The ADMAG CA magnetic flow meter adopts a system to pick up the electromotive force generated in a fluid by electrodes provided outside a ceramic pipe through the capacitance of the pipe. In addition, the flow meter employs a prominent high-frequency excitation method that reduces flow noise in low conductivity fluid.
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. Since ADMAG CA employs a non-wetted electrode construction, picking up the signal voltage by electrode plates provided outside a ceramic pipe through the capacitance of the pipe.
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.
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.
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.
The pulp and paper industry holds some of the most aggressive and challenging applications for magmeters. There are corrosive chemicals, high temperatures and pressures, and abrasive slurries. One application which is particularly difficult is the measurement of pulp stock from the digester to the blow tank. Yokogawa can provide one of the most reliable and accurate meters for this application.
