Calibration apparatus and sensitivity determining module for virtual flow meter and associated methods

Abstract:

The present disclosure relates to a calibration device for calibrating a virtual flow meter of a production system. The production system includes components for transferring fluid, where the virtual flow meter is configured to estimate a flow rate of the fluid based on property values of the components and values of variable parameters of the components. The calibration device includes a sensitivity determining module configured to calculate a first sensitivity, where the first sensitivity is used to indicate a degree of change of the values of the variable parameters relative to disturbance of the property values, and a calibration module configured to calibrate the virtual flow meter according to the first sensitivity.
