Abstract
Un mode de réalisation de linvention concerne un système permettant de calculer un débit dun débitmètre à laide de plusieurs modes. Ledit système comprend un moyen permettant de calibrer le débitmètre pour un certain nombre de modes voulu. Ce système comprend également un moyen permettant de déterminer une densité de matière traversant le débitmètre, qui est associée à chaque mode. De plus, le système comprend un moyen conçu pour déterminer l'effet de débit sur la densité, pour chaque mode désiré. Ce système comprend finalement un moyen pour calculer un débit en fonction de la densité et de l'effet de débit sur les valeurs de densité, pour chaque mode voulu.
