Abstract

Deux transducteurs ultrasoniques 3 et 4, montés sur un parcours de mesure pour fluide 2, coopèrent avec un organe emetteur 5 et un organe de mesure 6. L'émetteur excite périodiquement et simultanément les deux transducteurs. L'organe de mesure établit des impulsions de mesure qui représentent la différence des temps de propagation des impulsions ultrasonores entre les deux transducteurs. Un capteur de la température du fluide commande la fréquence d'un oscillateur. Un multiplicateur coopère avec les circuits précédents pour définir des impulsions de comptage dont la fréquence moyenne est égale au produit de la durée des impulsions de mesure par la fréquence des oscillations de l'oscillateur. Application notamment aux mesures thermiques dans les liquides.
