The AXF magnetic flow meter measures fluid flow by sensing the variations in conductivity that occur as fluid passes through a magnetic field at different rates. The instrument features an adhesion-level diagnostic function and replaceable electrodes that are easy to maintain. It is designed to be inviting to the touch and has carefully positioned, ribbed patterns for easy handling. Its deep green color communicates an impression of tranquility and safety. It also features a highly legible, full dot-matrix LCD. Each aspect of the design has a clear purpose and intent.
