Magnetic-inductive flow meter

SMF621

SMG80KGFFRKG/USD

  • Magnetic-inductive flow meter (SMF series) for the food and beverage industry
  • Measured variables: flow rate, total volume, temperature, conductivity and fluid detection
  • Easy to set up thanks to app-based menu, guided installation and hygienic pushbuttons
  • Reduced cabling by combining supply voltage and output signals via an M12 connection
  • Housing design increases shock and vibration resistance
