(FR) CORRECTION POUR DES ANALYSEURS D'EAU ENTRAÎNÉS PAR UN GAZ
Abstract
(EN)
An apparatus (10) for measuring a water content in a multiphase fluid flow stream is provided. The apparatus (10) comprises a measurement section (30) configured to obtain a series of electrical measurements of the multiphase fluid flow stream over a first predetermined time interval, and determine a minimum electrical measurement Fmin_baseline from the series of electrical measurements (501). The measurement section also is configured to calculate a running average of the frequency (Fmin_gas_pattern) from the series of electrical measurements indicative of a change in a gas flow pattern of the multiphase fluid flow stream over a second predetermined time interval (505). The measurement section further is configured to calculate a corrected electrical measurement F_calc_WC for determining the water content in the multiphase fluid flow stream by subtracting the minimum electrical measurement Fmin_gas_pattern from the minimum electrical measurement Fmin_baseline (507).

L'invention porte sur un appareil (10) pour mesurer une teneur en eau dans un courant d'écoulement de fluide polyphasé. L'appareil (10) comprend une section de mesure (30) configurée de façon à obtenir une série de mesures électriques du courant d'écoulement de fluide polyphasé pendant un premier intervalle de temps prédéterminé, et à déterminer une mesure électrique minimale (Fmin_fondamentale) à partir de la série de mesures électriques (501). La section de mesure est également configurée de façon à calculer une moyenne en cours de la fréquence (Fmin_gaz_motif) à partir de la série de mesures électriques indicatives d'un changement dans un motif d'écoulement de gaz du courant d'écoulement de fluide polyphasé au cours d'un deuxième intervalle de temps prédéterminé (505). La section de mesure est de plus configurée de façon à calculer une mesure électrique corrigée (F_calc_WC) pour déterminer la teneur en eau dans le courant d'écoulement de fluide polyphasé par soustraction de la mesure électrique minimale (Fmin_gaz_motif) de la mesure électrique minimale (Fmin_fondamentale) (507).
