IFM SMF520 - Magnetic-inductive flow meter SMG65KGFFRKG/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
