Abstract

L'invention concerne les dispositifs de mesures de débit dans des canalisations au moyen de deux sondes acoustiques. Ce débitmètre, grâce à une disposition particulière des sondes, permet de faire des mesures de débit indépendantes de la viscosité du fluide. Dans ce but, les sondes sont disposées sur une droite ne recoupant pas l'axe de la canalisation.
