Abstract
The invention relates to a process for the continuous determination of the dust content of flowing media with the isokinetic flow sampling with the separation of the dust or aerosols by cake filtration on a filter and the measurement of the pressure drop at the filter to determine its degree of clogging. To this end the time cycle of the quantity of dust separated on the filter is determined by the measurement of the pressure loss at the filter of an isokinetically operating sampling system. To find the dust load, this quantity of dust is related to the partial quantity of gas extracted isokinetically during the period concerned.
