Claim Text:
1. A Coriolis mass flow meter comprising a controller configured to: determine an expected liquid density of an oil fluid flow at an operating temperature as determined by measure the density of the oil fluid flow; compare the expected liquid density of the oil fluid flow to the measured density of the oil fluid flow; determine, based at least in part on the expected liquid density compared to the measured density of the oil fluid flow, a phase status of the oil fluid flow, wherein when the measured density of the oil fluid flow is less than the expected liquid density of the oil fluid flow, the phase status of the oil fluid flow comprises an oil/gas fluid flow; determine, when the measured density of the oil fluid flow is less than the expected liquid density of the oil fluid flow, a volumetric flow of an oil portion of the oil/gas fluid flow using the expected liquid density of the oil fluid flow; and determine, when the measured density of the oil fluid flow is less than the expected liquid density of the oil fluid flow and based on a density ratio as determined by in the specification, a volumetric flow of a gas portion of the oil/gas fluid flow.
