Abstract
a. Anémomètre à fil chaud, destiné à mesurer la vitesse d'écoulement de gaz et de liquides, en particulier de l'air d'aspiration de moteurs à combustion interne, comportant une ou plusieurs résistances de mesures sensibles à la température, dont au moins une est chauffée. b. Anémomètre caractérisé en ce qu'il comporte une couche isolante de la chaleur appliquée sur la face, tournée vers le courant, de la résistance chauffée. c. L'invention s'applique à la mesure de la vitesse d'écoulement des gaz et des liquides.
