The magneto-inductive flow sensor SMF320 is designed for the precise measurement of volumetric flow rates of conductive liquids in industrial applications. It enables reliable process monitoring and offers extended functionalities.

Extended functions:
Measured variables: In addition to the current flow rate, the sensor detects total volume, flow direction, and the presence of the medium (empty pipe detection). Furthermore, conductivity and temperature data are transmitted via IO-Link to the control and IT systems.

IO-Link communication: Digital data transmission via IO-Link enables seamless integration into existing automation systems and increases transparency in the production process.

Technical features:

- Measurement principle: Magneto-inductive, suitable for conductive media from 20 µS/cm.
- Measuring range: Depends on pipe size, suitable for various flow rates.
- Output signals: Analog output (4...20 mA), switching output, and IO-Link for digital communication.
- Process temperature: Suitable for temperatures up to 90 °C.
- Pressure range: Up to 16 bar, depending on the housing variant.
- Materials: Stainless steel housing; wetted parts suitable for hygienic applications.

Application areas:
The SMF320 is versatile and can be used in:
- Cooling and lubrication circuits
- Water treatment plants
- Processes in the food and beverage industry
By capturing additional parameters such as conductivity and temperature, the need for separate measuring points can be reduced, increasing system efficiency.
