Abstract
Montage électronique pour déterminer par ultra-sons des grandeurs physiques, notamment la vitesse d'écoulement d'un fluide, qui comprend un détecteur de phase 15 qui détermine la position de phase d'un signal retardé d'arrivée S14 et un dispositif de réglage 18, agissant sur un dispositif temporisateur d'arrivée 13. L'invention prévoit un dispositif de remise à zéro 100, qui entre en action lorsque la tension de sortie S19 de l'intégrateur 64 atteint une valeur limite prédéterminée C1, G2 positive et/ou négative et qui amène alors la tension de sortie à s'annuler. Application : mesures de vitesse d'écoulement d'un fluide.
