摘要

A method of detecting an inaccurate flow rate measurement by a vibratory meter, and apparatus for detecting an inaccurate flow rate measurement by a vibratory meter? A method of detecting an inaccurate flow rate measurement by a vibratory meter is provided. The method includes flowing the fluid through the vibratory meter and measuring a flow rate and a fluid density with the vibratory meter, and calculating a fluid density change rate. The method also includes determining whether the measured flow rate is inaccurate based on a comparison between the measured density and a density reference, and a comparison between the density change rate and a density change rate reference.
