Abstract

A vibratory flow meter (100) for correcting for entrained gas in a flow material is provided. The vibratory flow meter (100) comprises 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). The meter electronics (20) is 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 the bubble size.

Description

technical field [0001] The present invention relates to a vibratory flow meter and method, and more particularly to a vibratory flow meter and method for correcting for entrained gas in a flowing material. Background technique [0002] Vibtating conduit sensors, such as Coriolis mass flow meters and vibrating densitometers, typically work by detecting the motion of a vibrating conduit containing a flowing material. Properties related to the substance in the pipeline, such as mass flow, density, etc., may be determined by processing measurement signals received from displacement sensors associated with the pipeline. The modes of vibration of a system filled with a vibrating mass are generally affected by the combined mass, stiffness and damping properties of the contained pipes and the matter contained in the pipes. [0003] A typical Coriolis mass flow meter includes one or more pipes connected in a line in a pipeline or other transportation system and conveying materials s...
