Abstract

La présente invention concerne un débitmètre magnétique (102) qui comprend un ensemble tube d'écoulement (120) et un générateur de courant bidirectionnel programmable (132). L'ensemble tube d'écoulement (120) reçoit l'écoulement de fluide (104) et comprend une bobine (126A/B) et un capteur de force électromotrice (EMF) (124A/B). La bobine est conçue pour produire un champ magnétique dans tout l'écoulement de fluide (104) en réponse à un courant de bobine. Le capteur EMF (124A/B) est conçu pour détecter une force électromotrice dans tout l'écoulement de fluide qui est proportionnel au débit et générer une sortie indiquant la force électromotrice induite. Le générateur de courant (132) comprend un générateur de profils (144) qui émet des commandes de profil, un amplificateur de puissance (142) et un dispositif de commande (140). Le dispositif de commande (140) est conçu pour commander l'amplificateur de puissance (142) pour générer des impulsions de courant de bobine formant le courant de bobine qui se déplacent à travers la bobine (126A/B) dans des directions alternées. Chaque impulsion de courant de bobine a un profil de courant qui est basé sur une commande de profil correspondante.
