Magnetic flow meters, also known as mag meters, are widely used in a variety of industrial field applications due to their reliable flow rate measurements and features such as low pressure loss and maintenance-free operation.
Yokogawa’s ADMAG series magnetic flow meters are designed with dual frequency excitation to achieve stable measurement, zero stability and quick response times.
Total Insight is a Yokogawa concept for optimizing operations and reducing maintenance costs through every phase of the product lifecycle. The ADMAG TI series consists of the ADMAG AXG and the ADMAG AXW electromagnetic flow meters. The ADMAG AXG is a complete redesign of the ADMAG AXF and will accommodate bore diameters from 2.5 mm up to 500 mm, while the revamped ADMAG AXW will accommodate bore diameters ranging from 25 mm to 1800 mm.
The ADMAG TI series AXG is ideal for industrial applications including oil & gas, chemical, and pulp & paper. With built-in diagnostics and exclusive PFA injection liner, the AXG provides ease of operation while reducing total cost of ownership.
The ADMAG TI series AXW is ideal for general industrial applications including water supply and sewage. Sizes range from 1" to 72" and an assortment of lining materials are available.
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.
ADMAG CA magnetic flow meter is excellent at measurement in ultra-low conductivity fluids down to 0.01 microS/cm, adhesive fluids, or slurry fluids.
The AXF magnetic flow meter is a sophisticated product with outstanding reliability and ease of operation, developed on the basis of decades of field experience.
Remote transmitters (converters) for ADMAG TI provide outstanding reliability and quicker response time.
ADMAG TI AXG flow meters are now available with EtherNet/IP communication, the digital communication based on Ethernet technology, whose signal is internationally standardized by ODVA Inc.
Magnetic flow meters consist of a detector and a converter, with the principle of the detector adopting Faraday's electromagnetic induction law. Faraday's Law states that if conductive fluid flows in a magnetic field, an electromagnetic force is generated in proportion to the fluid's flow velocity. Generally, the inner walls of a detector's measurement tube (metal pipe made of SUS, etc.) are lined with a relatively thick insulating layer to prevent the shorting of the generated electromotive force. This insulating layer is referred to as "lining." There are many kinds of lining materials available that provide corrosion and abrasion resistance to the fluids being measured.
All Yokogawa magnetic flow meters are engineered with dual frequency excitation, an innovative method that superimposes high frequencies on low frequencies, providing the best of AC and pulsed DC excitation. This technology ensures excellent flow noise immunity, fast response times, and excellent stability by utilizing the low frequency spectrum while maintaining high accuracy and high zero stability.

With the high temperatures, pressures, and levels of dissolved organics that are encountered, the ADMAG AXF flow meter design is ideal for use in all phases of the chemical recovery process.
The ADMAG AXR employs the patented “Dual Frequency Excitation Method.” This unique technology combines the best properties of low-frequency excitation to enable a stable measurement and high-frequency excitation to deliver excellent noise immunity. As a result, the AXR can suppress process-generated noise to secure zero stability without sacrificing fast response time. In addition, the AXR achieves the same level of noise immunity as a 4-wire circuit under varying fluid conditions and delivers the performance necessary to meet the requirements for control loop applications.
Yokogawa's ceramic liner can offer the customer superior resistance to thermal shock and the failure that can occur due to liner cracking. This is due to Yokogawa's use of 99.9% pure Al2O3 for the liner.
This paper introduces the ADMAG AXR 2-wire magnetic flomwmeter solution for dust collection water application of steel converter.
The slurry measurement is one of the most challenging application for magmeter. In this paper, Yokogawa's solution and expected benefit in aluminum slurry applications will be introduced. ADMAG magnetic flow meter series delivers fit-for-purpose solutions for the difficult applications in mining industry.
The pulp and paper industry has very aggressive and challenging applications for magmeters. There are corrosive Zone chemicals, high temperatures and pressures, and abrasive slurries. Yokogawa can provide the most reliable and accurate meters for each application.
The new digester magmeter enabled accurate and stable flow measurement of the black liquor circulation line, helping the user to stabilize the cooking degree that determines the quality of the chip digesting process.
Continuous technology improvement is ongoing in the pulp & paper industry to obtain the best possible performance. The improved plant performance translates to the higher quality improvement and lower cost, and simultaneously environmental friendly plant operation.
The use of recycled oil as an energy source presents a significant processing problem. ADMAG CA has been shown to provide reliable and stable flow measurement of recycled oil containing water.
More than half a century has passed since Yokogawa developed Japan's first magnetic flow meter for industrial use in 1955, and today, Yokogawa's magnetic flow meters are widely used in a variety of applications thanks to features such as low pressure loss and maintenance-free operation due to no obstacles and moving parts in the fluid flowing pipeline.
After having undergone several improvements, magnetic flow meters have become highly accurate and reliable and are widely used in the industrial instrument field today. Magnetic flow meters consist of a detector and a converter, with the principle of the detector adopting Faraday's electromagnetic induction law.
In 1988, Yokogawa launched the ADMAG series of magnetic flow meters with increased resistance to fluid noise and zero stability, employing dual frequency excitation which was developed based on its long-cultivated technology for flow measurement. Since then, the ADMAG family has augmented its application range with such models as explosion-proof and integral types, and a capacitance type.
