Product Overview

AXF125G‑NNAH1N‑BD21‑4NB is DN125 integral‑type magnetic flowmeter of Yokogawa ADMAG AXF series. Designed for large‑diameter conductive liquid flow measurement in water‑supply, wastewater, chemical and power‑plant process pipelines. Dual‑frequency excitation suppresses fluid noise and slurry‑flow disturbance. HART communication supports remote instrument management; local LCD provides instantaneous flow, totalizer and alarm information. Obsolete field device, surplus and refurbished tested spare units for legacy site retrofit and instrument‑replacement workYokogawa E….

Application Notes

‑ Guarantee full‑filled measuring pipe during installation; respect flow‑direction marking. ‑ Isolate instrument wiring from high‑voltage power‑cable routes. ‑ Complete zero‑adjustment before formal operation. ‑ Typical deployment: process‑plant large‑bore magnetic flowmeter spare‑part stocking.
