METHOD DETERMINING VISCOSITY OF LIQUID MEDIA AND GEAR FOR ITS IMPLEMENTATION Russian patent published in 2002 - IPC

FIELD: various branches of industry where control over composition and properties of liquids is vital. SUBSTANCE: method determining viscosity of liquid media consists in action of gas jet on surface deformed by interaction. Liquid is placed in maximum of E-field of resonance oscillation of type E₀₁₀ of cylindrical cavity resonator and gas jet is fed by short pneumatic pulses. Viscosity is evaluated by duration t_tp of transit process of free oscillations of surface of liquid and time t_ss between two stationary states of surface of liquid. Gear for implementation of process has cylindrical cavity resonator, SHF oscillator, jet pipe, intake loop, amplitude detector and float. EFFECT: increased accuracy of measurement of viscosity of liquid. 2 cl, 1 dwg
