The Yokogawa AXFA41C-D1-21/CH paired with the AXFC-4-20 converter represents a four-wire, remote-mounted (split-type) electromagnetic flowmeter system. This configuration is designed for applications where the sensor must be installed in a harsh or inaccessible location (e.g., underground, in a hot area, or on a large pipe), while the converter is mounted remotely in a safe, convenient location like a control panel or cabinet for easy operator access.
