|Flow Switches

For PF□ series digital flow switches, what is the relationship between the analog output and the flow rate range?

As it varies depending on the PF□ series, refer to the “Flow rate/Analog output” graphs of each series.
For example, for analog output 1 to 5 VDC types, the flow rate at 1 V may be 0 or it may be the min. rated flow rate.
In addition, for some models, the flow rate at 5 V may be the max. rated flow rate or it may be possible to change the flow rate.
Note) For PF2A series flow switches, the flow rate at 1 V/4 mA is the min. rated flow rate. For other types, the flow rate at 1 V/4 mA is 0.
