ABSTRACT:
According to the invention, the device for granulometric analysis of particles contained in fluids comprises a feeding channel and a receiving channel intended for passage of a fluid under investigation. The two channels communicate with each other through a nozzle. The ratio between the diameters of the nozzle and the receiving channel is in the range of 1/4 to 1/7. The receiving channel is provided with transparent windows for passage of a light flux emitted by a lighting means through the fluid in that channel. The device further includes a light-sensitive means to receive light reflected from particles contained in the fluid.
