Linear Compensation - Burkert 8223 Manuel Utilisateur

3.4.2 Linear compensation

If no specific compensation curve corresponds to your process, use one of the 9 linear
compensation factors by using SW2.
If you do not know the compensation factor (average
mine it by doing the following:
1) Measure the conductivity of the fluid at 25 °C (
2) Measure the conductivity of the fluid at a temperature T (
3) Apply the following formula to determine the
