A DIN flow cup meter is a viscometer to determine the toughness of liquids. It is commonly used in the industrial sector as well as in research laboratories. However, only low-viscosity liquids can be measured by means of this method as liquids cannot pass through the nozzles if their viscosity is too high. Therefore, Newtonian liquids can be tested by the flow cup meter with the highest accuracies. The viscosity is determined on the basis of the flow rate and the time the liquid needs to pass through the nozzle from the flow cup. The start time is when the liquid exits the flow cup at the lower edge of the nozzle. The time is stopped as soon as the liquid does not run smoothly anymore or stops. Additionally, there are immersion cups for quick on-site measurement which are only immersed in the medium to be measured. You can start the time measurement as soon as you lift the cup and the liquid escapes from the nozzle. When you finish your measurement, it is crucial that you clean the flow cup meter as dried-on residues can impair the next measurement result. You should also make sure not to use pointed or sharp tools for cleaning because scratches and abrasion also affect the result.
