Yokogawa Introduces The World's First Magnetic Flowmeter with Electrode Coating Diagnostics
NEWNAN, Ga. ¡X Yokogawa introduces the Admag AXF Magnetic Flowmeter as the successor to the very successful Admag AM, AE and SE series.

The AXF series of magnetic flowmeters has been developed based on Yokogawa¡¦s decades long experience in magnetic flowmeters. The AXF series continues the tradition of high quality and reliability that has become synonymous with the Yokogawa name and in addition features an even higher level of performance and increased functionality.

Retaining all the features and functions of the Admag series of flowmeters, in addition the AXF series offers an enhanced dual frequency excitation method as an option for difficult applications as well as new diagnostics to detect electrode coating combined with an optional replaceable electrode design. The user benefits through greater reliability and lower total cost of ownership.

Product Features

ć Diagnostics to detect insulating coatings on the electrodes

By constantly monitoring the change in the impedance of the electrode circuit due to the build-up of insulating coatings, the AXF converter will display 4 different levels of coating and provide an alarm function.

ć Optional replaceable electrodes

Electrode maintenance and cleaning becomes easier because the user can rely on the new predictive diagnostics to monitor the status of the electrodes and then remove them for cleaning if necessary.

ć Improved accuracy specification

The standard performance specification for AXF is 0.35% of reading. Also available is an optional high accuracy calibration rated at 0.2% of reading.

ć Optional enhanced dual frequency excitation method

The user can select a 165 Hz high frequency component for very high concentration slurries to ensure greater stability and quicker response.

ƒá Minimum fluid conductivity of 1 ƒÝS/cm

With the newly designed AXF flow converter, improvements to the input circuit now permit the measurement of fluids with conductivity as low as 1ƒÝS/cm.

ć Three line display with infrared switches

The LCD indicator employs a large, backlit, full dot matrix display. One to three lines are available and these can be programmed to indicate a wide variety of display possibilities, including a bar graph for flow rate indication and a graphical representation of the extent to which the electrodes may be coating. Infrared switches permit programming through the glass without the need to open the enclosure cover.

For more than 40 years, Yokogawa has kept pace with evolving user needs with the continuous introduction of new products to answer modern challenges with the latest technology. Our market leadership of more than 230,000 installed units worldwide proves the confidence our customers have in our magnetic flowmeters.
