Abstract
A process is disclosed for determining properties of a flow tube and of a fluid flowing through the flow tube. One example of such a property is the density of the fluid flowing through the flow tube. To determine the properties, the process determines a measured mode shape based on pickoff signals received from a plurality of pickoffs. The process selects values for flow tube and fluid parameters. The process determines an estimated mode shape based on the values for the flow tube and fluid parameters. The process compares the measured mode shape and the estimated mode shape to determine an error for the values for the flow tube and fluid parameters. If the error for the values is within an error range, then the process determines the properties of the flow tube and of the fluid based on the estimated values. If the error for the values is not within the error range, then the process selects new values for the flow tube and fluid parameters.
