| 摘要 |
<p>The invention concerns a device for sampling gas circulating in a pipe (24), means for regulating pressure (26) being installed on said pipe. Said sampling device is characterised in that it comprises: a sensor (28) for measuring a characteristic of said gas; a sampling point (30) and a discharge point (32) for a gas sample, located on either side of the pressure regulating means (26), at least an inlet or choke for the upstream flow (34), mounted between the sampling point (30) and the sensor input (28); an outlet (32), or a choke for the downstream flow mounted between the sensor output and the discharge point (32) for a gas sample which has circulated in the sensor.</p> |
