FIELD: machine building.
SUBSTANCE: procedure for measuring viscosity of liquids is designed for control of liquids of high viscosity in chemical, food and other branches of industries. The procedure for measuring viscosity of liquid consists in effecting surface of liquid with a gas jet of alternate velocity and in generation of forced surface-mode waves. Further, there are changed and measured frequency of fluctuations of gas jet velocity. Velocity of gas jet is changed according to a harmonic law. There is measured phase-shifting between fluctuations of gas velocity and liquid surface waves. Viscosity is determined on base of frequency of gas jet velocity fluctuations when phase-shifting reaches a specified value.
EFFECT: upgraded accuracy of viscosity measurement; simplified design of procedure.
