15.12.10 Setting the temperature compensation to measure the
differentiation factor
All equations used in order to get liquid concentration values are using the default DF temperature
compensation. When changing the DF temperature compensation, you may alter the liquid concen-
tration measurement.
In order that the DF of the liquid stays constant whatever the liquid temperature, the DF must be temper-
ature compensated.
→
You can only set the temperature compensation for 1 of the liquids that may flow through the pipe.
The device has 2 types of temperature compensations to measure the DF:
•
according to an equation that is specific to water, i.e. when water flows through the pipe, the DF will
always be equal to 1, whatever the water temperature. The equation for water cannot be changed. See
chapter 15.12.12 Activating the temperature compensation for water .
• according to an equation of 5th order for which you can set the 5 constants. See chapter 15.12.11 Setting
the temperature compensation for a liquid other than water.
By default, the temperature compensation is made according to an equation that is specific to water and
that cannot be changed.
15.12.11 Setting the temperature compensation for a liquid other than
water
You can set the 5 constants (a
0
...a

) of the equation which compensates the temperature of the liquid to
calculate the DF:
