Do you face challenges measuring flows that are corrosive, abrasive, or have low conductivity? Are slurry noise and electrode coating compromising your data? For over half a century, Yokogawa's magnetic flowmeters have set the industry standard by consistently introducing innovative specifications. From the world's first dual-frequency excitation method to capacitance-based sensing and the new "Total Insight" concept, Yokogawa delivers high-performance, high-quality flow measurement solutions for the most demanding applications in chemical, pulp & paper, water, and other industries.

Why Choose Yokogawa Magnetic Flowmeters? Solving Slurry Noise, Low Conductivity & Maintenance Challenges

Gain reliable flow data with intelligent features that directly address common industrial pain points.

• Conquer Slurry Noise and Unstable Flow: Traditional magmeters struggle with the electrical noise generated by high-concentration slurries or fluids with solid particles. Yokogawa's dual-frequency excitation method, first introduced in the ADMAG AM series and refined in models like the ADMAG AXR, provides exceptional stability and accuracy by switching between low and high-frequency excitation. This ensures reliable measurement even under challenging flow conditions where slurry noise would cause other meters to fail.

• Measure Previously "Impossible" Fluids: Adhesive fluids and those with very low conductivity (down to 0.01 µS/cm) can render conventional wetted-electrode meters useless due to coating or insufficient signal. The ADMAG CA Series solves this with a capacitance-type (non-wetted electrode) design. This innovative magnetic flowmeter measures flow without the electrodes contacting the fluid, ensuring stable, accurate readings for insulator-adhesive fluids, high-concentration slurries, and even recycled oil containing water, as highlighted in their application notes.

• Gain Total Insight with Advanced Diagnostics: Don't just measure flow; understand the health of your process and instrument. The latest ADMAG Total Insight series (AXG/AXW) is built around a concept of supporting the entire product lifecycle. It features abundant diagnostic functions, including flow noise diagnosis, low conductivity detection, electrode insulation deterioration monitoring, and electrode adhesion detection. These tools enable predictive maintenance, prevent unplanned downtime, and ensure long-term measurement reliability.

• High Accuracy Across a Wide Range: Achieve the precision you need for control and custody transfer. The ADMAG Total Insight series delivers a standard specification accuracy of ±0.3% of reading (ADMAG AXG) , while the ADMAG AXW offers ±0.35% for larger line sizes up to 1800 mm. The specialized CA Series provides reliable measurement with ±0.5% accuracy.
