Abstract

L'invention concerne un débitmètre massique/densimètre de Coriolis comprenant au moins un tuyau de mesure (11) qui est traversé par une substance à deux phases ou davantage pendant son fonctionnement. Un moyen de support (12) du débitmètre massique/densimètre de Coriolis est fixé sur une extrémité côté admission et une extrémité côté évacuation du tuyau de mesure (11), ce qui serre le tuyau de mesure de sorte qu'il puisse vibrer. Lors de son fonctionnement, le tuyau de mesure (11) vibre mécaniquement, en particulier il effectue des vibrations de flexion, sous l'action d'un système d'excitation (13). Le débitmètre massique/densimètre de Coriolis selon l'invention comprend également des moyens (141, 142) pour générer des signaux de mesure (xs1, xs2) qui représentent des vibrations côté admission et côté évacuation du tuyau de mesure (11). Un système électronique d'évaluation (2) génère une valeur intermédiaire (X'm), à partir desdits signaux de mesure (xs1, xs2), cette valeur intermédiaire représentant un débit massique déterminé de manière provisoire, et ledit système électronique d'évaluation génère en outre une deuxième valeur intermédiaire (X2), à partir desdits signaux de mesure (xs1, xs2), en particulier à partir d'une deuxième valeur de mesure (Xς) qui est également générée dans le système électronique d'évaluation (2) et qui représente une densité de la substance, ladite deuxième valeur intermédiaire représentant une mesure de la proportion d'une phase de la substance. La deuxième valeur intermédiaire (X2) est utilisée pour déterminer une valeur de correction (XK) pour la première valeur intermédiaire (X'm), cette valeur de correction (XK) étant sélectionnée parmi une pluralité de valeurs prédéterminées stockées dans une mémoire-table (56), au moyen de la deuxième valeur intermédiaire (X2). Le système électronique d'évaluation (2) génère en outre une valeur de mesure (Xm) qui représente un débit massique, au moyen de la première valeur intermédiaire (X'm) et de la valeur de correction (XK).
