Electromagnetic Flow meter AF-E 400

The AF-E 400 is an electromagnetic flowmeter for utility applications and industrial automation. This ultra-compact mag meter is the ideal choice for applications with conductive liquids in tight spaces, e.g. in cooling lines of welding equipment, bending machines and robots or on chemical dosing skids. It features best-in-class accuracy in every flow range, allowing optimal processing in automation. The round bore reduction of the sensor makes the flowmeter more resilient in terms of increased pressure, ensuring high accuracy over a wide pressure and temperature range. Its integrated temperature measurement eliminates the need for an additional sensor.


The AF-E 400 guarantees maximum flexibility when it comes to installation. Due to the special design of its magnetic circuit, field strength and electronics, this mag meter can be positioned in extreme proximity to one another (as close as 2 mm / 0.08″). It can thus be mounted in parallel without interference. The electromagnetic flowmeter offers various output and communication options. Among others, the device features an IO-Link and a Modbus option to provide operators with multiple sensor and application data for smarter factory automation. IO-Link also enables faster sensor installation or replacement.
