Magnetic flowmeters seldomly fail because of no mechanical moving parts. However, flow measurement can sometimes be affected by bubbles, solids or sudden change of conductivity. These process conditions cause fluctuating outputs, resulting in product quality concerns. To maintain reliable flow measurement, the flow-meters must have the performance capability to cope with such disturbances.
ADMAG Total Insight series AXG Magnetic Flowmeter has the unique system “Dual Frequency Excitation”. It is capable of stable flow measurement with high noise immunity. With Flow Noise Diagnosis Function, AXG can detect the following abnormalities.
The graph below shows an example of measurement results. The flow output of AXG is compared with that of other company’s flowmeters with unstable conductivity condition. AXG outputs more stable flow rate than the magnetic flowmeters of Company A and Company B.
In addition, AXG is capable of outputting application noise (purple line). This output can be used for detecting the abnormality of flow before the output becomes unstable.

The magnetic flowmeter is one of the instrumentation devices used for a long time in plants. The magnetic flowmeter is a product that has no mechanical moving parts and is easy to maintain. It is difficult to recognize the abnormality of fluid until output abnormality occurs. AXG can continue providing stable flow measurement even if abnormal fluid condition occurs. In addition to this, AXG can detect abnormalities of the application. It contributes to stable plant operations.
The ADMAG TI series AXG is ideal for industrial process lines like oil & gas/chemical/pulp & paper/food & beverage/metal & mining applications. With outstanding reliability and ease of operation and maintenance, developed on decades of field-proven experience, the AXG will increase user benefits while reducing total cost of ownership.
ADMAG Total Insight is an electromagnetic flowmeter based on the "Total Insight" concept that provides solutions and functions for issues at each stage of the life cycle and contributes to the realization of reduced operating costs.
Yokogawa's experience with magnetic flowmeters spans decades. Our magnetic flow meters provide flexible configurations for industrial use in most areas.
