Abstract

Il est décrit le fait de vérifier si un mécanisme de résistance de champs magnétiques est correctement engagé dans une valvule de drainage ayant une unité de valvule ajustable, y compris une construction de rotation et une paire déléments magnétiques primaires pour la programmation de lunité de valvule. À laide dune boîte à outils, une détermination est faite à savoir si le mécanisme de résistance de champs magnétiques est engagé correctement. Un avis est généré pour déterminer si le mécanisme de résistance de champs magnétiques engagé correctement et/ou sil nest pas engagé correctement d'après : (i) une position angulaire mesurée dun élément magnétique primaire dune paire de ce dernier par rapport à une direction de débit de fluide à travers la valvule; et/ou (ii) une séparation de distance mesurée entre des parties centrales respectives de la paire déléments magnétiques primaires.
