Abstract

L'invention sert à déterminer le débit des milieux liquides diélectriques ou faiblement conducteurs au moyen de débitmètres électromagnétiques. Selon l'invention, pour déterminer le débit d'un liquide on règle l'intensité du champ électromagnétique en fonction de la valeur actuelle du débit du liquide régulé et/ou de sa dérivée par rapport au temps. L'intensité est réglée en partant du principe d'atteindre un minimum d'intensité du champ électromagnétique excité avec une valeur déterminée de l'erreur du signal de données pour le débit actuel du liquide régulé.
