Caution
Set Flow Rate Range and Rated Flow Range
Set the flow rate within the rated flow range.
The set flow rate range is the range of flow rate that can be set on the controller.
The rated flow range is the range that satisfies the sensor’s specifications (accuracy, linearity etc.).
It is possible to set a value outside of the rated flow range, however, the specification is not be guaranteed.
