1. A system comprising:
- a liquid fraction probe configured to measure a liquid fraction of a flow of fluid that includes a first liquid, a second liquid, and a gas;
a vibratable flowtube configured 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
one or more processing devices connected to access the sensor signal and to access the measured liquid fraction, the one or more processing devices being configured to determine a corrected liquid fraction based on the sensor signal and the measured liquid fraction.

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 an individual flow rate of each phase within a multi-phase flow through the flowtube.
