Method of measuring density properties of a particle distribution

摘要

A method and a device for measuring density properies of a particle distribution, in which method a first parameter relating to the particle distribution is measured at a first measuring point ( 302 ), at least part of the flow that passed through the first measuring point is guided to the second measuring point ( 304 ), a second parameter relating to the particle distribution is measured at a second measuring point ( 305 ), and said first and second parameters relating to the particle distribution are used to determine at least one density property of the particle distribution of the original flow ( 306 ).
