Product Overview

AXF040G‑NNAH1N‑BD41‑4NB is DN40 ADMAG AXF integral magnetic flowmeter from Yokogawa. It adopts dual‑frequency excitation technology for stable volumetric flow measurement of conductive liquids in chemical, water‑treatment, oil‑gas and energy‑generation plantsYokogawa E…. Supports HART digital communication for remote configuration, diagnostic read‑back and parameter modification. Built‑in multi‑language local LCD enables on‑site flow value observation and alarm indication. Discontinued field instrument, refurbished and surplus tested units available for legacy plant maintenance and replacement projectsYokogawa E….

Application Notes

‑ Install with full pipe condition; avoid air pockets inside measuring tube. ‑ Use shielded cable for signal wiring, separate from high‑power cables. ‑ Perform zero‑point calibration after commissioning. ‑ Typical deployment: process‑plant magnetic flowmeter spare‑part stocking.
