1. A system comprising:
- a liquid fraction probe configured to measure a liquid fraction in 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 an apparent density or an apparent flowrate of the flow of fluid based on the received sensor signal, and correct the apparent density or the apparent flowrate based, at least in part, on the liquid fraction to generate a corrected density or a corrected flowrate.

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.

11. A transmitter comprising:
-
one or more processing devices; and a storage storing instructions that, when executed by the one or more processing devices, cause the one or more processing devices to perform the following; access a liquid fraction measured by a liquid fraction probe configured to measure a liquid fraction in a flow of fluid that includes a first liquid, a second liquid, and a gas; impart motion to a vibratable flowtube using a driver connected to the flowtube, the flowtube being configured to receive the flow of fluid; receive a sensor signal from a sensor connected to the flowtube and operable to sense the motion of the flowtube and generate the sensor signal; determine an apparent density or an apparent flowrate of the flow of fluid based on the received sensor signal; and correct the apparent density or the apparent flowrate based, at least in part, on the liquid fraction to generate a corrected density or a corrected flowrate. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
