15.15.3 Activating the compensation for a liquid with a linear viscosity
compensation curve
To activate the compensation for a liquid with a viscosity that changes in a linear way with the liquid tem-
perature, do the following:
→
Go to the
CONFIGURATION
view.
→
SAW sensor
→
Confirm to access the Parameter view.
→
Viscosity compensation
→
Settings The current settings are displayed.
→
Confirm.
→
Linear
→
Confirm.
→
Set the value of the constant a of the linear curve, in the displayed units (mm
2
/s), and in the sci-
entific notation. For example, to set the value 0.03724, enter 3.724000E-02 or, to set the value 372.4,
enter 3.02.
→
Confirm.
→
Set the value of the constant b of the linear curve, in the displayed units, and in the scientific
notation.
→
Confirm.
→
Save.
The compensation for a liquid with a linear compensation curve is active.
If the calculated result of the equation is negative or equal to 0 (for example if the liquid temperature is not
in the range covered by the equation, or if a wrong constant value has been entered), the compensated
volume flow is incorrect and the error message Viscosity compensation failed is displayed. If the message
is displayed, do the following:
→
Make sure the liquid temperature is in the range covered by the equation.
→
Make sure you have entered correct a constant value.
