Abstract

L'invention concerne les débitmètres acoustiques. Elle se rapporte à un débitmètre qui comprend deux transducteurs acoustiques qui transmettent des salves d'impulsions alternativement vers l'amont et vers l'aval. Les signaux reçus sont amplifiés et subissent un filtrage sur une bande étroite, et l'information de phase est préservée. Le déphasage est proportionnel à la vitesse du courant de fluide mesurée. Application à la mesure des débits dans les canalisations.
