The ADMAG AXR two-wire magnetic flow meter can be installed in the two-wire system without any AC power source, thus drastically reducing the initial instrumentation cost. The ADMAG AXR is the world’s first two-wire magnetic flow meter which employs the fluid noise free “Dual Frequency Excitation Method,” achieving excellent stability for instrumentation. Like the AXF four-wire magnetic flow meter series, the ADMAG AXR has user-friendly functions such as a full dot-matrix LCD indicator, electrode adhesion level diagnosis function, and a multi-lingual display. The magnet switches can be used for checking and setting parameters without opening the case cover.


2-wire Power Loop

An extra AC power supply is not necessary. 2-wire loop powered performance allows direct connection to DCS I/O card possible, allowing for real cost reductions.

  • Reduced CAPEX and OPEX on site.
  • Power consumption reduced by 40% compared to a typical 4-wire magnetic flowmeter.
  • Annual CO2 emissions can be reduced from approximately 60 kg to 1.2 kg (compared to a standard 4-wire magnetic flowmeter).

Dual Frequency Performance

Yokogawa’s unique and advanced excitation method, “Dual Frequency Excitation,” achieves stable measurement, zero stability and quick response times. The exclusive technology for stable and reliable measurement on your site.

Noise Reduction Technology

Flow noise reduction is further achieved by incorporating smooth mirror finished PFA liners and special surface finished electrodes. This is further enhanced with aligned super high density coils that generate a stronger magnetic field.

SIL2 Certified

Yokogawa believes safety should not be an option; it should be standard in all modern products. AXR is the first 2-wire magmeter of SIL2 Safety Integrity Level (IEC 61508) certified. AXR is capable of SIL2 single use and SIL3 redundant use, as standard.

Parameter Operation

AXR has magnet switches for parameter setting. Users can access the functions without removing the case cover in hazardous, humid, and dusty environments.

Adhesion Diagnostic Level Function

The electrode is one of the most important parts of a magnetic flow meter. Only ADMAG flow meters have “Adhesion Diagnostic Level Function”. It diagnoses the condition of electrode surface and indicates the adhesion/coating in 4 levels. Users can change the detection level (threshold) depending on each individual process condition. This allows for predictive maintenance and reduced operating costs.

Alarm Indication

ADMAG AXR employs a full-dot matrix LCD indicator. It can display up to 3 lines as required by the user and is available in multiple languages. If an alarm is triggered, a clear message is displayed along with a solution.

High Accuracy

The ADMAG AXR performs 0.5% of rate under normal flow rate conditions.
