Abstract

Dispositif de mesure du débit d'un liquide, ou d'un paramètre correspondant, tel que profondeur ou vitesse moyenne d'écoulement de ce liquide, et surface libre dans un canal. Il comporte deux transducteurs à ultrasons 7, 8 fonctionnant alternativement comme émetteur et comme récepteur, formant entre eux un parcours de mesure 9, ainsi qu'un circuit de mesure déterminant les temps de propagation des ondes ultrasonores dans deux directions. Le parcours de mesure 9 présente une composante en direction verticale et est en contact avec une surface d'impact (surface 5 du liquide) variant en hauteur avec la surface 5 de ce liquide. Un circuit de restitution détermine, par l'intermédiaire de la somme des inverses des deux temps de propagation, une fonction de l'angle d'inclinaison theta , et les grandeurs voulues. Applications : dispositifs de mesure pour installations hydrauliques. Appareils de mesure des niveaux des liquides.
