Title
(EN) USING A DENSITY MEASUREMENT OF A FLUID TO VERIFY A VAPOR PRESSURE
(FR) UTILISATION D'UNE MESURE DE DENSITÉ D'UN FLUIDE POUR VÉRIFIER UNE PRESSION DE VAPEUR
Abstract
(EN)
A meter electronics (20) for using a density measurement of a fluid to verify a vapor pressure is provided. The meter electronics (20) includes a processing system (200) communicatively coupled to a meter assembly (10) having the fluid, the processing system (200) is configured to determine a vapor pressure of the fluid by detecting a phase change of the fluid in the meter assembly (10), measure a density of the fluid based on a resonant frequency of the meter assembly (10), derive a vapor pressure from the measured density, and compare the determined vapor pressure with the derived vapor pressure.

L'invention concerne une électronique de compteur (20) permettant d'utiliser une mesure de densité d'un fluide pour vérifier une pression de vapeur. L'électronique de compteur (20) comprend un système de traitement (200) couplé en communication avec un ensemble compteur (10) comprenant le fluide, le système de traitement (200) étant conçu pour déterminer une pression de vapeur du fluide par la détection d'un changement de phase du fluide dans l'ensemble compteur (10), mesurer une densité du fluide en fonction d'une fréquence de résonance de l'ensemble compteur (10), dériver une pression de vapeur à partir de la densité mesurée, et comparer la pression de vapeur déterminée à la pression de vapeur dérivée.
