Abstract

Dispositif de prélèvement de fuite de gaz avec débit élevé Dispositif de détection quantitative de fuite (201) d’un gaz d’intérêt comprenant : une conduite d’aspiration (101) ayant une entrée d’aspiration amont (102) destinée à être amenée au voisinage d’une région au sein de laquelle on souhaite détecter une fuite, un appareil de ventilation (104) générant un flux de gaz (107) dans la conduite d’aspiration ayant un débit supérieur à 300m3/H circulant depuis l’entrée d’aspiration amont vers l’aval de la conduite, en aval de l’appareil de ventilation, un organe de prélèvement. Figure pour l’abrégé : Fig. 1
