Viscosity Flow Cup Method

Viscosity cups are however only suitable for lower viscosities and not for highly viscous substances such as pastes etc.

Viscosity flow cup method. Viscosity cups remain the most important quick and simple method to measure the consistency of fluids in the laboratory and in production. The number immediately following the designation indicates the year of original adoption or in the case of revision the year of last revision. A flow cup is a cup of a specified size and volume with an overflow channel at the top and a hole of a defined size in the bottom. The measured kinematic viscosity is generally expressed in seconds s flow time.

However the conditions in a simple flow. A number in parentheses indicates the year of. If the standards stipulate conversion methods the flow time. And they are available in a range of designs in accordance with national and international standards with various orifice diameters to suit different viscosities.

This precision din cup din viscosity flow cup is designed to measure the viscosity of sample liquids e g varnishes paints and related liquids and fluids. Under ideal conditions this rate of flow would be proportional to the kinematic viscosity expressed in stokes and centistokes that is dependent upon the specific gravity of the draining liquid. Viscosity flow cups are very easy to use instruments of anodized aluminum with a stainless steel orifice for measuring the consistency of paints varnishes and similar products. The ford viscosity cup is a simple gravity device that permits the timed flow of a known volume of liquid passing through an orifice located at the bottom.

As a rule the equations for getting viscosity from the flow time are empirically determined for each cup by way of calibration tests with viscosity reference. Viscosity flow cups viscosity flow cups are very easy to use instruments made of anodized aluminium with a stainless steel orifice for measuring the consistency of paints varnishes and similar products. The measured kinematic viscosity is generally expressed in seconds s flow time. To evaluate the viscosity of an experimental sample with this din flow cup the flow time measured in seconds s is converted into centistokes cst presenting the viscosity value.
