Scratches and scrapes in the flow cup also affect the result. It should also be ensured that no pointed or sharp tools are used for cleaning. viscosity, and hiding power test, there several tests can be done also such as wash-ability and. After completion of the measurement, it is imperative that the flow cup is cleaned, as dried-on residues can falsify the next measurement result. Paints Industry: Raw materials & unit operations & Equipment & Manufacturing & Quality tests. As soon as you lift out the cup and the liquid comes out of the nozzle, you can start timing. viscosity meter High performance viscosity sensor High performance viscosity meter kits 7827 Product Data Sheet PS-001217, Rev. In addition, there are immersion cups that are suitable for quick measurements on site these are only immersed in the material to be measured.
It is stopped as soon as the liquid no longer flows evenly or the liquid breaks off. The start time begins when the liquid emerges at the lower edge of the nozzle. Simply dip the cup in the coating and time how long it takes to run out of the cup. Use this viscosity cup to easily measure the thickness of the material you’re using. Achieving the perfect ratio of paint to water/thinner can be difficult. The viscosity can be determined on the basis of the flow volume and the measured time that the liquid needs to run through the nozzle from the flow cup. Paint Consistency Measuring Cup Get the Perfect Ratio. Liquids with Newtonian behavior therefore give the most accurate results in the flow cup. Due to the form of the measuring method, however, the determination is only carried out on low-viscosity liquids, since the liquid cannot run off through the nozzles if the viscosities are too high. The flow cups are often used in industry and research laboratories. Paint viscosity testers are viscosity meters to determine the viscosity of liquids.
