Viscosity Measurement Flow Cup

The viscosity is established in terms of the time in seconds in which a precisely controlled volume of fluid flows out through a nozzle of the viscosity cup.

Viscosity measurement flow cup.

Whether your spraying wood finishes industrial enamels or anything in between a paint viscosity cup allows you to know just how thin your paint is. Mxbaoheng nk 2 viscosity cup 50ml viscometer flow cup mixing thinning tool 70 370cst for paint industry viscosity measurement 3 0 out of 5 stars 1 31 56 31. The process of flow through an orifice can often be used as a relative measurement and classification of viscosity. However the conditions in a simple flow.

A flow cup is a cup of a specified size and volume with an overflow channel at the top and a hole of a defined size in the bottom. Viscosity cups consist of a hollow cylinder which terminate in a nozzle in the bottom. This measured kinematic viscosity is generally expressed in seconds of flow time which can be converted into centistokes using a viscosity disc calculator. Why get a viscosity cup viscosity cups like ford and zahn cups are handy tools at as a painter.

And they are available in a range of designs in accordance with national and international standards with various orifice diameters to suit different viscosities. Viscosity flow cups are very easy to use instruments of anodized aluminum with a stainless steel orifice for measuring the consistency of paints varnishes and similar products. Different cups have different shapes and hole sizes and because times too short or too long are unsuitable for any given viscosity there is an optimum cup with times. Excess fluid is collected in the gutter channel.

The unit of measurement is centipoise a universally used metric unit of viscosity. For liquids it corresponds to the informal concept of thickness. Additionally knowing the viscosity of your paint allows you to have a reference range so you can select equipment settings that will let you achieve a. Viscosity can be conceptualized as quantifying the internal frictional force that arises between adjacent layers of fluid that are in relative motion.

The measured kinematic viscosity is generally expressed in seconds s flow time. The viscosity of a fluid is a measure of its resistance to deformation at a given rate. Efflux cups flow cups based on different design types zahn shell gardco ez zahn gardco signature zahn and din the unit of measurement is seconds or the time it takes to drain the test cup all cups hold a standard amount of fluid. Many printers coaters measure their viscosity using cups with holes in the bottom by finding how many seconds it takes to empty the full cup or rather for the flow to break.
