METHOD FR MEASUREMENT OF VISCOSITY

摘要

Method for measurement of viscosity at which one performs immersion of sensitive element arranged as indicator of viscosity, to medium under investigation with excitation of vibrations of indicator of viscosity with following measurement of amplitude of vibrations of indicator of viscosity. One increases pressure of medium under investigation, at pressure coming to given value determined by technical characteristics of device one changes temperature of medium under investigation to standard temperature. At medium under investigation having come to standard temperature 20 °C one excites vibrations of probe with natural frequency. Value of viscosity of medium under investigation is determined by parameters of change of amplitude and frequency of natural vibrations.
