AXFA11G Magnetic Flow Converter

Brand: Yokogawa Electric Corporation

The AXFA11 magnetic converter retains all the features and functions of the ADMAG series of converters, featuring Yokogawa’s enhanced dual frequency excitation method as an option for difficult applications as well as new diagnostics to detect electrode coating. 

Combined with a flow tube utilizing the optional replaceable electrode design, the user can schedule maintenance for reduced process downtime and in turn a lower total cost of ownership.

The AXFA11 can be combined with AXG and AXW flow meters for specific specifications. 

Its wall-mounted design for general purpose applications can also be used as a universal converter for third-party flow tubes.
