AF-E 400

Ultra-compact electromagnetic flowmeter for conductive liquids in tight-space utility and automation applications.

The AF-E 400 is an ultra-compact electromagnetic flowmeter built for measuring conductive liquids such as coolants, process water and chemicals in space-constrained installations. Its round-bore sensor design delivers high accuracy across a wide pressure and temperature range while minimizing pressure loss, and an integrated temperature sensor removes the need for a separate device. With flexible thread connections and multiple output options including 4…20 mA, pulse, frequency, Modbus RTU and IO-Link, it fits seamlessly into modern automation and utility monitoring systems.
