A measuring system and a method for measuring particle velocity and/or particle velocity distribution and/or size and/or particle size distribution
Measuring systems and methods measure particle velocity and/or particle velocity distribution and/or particle size or particle size distribution. The measuring system includes a filter for filtering collected signals which is arranged to pass signals at a relevant frequency band or at relevant frequency bands. The relevant frequency band or frequency bands are arranged to correspond to a frequency band or frequency bands defined by frequencies which exist in consequence of one or more process equipment or a process occurrence affecting to the medium flow.
