1 OVERVIEW

Elcometer Viscosity Flow Cups are easy-to-use instruments for
measuring the consistency of liquids.
The cup is supported in a stand and is filled with the liquid under test.
The time taken for the liquid to drain through the orifice in the bottom of
the cup is measured.
The measured kinematic viscosity is generally expressed in seconds (s)
flow time, which can be converted to Centistokes (cSt), if stipulated in the
Standard. The Elcometer 2400 Viscosity Conversion Disc , Elcometer
ElcoCalc™ Mobile App (see www.elcometer.com) or the look-up tables in
Appendix 1 (after page jp-7) can be used for this purpose.
A wide range of cups with different orifices is available for
measurements between 5 cSt and 5100 cSt.

3 TEST PROCEDURE

3.1 BEFORE YOU START
1 Select a cup which gives a flow time of between 30 seconds and
100 seconds.
2 Ensure the cup and the orifice are clean and free of debris.
3 The liquid being tested must be homogeneous and must not
contain any bubbles. Use freshly strained samples only.
4 The liquid being tested must be newtonian. To determine
whether a liquid is newtonian, carry out the following
measurements using the instructions given in Section 3.2 'Test
Procedure' on page en-3:
Fill the cup and measure flow time immediately after filling.
Ÿ
Fill the cup, wait one minute, then measure flow time.
Ÿ
If the difference between the two flow times is greater than 10%,
the liquid is considered to be non-newtonian and cannot be tested
using the Viscosity Cup.
5 Measure and record the temperature of the liquid.
