Vibratory flow meter and method for correcting for entrained gas in a flow material

A vibratory flow meter (100) for correcting for entrained gas in a flow material, comprising:

• a flow meter assembly (10) configured to generate a vibrational response for the flow material;
• a bubble size sensor (50) configured to generate a bubble measurement signal for the flow material;
• and
• meter electronics (20) coupled to the flow meter assembly (10) and to the bubble size sensor (50) and configured to receive the vibrational response and the bubble measurement signal, determine a bubble size of bubbles in the flow material using at least the bubble measurement signal, determine one or more flow characteristics of the flow material using at least the vibrational response, and generate an alarm if the bubble size exceeds a predetermine size threshold, with the alarm indicating that one or more flow characteristics have exceeded a predetermined measurement tolerance.

A method of correcting for entrained gas in a flow material in a vibratory flow meter, the method comprising:

• determining a bubble size of bubbles in the flow material using at least a vibrational measurement of the flow material;
• generating a vibrational response by vibrating a flow tube assembly;
• and
• determining one or more flow characteristics using at least the vibrational response and the bubble size.
