Title (EN) MULTIVARIABLE PROCESS FLUID FLOW DEVICE WITH ENERGY FLOW CALCULATION
(FR) DISPOSITIF DE CIRCULATION DE FLUIDE DE PROCESS MULTI-VARIABLE AVEC CALCUL DE FLUX D’ÉNERGIE
Abstract: front page image
(EN)A process fluid flow device (12) includes a power supply module (24), a process communication module (20), a processor (26) and measurement circuitry (28). The process communication circuitry (20) is coupled to the power supply module (24) and to the processor (26). The measurement circuitry (28) is operably coupleable to plurality of process variable sensors to obtain an indication of differential pressure, static pressure and process fluid temperature. The processor (26) is configured to compute process fluid mass flow, and to use the static pressure and process fluid temperature to obtain an energy per unit mass value relative to the process fluid and to provide an energy flow indication.
(FR)L'invention concerne un dispositif (12) de circulation de fluide de process comprenant un module (24) d’alimentation, un module (20) de communication de process, un processeur (26) et des circuits (28) de mesure. Les circuits (20) de communication de process sont couplés au module (24) d’alimentation et au processeur (26). Les circuits (28) de mesure peuvent être couplés fonctionnellement à une pluralité de capteurs de variables de process pour obtenir une indication de pression différentielle, de pression statique et de température du fluide de process. Le processeur (26) est configuré en vue de calculer le débit massique du fluide de process et d’utiliser la pression statique et la température du fluide de process pour obtenir une valeur d’énergie par unité de masse relative au fluide de process et donner une indication de flux d’énergie.
