Method of measurement
The most accurate method to
determine the viscosity of liquids
is by using viscometers.
The ViscoSystem ® range uses
this method. What is actually
measured is the time a defined
volume of liquid requires to
flow through a capillary tube of
a specific length and width.
Units of the ViscoSystem ® range
can measure flow-through
times with an accuracy of
0.01 %.
In all devices, the liquid meniscus
in the viscometer can be
measured in two different ways:
opto-electronically or using
TC sensors.
Where as the optical system
recognizes the liquid meniscus
using optical fibres, the TC viscometers
utilize the effect of
different thermal conductivity
of air and fluids.
