The measuring device comprises, for measuring multi phase mixture, a vibratory- type transducer and a measuring device electronics electrically coupled with the vibratory- type transducer. The transducer includes at least one measuring tube inserted into the course of the pipeline. An exciter arrangement acts on the measuring tube for causing the at least one measuring tube to vibrate . A sensor arrangement senses vibrations of the at least one measuring tube and delivers at least one oscillation measurement signal representing oscillations of the measuring tube. Further, the measuring device electronics delivers an excitation current driving the exciter arrangement. The measuring device is adapted to compensating measurement errors, induced due to the presence of multi phase mixture, based on a moving resonator model (MRM) .
Dispositif de mesure comprenant un transducteur de type vibratoire servant à mesurer un mélange multiphasique et des composants électroniques couplés électriquement au transducteur de type vibratoire. Le transducteur comporte au moins un tube de mesure inséré le long d~une conduite. Un ensemble excitateur exerce une action sur ledit au moins un tube de mesure pour le faire vibrer. Un ensemble détecteur détecte les vibrations dudit au moins un tube de mesure et fournit au moins un signal de mesure d~oscillations représentant les oscillations dudit au moins un tube de mesure. Les composants électroniques du dispositif de mesure délivrent en outre un courant d~excitation pour alimenter l~ensemble excitateur. Le dispositif de mesure est conçu pour corriger les erreurs de mesure dues à la présence du mélange multiphasique à partir d~un modèle de résonateur mobile (MRM).
