FLOW METER SYSTEM AND METHOD FOR MEASURING FLOW CHARACTERISTICS OF A THREE PHASE FLOW

摘要

A vibratory flow meter (5) for measuring flow characteristics of a three phase flow is provided according to the invention. The vibratory flow meter (5) includes a meter assembly (10) including pickoff sensors (105, 105') and meter electronics (20) coupled to the pickoff sensors (105, 105'). The meter electronics (20) is configured to receive a vibrational response from the pickoff sensors (105, 105'), generate a first density measurement of the three phase flow using a first frequency component of the vibrational response, and generate at least a second density measurement of the three phase flow using at least a second frequency component of the vibrational response. The at least second frequency component is a different frequency than the first frequency component. The meter electronics (20) is further configured to determine one or more flow characteristics from the first density measurement and the at least second density measurement.
