KINEMATIC VISCOSITY OF ANTIFROGEN L
INSTRUCTIONS FOR USE OF THE
CORRECTION CURVES
Anti-icers and corrosion inhibitors
are inhibitors based on propylene
glycol which are mixed with water.
This prevents undesirable reactions
such as corrosion or the freezing of
hydraulic systems.
These mixtures give rise to other
physical material values than those
occurring in the case of pure water.
These material values depend on the
one hand on the mixture ratio in %,
and on the other on the temperature
of the mixture.
The mixture ratio depends on the
desired properties, for example
frostproofness.

FLOW
As a result of the changed material
values, the flow indicated on the
TacoSetter varies. The reason for this
is the higher viscosity and density
of the water mixture compared with
pure water.
The kinematic viscosity of the water
mixture is the critical factor in determining the correction value. This
value is derived from diagrams and
product documentation published by
the manufacturers of inhibitors. The
diagram set out in Fig. 1, which was
provided by Messrs. Clariant, is the
basis for the specimen calculation
with Antifrogen L.

GLYCOL CORRECTION CURVES
KINEMATIC VISCOSITY OF THE CORRECTION CURVES
CORRECTION CURVES
A separate diagram with nine correction
curves exists for TacoSetter up to DN25
and its flow ranges.
These correction curves cover a
kinematic viscosity range from
1 mm ²/s to 53 mm²/s.
These curves are assigned to the
kinematic viscosity read from Figure 1
in the adjacent table.

Solution
On the basis of the manufacturer’s
diagram Fig 1, a kinematic viscosity
of 7 mm 2/s is arrived at
According to table Fig. 2, 6.7 mm 2/s
indicates correction curve No. 4
An effective flow of 2.6 l/min can
be determined from the indicated
3.5 l/min, using the diagram for
this TacoSetter Inline 100 and curve
No. 4
■■
■■
Conclusion
Given an Antifrogen L concentration
of 38% and a mix temperature of
10 °C, the effective flow diverges
from the indicated flow by -26%.
