1. A system comprising:
- a gas void fraction sensor operable to measure a gas void fraction in a flow of fluid;
a flowmeter comprising;
a vibratable flowtube to receive the flow of fluid;
a driver connected to the flowtube and operable to impart motion to the flowtube;
a sensor connected to the flowtube and operable to sense the motion of the flowtube and generate a sensor signal; and
a controller connected to receive the sensor signal from the sensor and to receive the measured gas void fraction from the gas void fraction sensor, the controller being operable to determine a first flow rate of a first phase within the flow of fluid based on the measured gas void fraction received from the gas void fraction sensor, and determine a second flow rate of a second phase within the flow of fluid based on the measured gas void fraction received from the gas void fraction sensor.

Abstract
A flowmeter is disclosed. The flowmeter includes a vibratable flowtube, and a driver connected to the flowtube that is operable to impart motion to the flowtube. A sensor is connected to the flowtube and is operable to sense the motion of the flowtube and generate a sensor signal. A controller is connected to receive the sensor signal. The controller is operable to determine a first flow rate of a first phase within a two-phase flow through the flowtube and determine a second flow rate of a second phase within the two-phase flow.
