Abstract: An electro-optical technique is described for the measurement of the size distribution of particles from 2.5 μm upwards, in a flow. The apparatus utilizes a white light source, a photodiode array and particle-sizing electronics. The data acquisition system is a multichannel analyser or a microcomputer. This device is an extension to the flow case of a previous device designed for static size analysis, and a critical comparison with size acquisition systems commercially available is given. Shape of particles and outline of waveform during particle detection are discussed.
