Viscosity cup uses simple gravity technique to pass known volume of liquid passing through an orifice located at the bottom, The rate of flow would be proportional to the kinematic viscosity. Various viscosity cups are available according to DIN, ISO, Zahn, AFNOR, and ASTM in accordance to ISO 2431, NF T30-014, ASTM D1200 standards.
Flow cups are manufactured with aluminium alloy with stainless steel orifice. Flow cups measures accurately viscosity of liquid paint, ink, varnish and similar products.
