ADMAG AXF Magnetic Flow Meters

Some specifications of the magnetic flowmeter ADMAG AXF series integral type and remote converter AXFA14G were discontinued on March 29, 2019.
The recommended alternative products are as follows.

 

The ADMAG AXF is the magnetic flow meter which has adopted the proven Dual Frequency Excitation. Moreover, the Enhanced Dual Frequency Excitation has been newly added to tackle more severe applications.

The AXF has user-friendly functions; such as an electrode adhesion level diagnosis function, infra-red switches which can be used for setting parameters without opening the case cover, ability to change the direction of electrical connection on the site.

Based on FOUNDATION™ fieldbus specifications, AXF Fieldbus models offer more flexible instrumentation through a higher level communication capability and propose the cost reduction by multi-drop wirings with less cables. FOUNDATION™ fieldbus is a registered trademark of Fieldbus FOUNDATION.

Note: The "Dual Frequency Excitation Method" is a Yokogawa innovation.

User-oriented Functionality

Fluid Adhesion Level Diagnosis
The amount of insulating material on the electrode is constantly monitored to determine when maintenance should be performed. An optional replaceable electrode is easy to remove and clean.

Flexible Electrical Connection Direction
The converter or the terminal box can be rotated in either direction to match the position of the electrical connections at the installation site.

Clear and Versatile Indications
The large, backlit full dot matrix LCD can display a variety of messages up to three lines in length. When an alarm condition occurs, a full description of the appropriate countermeasure is displayed.

Easy Setup
The most frequently used parameters are arranged in a group at the top of the display. Infrared switches enable the setting of parameters without opening the cover.

Operation Immediately after Installation
The AXF is shipped with the main parameters completely set and can go into operation as soon as installation and wiring are completed.

Expansion of Product Lineup

Improved Accuracy Specification
The standard accuracy is 0.35% of reading. Also available as an option is high accuracy calibration rated at 0.2% of reading.

Extra Small Size Flange Type
Flange types are now available in sizes as small as 2.5 mm.

Variety of Sanitary Connections
A wider variety of sanitary connections are now available, including Tri-Clamp, ISO, DIN and SMS.

Enhanced Performance

Enhanced Dual Frequency Excitation
The enhanced dual frequency excitation method is available as an option. This provides highly stable measurements involving high concentration slurries or low conductivity fluids.

Lower Minimum Conductivity
The newly designed AXF converter permits the measurement of fluids with conductivity as low as 1μS/cm depending on the nominal pipe size and fluid condition.

High-Speed Pulse Output
The maximum rate for high speed applications such as short-duration batch processes is now 10,000 pps (pulses per second).
