Viscosity Flow Cup NOVOTEST VZ is designed for rapid determination of the relative viscosity (flow time) of paints and other (Newtonian) liquids. Viscosity cup could be manufactured in compliance with: DIN 53211-87 (DIN 4), UNE ISO DIN 2431, ASTM D 120087 (FORD), ASTM D 4212-93 (ZHAN). Viscosity cup is available in two models: on a tripod – Viscosity Flow Cup NOVOTEST VZ and a submersible type – Viscosity Dip Cup NOVOTEST VZ-P.
Viscosity cup is a reservoir shaped like a funnel with three interchangeable nozzles. The operating principle of the viscometer is based on determining of the time of the expiration of a certain volume of the testing liquid through the nozzle. Viscosity Flow Cup NOVOTEST VZ is produced of stainless steel. Viscosity cup – is one of the fundamental parameters measuring tool for consumables. It is used to control the viscosity of applicable liquids, as varnishes, paints, oils, liquid inks, and others. The conventional viscosity value is determined by the time (in seconds) during which a known volume of fluid flowing through the nozzle of a certain diameter.
The kinematic viscosity is determined by formulas or by tables and graphs out of measured flow time.
Advantages:
- Simplicity of design
- High measuring accuracy
- Variations of orifices sizes according to the standards
