6.5.4 Density calibration (menu C1.2.1)
Mass flowmeters are calibrated for density in the factory. Density calibration is based on 2
calibration points. In the factory, air and water are used under reference conditions. The result
of this calibration is saved in the converter electronics and stored in the factory settings.
Regardless, various applications require maximum accuracy which can only be achieved with
on-site calibration.
Available options:
Example of 1 point calibration with town water
