... The rated flow rate range is the range of flow rate that satisfies the specifications (accuracy, linearity, etc.) of the sensor. Although it is possible to set a value outside the rated flow rate range, the specifications will not be guaranteed even if the value stays within the regulating flow rate range. ...
