A pipeline system of a process facility has a plurality of equipments, the equipments including at least one pipeline for providing a channel for a fluid of a process to flow. The process of the process facility is controlled by a process control system. The equipments also include at least one device for measuring a process variable of the fluid. The device comprises a sensor element for sensing a predetermined process variable of the fluid flowing in the pipeline to output a signal containing information about the process variable being measured and containing information about the fluid flowing in the pipeline. The device further includes a first filter to pass a first component of the signal containing the information of the process variable and a second filter to pass a second component of the signal containing the information about the fluid flowing in the pipeline. A first processor processes the first component of the signal to output the process variable to the process control system to control the process. A second processor processes the second component of the signal in a flow model of the pipeline system to output advisory information indicating imminent failure of the equipment when detected by said processing by the second processor.
Un système de pipeline d'un processus industriel possède plusieurs équipements y compris au moins un pipeline d'écoulement de fluide. Le processus industriel est commandé par un système de commande. Les équipements incluent au moins un dispositif de mesure d'une variable du fluide. Le dispositif comprend un élément détecteur qui permet de détecter une variable prédéterminée du fluide s'écoulant dans le pipeline afin de produire un signal de sortie contenant des informations relatives à ladite variable que l'on désire mesurer et contenant des informations relatives au fluide s'écoulant dans le pipeline. Le dispositif comprend en outre un premier filtre de passage d'une première composante du signal contenant les informations relatives à la ladite variable ainsi qu'un second filtre de passage d'une seconde composante du signal contenant les informations relatives au fluide s'écoulant dans le pipeline. Un premier processeur traite la première composante du signal afin de produire en sortie la variable du processus et la fournir au système de commande du processus. Un second processeur traite la seconde composante du signal dans un modèle d'écoulement du système de pipeline afin de sortir des informations conseils indiquant une défaillance imminente de l'équipement détectée par le second processeur.
