METHOD AND APPARATUS FOR DETERMINING A FLOW RATE ERROR IN A VIBRATING FLOW METER

摘要

A method for determining an error in a flow rate of a fluid flowing through a vibrating flow meter is provided. The method includes the step of receiving sensor signals from the vibrating flow meter. A first flow rate is determined using the sensor signals. A fluid density is determined. A fluid velocity is determined using the first flow rate, the fluid density, and a physical property of the flow meter. A flow parameter, V/p is calculated based on the fluid velocity and the density. A flow rate error is then determined based on the calculated flow parameter.
