Description of Endress+Hauser FMU44-4VB2C42A Ultrasonic Level / Flow Meter
The FMU44-4VB2C42A from the Prosonic M series is a non-contact ultrasonic level and flow measurement transmitter designed for continuous monitoring of liquids, pastes, and bulk solids. Utilizing time-of-flight ultrasonic technology, the instrument calculates level or open channel flow by measuring the echo return time from the material surface.
Engineered for industrial environments, the FMU44 provides reliable performance in challenging applications involving dust, vapors, turbulence, and temperature fluctuations. Its non-contact measurement principle eliminates mechanical wear, making it ideal for corrosive, abrasive, or sticky media.
The transmitter features advanced echo processing algorithms for stable signal interpretation and includes built-in linearization for open channel flow measurement. Configuration is achieved through a user-friendly display interface, simplifying commissioning and maintenance.
The FMU44-4VB2C42A is suitable for mounting on tanks, silos, lift stations, and open channels, delivering high operational reliability in water and wastewater, chemical processing, and general industrial sectors.
