15.15.4 Activating the compensation for a liquid with a quadratic
viscosity compensation curve
To activate the compensation for a liquid with a quadratic viscosity compensation curve, 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.
→
Quadratic
→
Confirm.
→
Set the value of constant a of the quadratic 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 constant b of the quadratic curve, in the displayed units, and in the scientific
notation.
→
Confirm.
→
Set the value of constant c of the quadratic curve, in the displayed units, and in the scientific
notation.
→
Confirm.
→
Save.
The compensation for a liquid with a quadratic 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 wrong constant values have 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 constant values.
