The AX FA14 electromagnetic flow converter in the AX F series is a user-friendly product that incorporates advanced features such as electrode adhesion diagnosis and a versatile display. It adopts a dual-frequency excitation method inherited from the ADMAG series, which provides high stability and fast response in flow measurement. Furthermore, an optional extended dual-frequency excitation method is available for more demanding applications.
This manual describes the AXFA14 series electromagnetic flowmeter converter developed by Yokogawa. It highlights user‑friendly features such as a full‑dot matrix LCD, infrared switches, and Easy Setup parameters, as well as diagnostic functions for electrode fouling and optional extended two‑frequency excitation.
The document includes detailed specifications, wiring diagrams, mounting options, safety and explosion‑proof requirements, and optional accessories. It also outlines parameter settings, communication options (BRAIN, HART, fieldbus), and calibration procedures. This manual is written in Japanese.
