Patent ID: 8448491

Claim:
A vibratory flow meter ( 100 ) for correcting for an entrained phase in a two-phase flow of a flow material, comprising 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 and further comprising meter electronics ( 20 ) coupled to the flow meter assembly ( 10 ) and receiving the vibrational response, with the vibratory flow meter ( 100 ) being characterized by: the meter electronics ( 20 ) being 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 ), 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 component, the measured two-phase density, and the computed drive power, and combine the density compensation factor with the measured two-phase density to provide a compensated two-phase density.
