Yokogawa AXF electromagnetic flowmeter introduction
1: AXF electromagnetic flowmeter adopts dual-frequency excitation. Enhanced dual-frequency excitation is more often used to handle more demanding situations.
The AXF has a number of easy-to-use functions; such as electrode contamination level diagnostics, infrared switches can set parameters without opening the cover, and can change the direction of electrical connections in the field. The AXF fieldbus type electromagnetic flowmeter has specifications based on FOUNDATION™ fieldbus, which enables more flexible instrument configuration through higher-level communication capabilities, and saves cables through multi-point wiring to reduce costs.
2: Since 1953* developing electromagnetic flowmeters for industrial use, Yokogawa has been focusing on expanding the application range of this technology. To ensure a high level of reliability, all critical components are manufactured in-house and strictly controlled according to our quality standards.

| The features for users |
| Diagnosis of fluid stickiness |
| Continuously monitor the amount of insulating material accumulated on the electrodes to determine when maintenance is required. Optional replaceable electrodes are available for easy removal and cleaning. |
| Flexible wiring port orientation |
| The converter and terminal box can be reversed in various orientations to match the wiring location on the installation site. |
| Clear and rich display functions |
| The large full-dot-matrix backlit LCD display can display various information on three lines. When an alarm occurs, a full description of the appropriate countermeasures is displayed. |
| easy setup |
| Commonly used parameters are organized in a collection at the top of the display. The infrared sensor switch is adopted, and parameter setting can be completed without opening the cover. |
| Runs fast after installation |
| The AXF is parameterized at the time of delivery, so it can be put into operation after installation and wiring. |
| Expansion of the product range |
| Improved accuracy specification |
| Standard accuracy is 0.35% of reading. With optional accessories, higher accuracy can be obtained, with a correction accuracy of 0.2% of reading. |
| Min Small diameter flange type |
| A 2.5mm micro-diameter flange type is available. |
| Various hygienic process connections |
| A variety of hygienic process connections are available, including Tri-Clamp, ISO, DIN and SMS. |
| Enhanced performance |
| Enhanced dual frequency excitation |
| Optional enhanced dual-frequency excitation mode. Provides highly stable measurements for high-concentration slurries or low-conductivity fluids. |
| Low conductivity is smaller |
|
The newly designed AXF converter enables the measurement of fluids with conductivity as low as 1 µS/cm. (depending on pipe diameter and fluid conditions) |
| High-speed pulse output |
|
High-speed pulse output of 10,000pps (pulses per second), suitable for short-time batch processing applications. |
