Description of Endress+Hauser FMU40-ARB1A2 Ultrasonic Level / Flow Meter

The Endress+Hauser FMU40-ARB1A2 is a non-contact ultrasonic level and open-channel flow transmitter designed for continuous measurement of liquids, pastes, and coarse bulk solids. As part of the Prosonic M family, this instrument utilizes time-of-flight ultrasonic technology to provide reliable, maintenance-free measurement in challenging industrial environments.

The FMU40 is engineered for applications requiring high accuracy and operational stability, particularly where contact-based measurement technologies are unsuitable due to corrosive, aggressive, or contaminated media. Its integrated signal processing ensures stable measurement even in the presence of vapor, foam, turbulence, or dust.

With a robust enclosure, user-friendly display interface, and configurable output signals, the FMU40-ARB1A2 integrates seamlessly into PLC, DCS, and SCADA systems. It is well suited for water and wastewater treatment, chemical processing, environmental monitoring, and industrial storage applications.
