Abstract

Dispositif pour mesurer le débit d'un fluide circulant dans une canalisation au moyen d'ondes acoustiques. Le débitmère selon l'invention comprend au moins deux sondes placées en regard de part et d'autre d'un fourreau dont le diamètre est égal à celui de la canalisation. Une chambre annulaire, en communication avec le liquide de la canalisation, permet de loger les sondes. Le fourreau comporte des zones à paroi très minces pour faciliter la transmission des ondes acoustiques. L'invention se prête particulièrement bien à la réalisation de débitmères acoustiques destinés à des circuits de liquides cryogéniques.
