1. Process for measuring the dust content by weight of gaseous fluids, in which a sample (2) of the fluids, of which the dust content by weight is to be determined, is extracted continuously and isokinetically, and in which the extracted fluids are passed through a filter (10) continuously for a specific period repeated at regular interval, characterized in that the filter (10) is weighed during these intervals, in that, during the weighing these intervals, in that, during the weighing of the filter, the extracted fluids are discharged through a pipe which bypasses the filter, and in that the weight of dust relating to each extraction period is deduced from the values of the successive weighings of the increasingly laden filter. |
