Activating the compensation for a liquid with an inverse
quadratic viscosity compensation curve
To activate the compensation for a liquid with an inverse quadratic compensation curve, do the following:
→
Select the device in the navigation area.
→
SAW sensor
→
Parameter
→
Viscosity compensation
→
Settings
The current settings are displayed.
→
Select
Inverse quadratic
→
Set the value of constant
a
of the quadratic curve, in the displayed units (mm
2
/s), and in the scientific
notation. For example, to set the value 0,03724, enter 3.724000E-02 or, to set the value 372,4, enter
3.02.
→
Set the value of constant
b
of the quadratic curve, in the displayed units, and in the scientific notation.
→
Set the value of constant
c
of the quadratic curve, in the displayed units, and in the scientific notation.
The new settings are displayed.
→
Finish
The compensation for a liquid with an inverse quadratic compensation curve is active.
If the calculated result of the equation is negative or equal to 0 (for example if the fluid 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 fluid temperature is in the range covered by the equation.
→
Make sure you have entered correct constant values.
