  • Clamp-On
    • Flow rate can be measured just by sandwiching the existing tube.
      Essentially clean because it does not contact the piping.
  • Energy saving and space saving
    • Simultaneous measurement of up to 6 lines with one SFC011GS.
      Multiple units can be connected to each other (No need for crossover wiring).
  • High-speed operation
    • 30 ms arithmetic processing.
  • Zero adjustment
    • By performing zero adjustment before measurement, it can be started under the optimum conditions for the fluid to be measured.
  • Abundant functions
    • 7Seg LED (red, 4 digits) indicates instantaneous flow rate and status.
    • Various analog outputs of instantaneous flow rate (select according to output types).
    • Frequency output (1 kHz F.S.), error output, instantaneous flow rate upper/lower limit alarm,
        integrated flow rate output,and integrated flow rate upper limit alarm (open collector).
    • Parameter settings and flow rate data acquisition are available via RS-485 communication.
    • RS-485 communication converter (sold separately) is required.
  • Conformity standards
    • EMC conformity standards: CISPR11:2009+A1:2010 Group1 ClassA, EN61326-2-3:2013
    • RoHS2 compliance
