Ultrasonic measurement Time-of-Flight Prosonic FDU93

Field of Application :

The FDU93 ultrasonic sensor is designed for continuous, non-contact, and maintenance-free level measurement of fluids, pastes, sludges, and bulk materials ranging from powdery to coarse textures. It is also suitable for flow measurement in open channels and weirs. The sensor ensures reliable measurement performance, unaffected by dielectric constant, density, or humidity. Additionally, its self-cleaning effect prevents build-up, ensuring long-term accuracy.

This sensor is ideal for:

• Bulk material level measurement in silos, stockpiles, crushers, and conveyor belts
• Flow measurement in open channels and at weirs
• Low structural height applications
• Explosion hazardous areas, with certified safety compliance
