METHOD OF MEASUREMENT OF CONCENTRATION OF FERROMAGNETIC PARTICLES IN FLUID Russian patent published in 1997 - IPC

Abstract RU 2084887 C1

FIELD: chemical industry, test and control of concentration of ferromagnetic particles in fluid. SUBSTANCE: in compliance with proposed method fluid with ferromagnetic particles is put into cylindrical resonator in which oscillation HIIP is excited, where p is number of half-waves present along length of resonator. Resonator is placed into permanent magnetic field which direction is matched with axis of resonator and two values of split natural frequency are measured. Concentration of particles is found by difference of frequencies. EFFECT: increased authenticity of method. 2 dwg
