Core Advantages & Features

1. Unmatched Reliability and Durability:

The FMU40-ARB2A2 is built with a robust, self-cleaning PFA sensor, resistant to corrosion and coating. Its advanced echo-processing software, "Echomax," intelligently filters out false echoes from fixed obstacles or agitators, ensuring a stable and reliable measurement signal even in noisy applications.

2. Simplified Operation and Commissioning:

Featuring the intuitive ToF (Touchless Operation) tool and a clear local display with plain text guidance, commissioning and parameterization are quick and error-free. The integrated self-diagnostics functions proactively inform users of the device's status, minimizing downtime.

3. Exceptional Versatility:

This transmitter excels in measuring liquids from ultrapure water to aggressive chemicals and liquids with light foaming. The compact design and narrow beam angle allow for flexible installation in small tanks or near walls.

4. Seamless Integration:

With a 4...20 mA HART output, the FMU40-ARB2A2 integrates effortlessly into existing control systems. Its digital communication enables advanced device diagnostics, remote configuration, and access to detailed process information.

5. Low Maintenance, High Efficiency:

As a non-contact technology, it is virtually wear-free. The absence of moving parts eliminates mechanical failure points, significantly reducing lifecycle costs and maintenance efforts.
