In this video, we provide an in-depth look at the Endress Hauser FMU40-4NB2C2 Prosonic Ultrasonic Level Transmitter. You'll see how this device utilizes time-of-flight measurement technology for non-contact level detection of liquids, pastes, and bulk solids. We'll demonstrate its menu-guided operation, envelope curve visualization for diagnosis, and explain its integration into process control systems via HART communication.
