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.

3.1 BEFORE YOU START

1 Select a cup which gives a flow time of between 30 seconds and

100 seconds.

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:

Ÿ Fill the cup and measure flow time immediately after filling.

Ÿ Fill the cup, wait one minute, then measure flow time.

2 Ensure the cup and the orifice are clean and free of debris.

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.

3 TEST PROCEDURE

2 Allow the temperature of the cup and the

sample to stabilise at the agreed

temperature. Check the temperature of the

sample before filling .

1 Place the cup into the stand and level the

cup using the glass plate and bubble level

supplied with the stand (Figure 1).

3.2 TEST PROCEDURE

3 Place a finger over the cup orifice to close

the orifice (Figure 2).

4 Pour the liquid gently into the cup,

avoiding the formation of air bubbles

(Figure 2).

5 Slide the glass plate over the rim of the

cup to remove excess sample. Avoid the

formation of air bubbles between the glass

plate and the liquid (Figure 3).

6 Remove your finger from cup orifice and

wait for a few minutes to allow any air

bubbles to rise to the top of the liquid.

9 Repeat the test.

10 If the test results do not differ by more than

5%, calculate the average of the two test

results and record the result.

7 Remove the glass plate and start the

stopwatch (Figure 4).

8 Watch the flow of liquid from the orifice and

stop the stopwatch the moment the flow

breaks for the very first time (Figure 5).

c If the test environment is not temperature stabilised a double-walled thermojacket can be used, see

Section 5 ‘ Spares & Accessories’ on page en-5.

DO NOT use wire brushes, metal scrapers, metal files or

other metallic tools for cleaning.

3.3 AFTER TEST

After cleaning, ensure that all materials are removed and that the

instrument is dry.

Clean the viscosity cup and all the equipment used using a suitable

solvent.

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.

4 CARE & MAINTENANCE

Ÿ To check for wear, use Elcometer 2410 Viscosity Cup Standard

Calibration Oils in place of your liquid and measure the flow

time. If wear is detected, contact Elcometer or your local

Elcometer supplier.

Elcometer Viscosity Flow Cups are designed to give many years

reliable service under normal operating conditions.

Ÿ Regularly inspect the cup for damage to the orifice, scratches on

the internal surface or deformation as such flaws will affect the

readings and the cup may have to be replaced.

Ÿ Regular calibration checks over the life of the cup are a

requirement of quality management procedures e.g. ISO 9000

and other standards.

5.4 ELCOMETER 2410 VISCOSITY CUP STANDARD

CALIBRATION OILS

Specific calibration oils can only be used with specific flow cups - refer

to the table below to determine which calibration oil is required for

each cup.

Supplied in ½ litre (1 pint) bottles complete with

calibration certificate, standard oils have a

specific drain time, dependent upon the

viscosity cup type (Ford, DIN, ISO etc.) and the

orifice size or cup number used.

In order to check the viscosity cup’s calibration

or to certify it for ISO purposes, it is imperative

that viscosity cup standard calibration oils are

used.
