Abstract

Un compteur électronique (20) pour un débitmètre (5) est fourni selon le prototype de l'invention. Le compteur électronique (20) inclut une interface (201) pour la réception de la réponse vibratoire du débitmètre (5) et un système de traitement (203) en communication avec l'interface (201). La réponse vibratoire est une réponse à une vibration du débitmètre (5) à une fréquence substantiellement résonnante. Le système de traitement (203) est configuré pour recevoir la réponse vibratoire du débitmètre de l'interface (201), déterminer une fréquence (.oméga.0) de la réponse vibratoire, déterminer une réponse à la tension (V) et un courant d'attaque (I) de la réponse vibratoire, mesurer une caractéristique de persistance (.zêta.) du débitmètre (5), et déterminer le paramètre de rigidité (K) de la fréquence (.oméga.0), la réponse à la tension (V), le courant d'attaque (I) et la caractéristique de persistance (.zêta.).
