Capillary-Type Viscosity Meter

The capillary viscometer operates based on the principle that the flow of fluid through a fine tube is influenced by viscous resistance, measuring the time required for a fixed volume of liquid to pass through the capillary. The dynamic viscosity is calculated using the Hagen-Poiseuille law, and it is applied for quality control and production process monitoring of Newtonian fluids such as paints and inks.
Selection
When selecting, consider matching the viscosity range of the fluid being measured with the capillary inner diameter—choose a thicker tube for high viscosity. Confirm whether the fluid is Newtonian. Pay attention to the temperature control accuracy. Choose between Ubbelohde or Ostwald structures based on the sample volume. Verify the timing accuracy and the corrosion resistance of the capillary material.
