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 is the world's first 2-wire magnetic flow meter which employs the unique "Dual Frequency Excitation Method," achieving 0.5% of rate of best-in-class accuracy and excellent stability for process measurement. In addition, the newly developed AXR key technologies," achieves the same level of noise immunity as 4-wire type under the fluid condition change and delivers enough performance to meet the requirement to apply in the control loop.
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.
Recently, air pollution legislations such as the Clean Air Act to reduce the amount of air pollution are increasing worldwide. The Clean Air Act address numerous air quality problems. One of these problems is acid rain caused by sulfur dioxide and nitrogen oxide emissions from fossil-fueled power plants and other industrial and transportation sources.
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.
Yokogawa's unique simultaneous dual-frequency excitation method and optional enhanced dual frequency excitation method can offer benefits in this application which can result in tighter control, faster response, more end product per batch, greater profit and a direct cost savings to the customer.
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.

Enabling the operational benefits of two-wire magnetic flow meters while maintaining the performance levels associated with traditional four-wire devices.
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.
