ADMAG AXR Two-wire Magnetic Flowmeter
Yokogawa ADMAG AXR Two-wire Magnetic Flowmeter


The ADMAG AXR two-wire magnetic flowmeter can be installed in the two-wire system without any AC power source, thus drastically reducing the initial instrumentation cost. The ADMAG AXR is the world's first two-wire magnetic flowmeter which employs the fluid noise free "Dual Frequency Excitation Method," achieving excellent stability for instrumentation. Like the AXF four-wire magnetic flowmeter series, the ADMAG AXR has user-friendly functions such as a full dot-matrix LCD indicator, electrode adhesion level diagnosis function, and a multi-lingual display. The magnet switches can be used for checking and setting parameters without opening the case cover.
Note: The "Dual Frequency Excitation Method" is a Yokogawa's innovation.
