ADMAG AXR Magnetic Flow Meter
Brand: Yokogawa Electric Corporation
The ADMAG AXR two-wire loop-powered magnetic flow meter can be installed in a two-wire system.
The maximum power consumption of the AXR is 0.3W, 40 times less power draw than a traditional magnetic flow meter, resulting in CAPEX and OPEX savings.
The ADMAG AXR is the world's first two-wire magnetic flow meter which employs the fluid noise-free "Dual Frequency Excitation Method," a Yokogawa innovation, achieving excellent stability for instrumentation.
Features- 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.
