Flow Monitor - FWS

Brand: WIKA Alexander Wiegand SE & Co. KG
Request Information
The model FWS flow monitors are used for the display and monitoring of the flow of liquid and gaseous media, e.g. in cooling systems and cooling circuits of welding machinery, laser and piping systems, dosing systems, pumps, compressors, hydraulic systems, high-pressure plants and many more.
Features
  • High switching accuracy and functional safety.
  • Large switching range, low switch hysteresis.
  • Continuous switch point setting by the operator.
  • Viscosity compensated models available.
  • Explosion-protected versions.
