DEVICE DETERMINING SIZE AND NUMBER OF PARTICLES IN LIQUID Russian patent published in 2000 - IPC

FIELD: instrumentation, automatic measurement of size and number of particles in flow medium, in spaces of technological apparatuses to evaluate quality and efficiency of technological processes. SUBSTANCE: operational principle of device consists in scanning of image of disperse medium passing over pipe-line with the use of multielement regular light guide, multielement non-regular light guide, optical focusing system and registering element based on matrix of charge-coupled device. Multielement nonregular light guide performs function of transmission of pulse of optical radiation to expose analyzed medium to radiation and multielement regular light transmits reflected radiation on to focusing system. Time of exposure of analyzed medium can be set by means of source of pulse illumination. Insertion of this element makes it possible to make disperse analysis directly in flow of liquid. Microcomputer used in mix of device processes automatically and identifies disperse systems with the help of analog-to-digital converter. EFFECT: usage of light guide in structural design of device makes it feasible to conduct disperse analysis in places difficult of access. 1 dwg
