Abstract

Procédé pour mesurer le débit massique d'un gaz liquide, extrait par pompage d'une citerne et amené à travers un emplacement de mesure à un appareil consommateur. L'écoulement est étranglé à l'emplacement de mesure 4, la mesure est effectué suivant la loi connue : M = m- alpha .A D 2Root ;2Q- DELTA P dans laquelle : M = débit manique par unité de temps; m = rapport d'ouverture de l'emplacement d'étranglement; AD = section d'écoulement à l'emplacement d'étranglement; alpha = coefficient de débit; Q = densité du liquide; DELTA p = perte de pression effective; la pression de refoulement du liquide est supérieure à sa tension de vapeur augmentée de la perte de pression maximale momentanée à l'emplacement d'étranglement, et la relation entre la température et la densité du liquide est prise en considération par une mesure de température au moyen d'un semi-conducteur 13, dont la caractéristique de résittance en fonction de la température est accordée sur l'allure de densité du liquide mesuré.
