Abstract

APPAREIL DE MESURE DE LA VITESSE D'ECOULEMENT D'UN GAZ. CET APPAREIL EST DU TYPE COMPORTANT DEUX SONDES ULTRASONORES 4 ET 5 DISPOSEES EN FACE L'UNE DE L'AUTRE ET TRANSMETTANT DES IMPULSIONS SUIVANT UN TRAJET AVAL ET UN TRAJET AMONT OBLIQUES PAR RAPPORT A LA VITESSE D'ECOULEMENT. LE DISPOSITIF DE COMMUTATION QUI PERMET D'ETABLIR CES DEUX TRAJETS EST AGENCE POUR EFFECTUER UNE COMMUTATION DES SONDES AUSSI BIEN A L'EMISSION QU'A LA RECEPTION, LES SIGNAUX DE COMMANDE DE LA COMMUTATION (DIVISEUR DE FREQUENCE 3) ETANT DEPHASES PAR RAPPORT AUX IMPULSIONS D'EMISSION. DE PREFERENCE LA COMMUTATION A L'EMISSION S'EFFECTUE PAR RELAIS 71-72 ET 81-82.
