PF3A7*H-L, Modular Digital Flow Switch with IO-Link

PF3A7*H digital flow sensors with modular connection provides simple integration with SMC's AC30 and AC40 series air preparation units.  The flow sensor provides instantaneous flow data as well as cumulative air consumption values.  The -L models include IO-Link and digital outputs with optional analog outputs.

  • Rated flow range: PF3A701H: 10 TO 1000 lpm; PF3A702H: 20 to 2000 lpm
  • Large 2 screen, 3 color display to show both instantaneous and cumulative flow or set value at the same time
  • Can be converted to threaded model using modular connectors and piping adapters 
  • Accuracy: +/-3.0% F.S.
