ULTRASONIC WAY OF CONTROL OF THE STRUCTURE OF DISPERSE MEDIA Russian patent published in 2018 - IPC G01N29/11 

FIELD: measuring equipment.

SUBSTANCE: application: to determine the structure of disperse media. Invention consists in the fact that the vessel is filled with a dispersed medium, which is irradiated with a longitudinal ultrasonic wave at a frequency at which the length of wave λ exceeds the size of particles R, and then the value of the pulse A₀, that have passed through the dispersed phase (liquid without particles) is recorded, then the particles are introduced, the magnitude of the amplitude A_n of pulses that have passed the distance L through the system under study and the times t_n are recorded, the difference A₀-A_n of the values of the pulses at different times t_n are determined, the structure of the disperse system is judged on the basis of array A₀-A_n/A₀.

EFFECT: technical result: increase in the efficiency of determining the structure of disperse media, the reliability of measurements and ensuring the possibility of monitoring a wide class of disperse systems.
