Rotating bobs are more common, rotating cups reduce the likelihood of vortex formation, and 'cone and plate' viscometers create a constant shear rate at any speed. Rotational viscometers use the concept of torque to measure the effort required to turn a disk or bob in a fluid.This can be done electronically for opaque fluids. Falling ball viscometers measure the time it takes for a sphere of a known size and density to descend through a stationary liquid.

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. In addition, the brookfield viscometer can also connect with PC via RS232. The test data can show on the screen real time and also output by printer.

Glass capillary viscometers or Ostwald or Ubbelohde viscometers consist of a U-shaped glass tube held vertically in a controlled temperature bath. Display selection of white backlight, high brightness LCD display, can directly display the viscosity of the sample, the number of the rotor, speed and other information, data display clear.

Viscometers measure using a single flow condition. The Visgage is used by companies around the world to verify oil viscosity and perform. D4402 Standard Test Method for Viscosity Determinations of Asphalts Using a Rotational Viscometer. D4280 Standard Specification for Extended Life Type, Raised, Retroreflective Pavement Markers.

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. D4212 Standard Test Method for Viscosity by Dip- Type Viscosity Cups. An example is the slower flow of syrup from a container - syrup is more viscous than water. From viscosity testing to flash point testing, we have everything you need to. Viscometers are instruments used to measure viscosity, the internal friction of the layers of a liquid in motion. Discover the wide range of testing Instrument available at CANNON Instrument. 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.
