| abstract | THE INVENTION CONCERNS MEASUREMENT OF THE KINEMATIC VISCOSITY OF LIQUIDS BY MEANS OF A CAPILLAR BASED ON THE PRINCIPLE OF THE VISCULAR LEVEL OF THE UBELLOW. THE PURPOSE OF THE INVENTION IS TO IMPROVE THE ACCURACY OF MEASUREMENTS OF KINEMATIC VISCOSITY OF NON-NEWTONIAN LIQUIDS AND LIQUID SUBSTANCES NEAR CRYSTALLIZATION TEMPERATURE A CAPILLARY VISCOSETER WITH A WIPE LEVEL IS PERFORMED WITH SEVERAL MEASURING VOLUMES. THE TOP OF THE CAPILLARY TUBE IS CONNECTED WITH THE BOTTOM MEASURING VOLUME WITH THE HELP OF THE S-SHAPED TUBE. DIAMETER S-shaped tube is selected from RATIO √ (2Σ) / (ρG) ≤ D ≤ √ ( 100. RE 2 * 98M 2 D 2) / (εG. Hρ 2).
