Abstract

Montage pour la mesure de la vitesse d'écoulement d'un fluide, comportant deux résistances thermométriques (16, 17) baignées dans le fluide et munies de résistances additionnelles (50, 68), ces résistances (16, 17, 50, 68) constituant des parties de couplages thermométriques (30, 31) alimentés par la sortie (40) d'un amplificateur.
