How to measure viscosity using Elcometer Flow Cups

There are a number of ways to measure the viscosity of a liquid, one of which is flow cups - also known as a viscosity cup.
This video will show you how to use a viscosity cup - specifically a viscosity flow cup.
Viscosity cups are available in a range of designs in accordance with National and International Standards, with various orifice diameters to suit different viscosities.
It is a common misconception that the viscosity of a liquid is a measure of how thick or thin it is. When measuring viscosity, what you are actually measuring is the resistance a fluid has to flow.
To test using a viscosity cup, you will need a flow cup, a flow cup stand, a glass plate and bubble level, a stopwatch, a thermometer with a liquid probe, and a container of your sample liquid - ensuring there is enough of a sample to more than fill the flow cup.
If a preferred flow cup isn’t listed on the technical data sheet of the liquid you are testing, then typically you should select a cup that will give an estimated flow time of between 30 and 100 seconds.
However this is dependent on the range of the flow cup you are testing with, or the test method or standard you are working to.
The measured kinematic viscosity is expressed in seconds, which can be converted into Centistokes using either a lookup table; available in the instruction book of your flow cup, or from the Elcometer website; or use the Elcometer 2400 Viscosity Disc.
Alternatively you could use ElcoCalc, Elcometer’s free app available from the Android or Apple App stores. Find out more here: www.elcometer.c...
It’s important to note, not all flow cups produce results that can be converted into Centistokes - in these cases the kinematic viscosity is recorded in seconds flow time.

what is the conversion factor to be used while using AFNOR CUP No 2 , 4 & 6 from time to centistokes?

[@ElcometerOfficialChannel]

Thank you for your question.
The AFNOR Cup is used in accordance with the relevant AFNOR standard, which does not provide a formula for converting time into centistokes. This means results from an AFNOR Cup are typically recorded in seconds flow time, and are used comparatively.

Thanking you for the prompt reply on my request

[@ramalingaml3797]

Your showing sheet to calculate viscosity from flow time .any formulae is there ??

[@ElcometerOfficialChannel]

Thank you for your comment.
When there is a formula available for the Flow Cup you are using, then it will be listed in the relevant Standard. Alternatively you can use an Elcometer 2400 Viscosity Disc, or the free ElcoCalc app for Android and Apple mobile devices to convert the seconds flow time into Centistokes.
Please note, not all cups have conversion formulae.

Hello! Can I ask you a question? What type of oil do you use to calibration?

[@ElcometerOfficialChannel]

Hi,
We specifically use a flow cup viscosity oil supplied by Cannon instruments. The specific kind of oil depends on the standards you are working toward.
For further questions, please get in touch at [e-mail]

what about din cup 6 conversion table?

[@ElcometerOfficialChannel]

Thank you for your comment.
The DIN 4 cup is the only cup in the standard DIN 53211 with a conversion formula. With DIN 6, you can alternatively measure viscosity using the time.

which cup size we use for HST oil his viscosty is 5 centistoke. pl

[@ElcometerOfficialChannel]

Hi, for HST oil you may want to consider using a shell dip cup or zahn dip cup with a very small orifice.
