METHOD FO MEASUREMENT OF LIQUID VISCOSITY Russian patent published in 1996 - IPC

FIELD: measurement of physicochemical properties of liquid media. SUBSTANCE: method consists in submergence of spherical probe in liquid, measurement of coordinate h_i at time moment t_i in vertical component of probe motion trajectory and calculation of average value of vertical components of probelmotion velocities v_i at points corresponding to coordinates h_i. Determination of viscosity is performed through calculations taking into account density of liquid under test. EFFECT: enhanced efficiency. 1 dwg
