SYSTEM OF GRANULOMETRIC ANALYSIS OF LIQUID DISPERSION MEDIA Russian patent published in 2017 - IPC G01N15/02 

FIELD: measuring equipment.

SUBSTANCE: system for granulometric analysis of liquid dispersion media contains a light source, a camera and a neural network block. The test material is transferred from the process tank 1 to the flow measuring chamber 3, where a probe collimated light beam is introduced. The pattern of the radiation scattered by the medium is photographed by a digital camera 10. In the feature sampling module 11, the necessary data for neural network data conversion is selected in the neural network block 12. The training vector is fed to the block 12 from the objective analysis unit 14 based on the sedimentometric or microscopic method of granulometric analysis. The neural network block is trained at the initial graduation, and also in cases when the light scattering pattern differs greatly from the already known ones. The described system is able to perform express analysis in flowing conditions and has increased metrological reliability due to periodic calibration and additional training of the system during operation.

EFFECT: increased accuracy and metrological reliability of the system for the express determination of grain-size composition due to periodic automatic calibration and additional training of the system during operation.
