AF-E 400 Magmeter for Chemical Dosing

The AF-E 400 is an electromagnetic flow meter for utility applications such as flow monitoring in sludge treatment processes. This ultra-compact magmeter is the ideal choice for applications with conductive liquids in tight spaces such as on chemical dosing skids. It features best-in-class accuracy in every flow range, thus allowing optimal processing in automation. The round bore reduction of the sensor makes this flow meter more resilient in terms of increased pressure, while 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 magmeter can install in extreme proximity to one another (as close as 2 mm / 0.08″). Thus, it can mount in parallel without interference. Furthermore, this electromagnetic flow meter 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. IO-Link also enables faster sensor installation or replacement.
