Page 13: Set Point Range And Rated Flow Range
PF2M7(-L) Series Set Point Range and Rated Flow Range Set the flow rate within the rated flow range. The set point range is the range of flow rate that can be set in the switch. The rated flow range is the range that satisfies the switch specifications (accuracy, linearity, etc.). It is possible to set a value outside of the rated flow range if it is within the set point range, however, the satisfaction of specifications can not be guaranteed. -
