Abstract
A simple automatic system of measuring liquid particle size distribution has been deve loped. The system was attached to a microcomputer exclusively used as a convenient method of measuring liquid particle size.
This system, of a front-end computer and a host computer, is based on the distributed multi-processor system. The front-end computer gets the peak value of an impulse from a measuring circuit, calculates the value of the particle size and displays it. The host computer calculates and displays the size distribution using data transported from the front-end computer. By this method, liquid particle size is measured in real time, and size distribution is displayed promptly.
To check the system, the size distributions of water droplets of from 52 to 2300μm in size produced by a spinning-disk atomizer and the mist produced by a pressure nozzle were measured. The results of this measurement showed that the measured sizes using this method agreed with the results obtained by the immersion liquid method.
