3.5 Directions of measuring accuracy

Due to its construction the flow meter counts the volume of the liquid flowing through being calibrated for use with
AdBlue. The highest measuring accuracy will be reached with a constant flow rate.

3.6 Calibration

To improve the accuracy, the flow meter can be adjusted to the respective applications by calibration.
The calibration factor is either changed directly (from serial no. 023-0000 2000) or the flow meter calculates the
accurate correction factor after a comparative measurement between the displayed and the actual filled volume.
