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.
