1) This maximum pipe diameter specification is only valid when installing the sensor unit centrically in the pipe.
For larger diameters or angular ducts a non-centric sensor position is taken into account for calibration.
IMPORTANT (NOTE)
Deviations from the stated dimension and position tolerances cause additional measuring
uncertainty.
