Series PFMB

A digital flow switch monitors and displays instantaneous and accumulated flow, and transmits output signals when critical set points are detected.  Switch outputs can trigger machine controls to continue or stop operation, indicate an emergency condition, or signal a maintenance requirement.  A comprehensive set of functions is available in a compact, space-saving package.

  • Suitable fluids include air or nitrogen
  • A flow ratio of 100:1 with maximum values of 200, 500, or 1000 L/min
  • 2 switch outputs available, or 1 switch output along with an analog current or voltage output
  • CE, UL/CSA (200L type only), RoHS compliance
  • Optimize response time with 1 of 5 settings from 0.05 to 2.0 seconds
  • Protect settings with key lock and password code security functions
