You calculate viscosity by measuring the amount of time it takes for the liquid to move between two marks. Liquid is drawn by suction into the upper bulb and allowed to flow down into the lower bulb. Glass capillary viscometers or Ostwald or Ubbelohde viscometers consist of a U-shaped glass tube held vertically in a controlled temperature bath.
What Are the Different Types of Viscometers? Viscometers measure using a single flow condition. In general, viscometers move an object through a stationary fluid or move the fluid past a stationary object to measure the friction between the fluid and the object or surface. An example is the slower flow of syrup from a container - syrup is more viscous than water. Viscometers are instruments used to measure viscosity, the internal friction of the layers of a liquid in motion. Viscometers or viscosimeters are important to many industries, including the adhesive, biotech, chemical, food, paint, petroleum, and pharmaceutical industries.
Instruments used to measure the viscosity of a fluid available in a variety of configurations.
