Magnetic Flowmeters

History of YOKOGAWA's Magnetic Flowmeters

YOKOGAWA's magnetic flowmeter is supported by a long history of more than half a century. We added innovative specifications in each era, and have always lead the industry. The consistent policy of YOKOGAWA's magnetic flowmeter is to have high performance and high quality.

The world's first dual frequency excitation method adopted in the ADMAG AM series announced in 1988 pushed the stability measurement of the magnetic flowmeter to a higher standard. Capacitance type magnetic flowmeter ADMAG CA series has made it possible to measure low conductivity fluid and insulating adhesive fluid. ADMAG AXR series realized overwhelming high performance with limited power supply voltage of two-wires.

And now, it is the birth of ADMAG TI series to adopt the "Total Insight" concept and totally support the product life cycle.

  • ADMAG CA can measure the flow rate of highly concentrated slurry fluid, insulator adhesive fluid and low conductivity fluid.
    • There is no electrical noise since the slurry does not collide with the electrode.
    • The non-wetted electrode type ensures stable flow measurement even if deposits form on the measurement tube.
    • The flow rate can be measured from conductivity 0.01 µS/cm.

  • ADMAG AXR helps reduce wiring costs and power consumption.
    • The two-wire system eliminates the need for power supply wiring. Supply drive power through signal wiring.
    • Low power consumption that is difficult with 4-wire system is realized.
    • Low noise performance is realized.
