An ultrasonic gas concentration measuring equipment (100) comprising a duct (102) for passing a gas of which the concentration is measured, an ultrasonic transmitter/receiver (118) secured in the duct, a reflector (122) secured in the duct oppositely to the ultrasonic transmitter/receiver, and a switch (124) for switching the operating mode of the ultrasonic transmitter/receiver between transmitting mode and receiving ode. The ultrasonic gas concentration measuring equipment (100) further comprising a calibration gas source (114) for supplying a calibration gas having known components and compositional ratio to the duct, temperature sensors (116, 120) for measuring the temperature of the calibration gas passing through the duct, means (126) for operating the propagation time of ultrasonic wave traveling through the duct, and means (126) for calibrating the reference distance between the ultrasonic transmitter/receiver and the reflector based on the operational results of the propagation time operating means.

L'invention concerne un appareil (100) de mesure de la concentration de gaz par ultrasons. Cet appareil comprend une conduite (102) pour laisser passer un gaz dont on mesure la concentration, un émetteur /récepteur (118) à ultrasons, fixé dans la conduite, un réflecteur (122) fixé dans la conduite en regard du récepteur /émetteur, et un interrupteur (124) pour assurer la commutation du mode de fonctionnement de l'émetteur/récepteur entre le mode d'émission et le mode de réception. L'appareil de mesure de la concentration du gaz par ultrasons (100) comprend, en outre, une source de gaz d'étalonnage (114) pour fournir un gaz d'étalonnage comportant des composants connus et un rapport de composition à la canalisation, des capteurs de température (116, 120) pour mesurer la température du gaz d'étalonnage passant dans la canalisation, des moyens (126) pour gérer le temps de propagation de l'onde ultrasonore se déplaçant dans la canalisation, et des moyens (126) pour étalonner la distance de référence entre l'émetteur/récepteur ultrasonore et le réflecteur en fonction des résultats opérationnels du moyen gérant le temps de propagation.
