Title (EN) CALIBRATION DEVICE AND SENSITIVITY DETERMINING DEVICE FOR VIRTUAL FLOW METER, AND ASSOCIATED METHODS
(FR) DISPOSITIF D'ÉTALONNAGE ET DISPOSITIF DE DÉTERMINATION DE SENSIBILITÉ DESTINÉ À UN DÉBITMÈTRE VIRTUEL, ET PROCÉDÉS ASSOCIÉS
Abstract:
(EN) The present disclosure relates to a calibration device and a sensitivity determining device for a virtual flow meter, and corresponding methods. The present disclosure relates to a calibration device for calibrating a virtual flow meter of a production system, and 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, and 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. The present disclosure further relates to corresponding methods.
(FR) La présente invention concerne un dispositif d'étalonnage et un dispositif de détermination de sensibilité destinés à un débitmètre virtuel, et des procédés correspondants. La présente invention concerne un dispositif d'étalonnage servant à étalonner un débitmètre virtuel d'un système de production, et le système de production comprend des éléments permettant de transférer un fluide, le débitmètre virtuel étant conçu pour estimer un débit du fluide sur la base de valeurs de propriété des éléments et de valeurs de paramètres variables des éléments, et le dispositif d'étalonnage comprend un module de détermination de sensibilité conçu pour calculer une première sensibilité, la première sensibilité étant utilisée pour indiquer un degré de changement des valeurs des paramètres variables par rapport à une perturbation des valeurs de propriété ; et un module d'étalonnage conçu pour étalonner le débitmètre virtuel en fonction de la première sensibilité. La présente invention concerne en outre des procédés correspondants.
