Description

U-Tube Viscometer (Glass Capillary Viscometer)

The U-Tube Viscometer is a type of glass tube widely used for measuring the viscosity of fluids.


Understanding Viscosity

Viscosity, represents the resistance of a fluid to flow.

  • Low viscosity: The fluid flows easily (e.g., water).

  • High viscosity: The fluid resists flow (e.g., honey at room temperature or bitumen at 80–90 °C).

To fully understand viscosity, it’s important to differentiate between Newtonian and non-Newtonian fluids.


Newtonian vs Non-Newtonian Fluids

  • Newtonian fluids: Viscosity is independent of temperature.
    Example: Water has a constant viscosity whether at 10 °C or 80 °C.

  • Non-Newtonian fluids: Viscosity changes with temperature or shear rate.
    Example: Bitumen is nearly solid at 25 °C but becomes much less viscous than water at 135 °C.


U-Tube Viscometer for Viscosity Measurement

By combining these concepts, glass viscometers have been developed to accurately measure viscosity at specific temperatures and conditions.

The U-Tube Viscometer (Reversed Flow U-Tube) is particularly suitable for opaque fluids like bitumen.

  • Primarily used for kinematic viscosity tests at 135 °C.

  • Different tube numbers are selected based on the expected viscosity range of the fluid.

This viscometer allows testers to obtain precise viscosity values, which are crucial for quality control and research in asphalt, petroleum, and chemical industries.

Main Applications of U-Tube Viscometer

  • Measurement of kinematic viscosity of bitumen and opaque petroleum products.

  • Viscosity testing at controlled temperatures (typically 135 °C).

  • Calculation of kinematic viscosity based on the flow time of the fluid.

  • Suitable for opaque liquids up to 300,000 mm²/s (cSt).

  • Used in standard laboratories, quality control labs, and refineries.


Construction and Technical Features

  • Body Material: Heat-resistant borosilicate glass.

  • Designed according to BS U-Tube Modified Reverse Flow model.

  • Suitable for precise viscosity tests in temperature-controlled viscosity baths.
