IN Brief:
- ifm has launched SM Foodmag for food and beverage duty cycles.
- The unit combines flow measurement with medium detection, conductivity, and temperature.
- IO-Link connectivity and onboard diagnostics target faster setup and fault finding.
ifm has launched its SM Foodmag magnetic-inductive flow meter, targeting food and beverage producers that need repeatable flow measurement under strict hygiene constraints, high temperature variability, and frequent cleaning cycles.
According to ifm, the sensor’s value around reliability under harsh operating conditions, and around delivering more usable information to operators and control systems than conventional flow instruments typically expose at the point of use.
At the core is a combined measurement and communications package. ifm says the SM Foodmag detects flow rate, total volume, flow direction, and the presence of the medium — often described as empty-pipe detection — while also transmitting conductivity and temperature via IO-Link to control and IT levels. For processors, that mix of primary and secondary variables can be used both for process control and for monitoring drift: conductivity and temperature trends can help operators interpret product variation, water transitions, or cleaning phases without treating the flow meter as a single-purpose device.
The user interface is designed to be practical on a line. The SM Foodmag includes a fully graphic 3.5-inch display and a 360° status LED, with up to four process values viewable simultaneously. ifm also says operating instructions, the data sheet, and a factory certificate can be accessed via a QR code on the device, and that the installation guide and app-based menu structure are intended to speed initial configuration and access to historical data.
Hardware choices are also aimed at routine food-plant realities: ifm highlights a single-cable approach combining power supply and outputs, using an M12 connection mounted on the back of the unit, and a pre-wired connector concept intended to reduce wiring errors and the opportunity for moisture ingress. The company also points to a compact housing and weight-reduced electronics as a route to improved vibration and shock resistance, and to capacitive pushbuttons designed to work in wet environments and when operated with gloves.
On diagnostics, ifm says the sensor stores up to 200 results, with the last 20 events viewable on the display, and that saved events can also be viewed via its moneo environment. In practice, that shifts some troubleshooting from “meter says 4–20 mA is out of range” into more specific event and status information, which can reduce the time spent isolating whether a deviation is sensor-related, wiring-related, or process-driven.
For food and beverage manufacturers under pressure to run tighter, cleaner, and more automated operations, SM Foodmag sits in the overlap between hygienic instrumentation and data-driven maintenance: fewer compromises on installation, more visibility at the point of measurement, and a more structured hand-off of information into IO-Link infrastructure.
