Description of Endress+Hauser FMU41-ARB2A2 Ultrasonic Level / Flow Meter

The Endress+Hauser FMU41-ARB2A2 Ultrasonic Level / Flow Meter is a non-contact ultrasonic measuring instrument designed for continuous level and open-channel flow measurement in liquids and bulk solids. It operates using the time-of-flight principle, transmitting ultrasonic pulses toward the product surface and calculating level based on the echo return time.

The FMU41 is engineered for demanding industrial environments where reliability, measurement stability, and low maintenance are critical. Its non-contact measurement eliminates mechanical wear and reduces contamination risk, making it suitable for corrosive, abrasive, or aggressive media. The instrument integrates advanced signal processing algorithms to ensure accurate measurement even in the presence of turbulence, foam, or varying surface conditions.

Designed for ease of installation and commissioning, the device features local display capability and configurable output signals for seamless integration into PLC, SCADA, and distributed control systems. It is well suited for water and wastewater, chemical processing, environmental monitoring, and industrial storage applications.
