORY FLOW METER, AND METHOD OF CORRECTING A DRAGGED PHASE IN A TWO PHASE OF A FLUID MATERIAL IN A VIBRATORY FLOW METER. A vibratory flow meter 100 is described for correcting a dragged phase in a two-phase flow of a fluid material. The vibratory flow meter (100) includes a flow meter assembly (10) including a trigger (104) and with the vibratory flow meter (100) being configured to generate a vibrational response to the fluid material. The vibratory flow meter (100) further includes meter electronics (20) coupled to the flow meter assembly (10) and receiving the vibrational response. Meter electronics (20) are configured to generate a two-phase density measured from two-phase flow using vibrational response to determine the computed drive power required by a flow meter assembly driver (104) , and to calculate a density compensation factor using a liquid density of a two-phase liquid flow component, a dragged phase density of a dragged phase component, the measured two-phase density, and the computed drive power .
