The extent to which a liquid resists a tendency to flow is defined as
viscosity. In the coatings industry, this behavior is one of the key
Elcometer manufactures and supplies a wide range of viscosity gauges
from flow cups and dip cups to rotational or cone and plate viscometers.
The process of flow through an orifice can often be used as
a relative measurement and classification of viscosity. This measured
kinematic viscosity is generally expressed in seconds of flow time
which can be converted into Centistokes using a viscosity disc
Using the same principle as flow cups, dip cups - Frikmar,
Zahn, Shell, etc. - can be used to provide a quick viscosity
measurement on the shop floor or on site.
Rotational viscometers are used to determine the viscosity
of liquids which do not depend solely on temperature and pressure. The
behavior of non-Newtonian liquids which can be determined using a range
of rotational viscometers in particular the Cone and Plate viscometers.
