A system for monitoring, diagnosing, and/or controlling a flow process uses one or more flow meters based on an array of pressure sensors. A signal processor outputs at least one of a flow signal, a diagnostic signal, and a control signal in response to the pressure signals from the pressure sensors. The flow signal indicates the at least one parameter of the fluid, the diagnostic signal indicates a diagnostic condition of a device in the flow process, and the control signal is effective in adjusting an operating parameter of at least one device in the flow process. The system may be arranged as a distributed control system (DCS) architecture for monitoring a plurality of flow meters based on array-processing installed at various locations throughout a flow process.

Cette invention concerne un système permettant de surveiller, de diagnostiquer et/ou de commander un processus d'écoulement, lequel système utilise un ou plusieurs débitmètres reposant sur un réseau de capteurs de pression. Un processeur de signaux émet un signal d'écoulement et/ou un signal de diagnostic et/ou un signal de commande en réponse aux signaux de pression émis par les capteurs de pression. Le signal d'écoulement indique le ou les paramètres du fluide tandis que le signal de diagnostic indique un état diagnostique d'un dispositif dans le processus d'écoulement. Quant au signal de commande, il permet de régler un paramètre de fonctionnement d'au moins un dispositif dans le processus d'écoulement. Ce système peut se présenter sous la forme d'une structure d'un système de commande réparti (DCS) permettant de surveiller une pluralité de débitmètres reposant sur un traitement de réseau et située à différents endroits dans un processus d'écoulement.
