Flow cups are designed to accurately measure the
viscosity
The viscosity of a fluid is a measure of its resistance to deformation at a given rate. For liquids, it corresponds to the informal concept of "thickness": for example, syrup has a higher viscosity than water.

The process of flow through an
orifice can often be used as a relative measurement and classification of viscosity.

Flow cups are manufactured using high grade aluminium alloy with stainless steel orifices (where indicated), flow cups are available with a range of UKAS / ISO 17025 certified standard oils to confirm the flow cup is measuring within specification.
