Title
(EN) NON-INTRUSIVE PROCESS FLUID PRESSURE MEASUREMENT SYSTEM
(FR) SYSTÈME DE MESURE NON INTRUSIVE DE PRESSION DE FLUIDE DE PROCESSUS
Abstract
(EN)
A system for non-intrusively measuring process fluid pressure within a process fluid conduit (202) is provided. The system includes a measurement bracket (200) configured to couple to an external surface of the process fluid conduit (202). The measurement bracket generates a variable gap based on deformation of the process fluid conduit (202) in response to process fluid pressure therein. A gap measurement system (220, 260, 262) is coupled to the measurement bracket (200) and provides an electrical signal based on a measurement of the variable gap. A controller (216) is coupled to the gap measurement system (220, 260, 262) and is configured to calculate and provide a process fluid pressure output based on the electrical signal and information relative to the process fluid conduit (202).

L'invention concerne un système de mesure non intrusive de la pression de fluide de processus à l'intérieur d'un conduit à fluide de processus (202). Le système comprend un support de mesure (200) conçu pour s'accoupler à une surface externe du conduit à fluide de processus (202). Le support de mesure génère un écart variable sur la base d'une déformation du conduit à fluide de processus (202) en réponse à une pression du fluide de processus à l'intérieur de celui-ci. Un système de mesure d'écart (220, 260, 262) est connecté au support de mesure (200) et produit un signal électrique sur la base d'une mesure de l'écart variable. Un contrôleur (216) est connecté au système de mesure d'écart (220, 260, 262) et il est conçu pour calculer et produire une sortie de pression de fluide de processus sur la base du signal électrique et des informations relatives au conduit à fluide de processus (202).
