To calculate an output current into the “original” flow value as the system is measuring it
(without adjusted calibration factor), use the following equation:

Please note: the conversion factor is a fixed value based on the maximum flow range of a
sensor when the calibration factor is set to 1.50. It is not dependant on the actual chosen
calibration factor.
