DIN Viscosity Flow Cups

The Elcometer 2350 DIN Viscosity Flow Cups Viscosity Flow Cups are very easy to use instruments made of anodized aluminium with a stainless steel orifice, for measuring the consistency of paints, varnishes and similar products.

The measured kinematic viscosity is generally expressed in seconds(s) flow time. If the Standards stipulate conversion methods the flow time can be converted into Centistokes (cSt) using the Elcometer ElcoCalc™ Mobile Apps.

Calibration certificates which offer traceability and assurance that each viscosity cup has been individually tested and comply to Standards are also available.

The cups can be supplied separately or with an adjustable stand which includes a precision level and an overflow glass draw plate. They can also be supplied with a flow jacket for temperature control (thermojacket).

ElcoCalc™ Mobile App

Fast and easy to use, ElcoCalc™ instantly converts viscosity cup flow time in seconds into Centistokes (cSt).

ElcoCalc™ is free software that is available on Android and the App Store. Compatible with Android™ mobile devices running Android™ 2.1 or later and also iPod, iPhone and iPad running iOS 4.0 or later.

How to measure viscosity using Elcometer Flow Cups

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. And they are available in a range of designs in accordance with National and International Standards, with various orifice diameters to suit different viscosities.
