Description

Magnetic-inductive flow meter (SM Foodmag 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
Convenient operation via buttons or parameter setting via IO-Link
