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.
