Endress+Hauser ultrasonic level sensors are advanced non-contact level measurement instruments designed to provide reliable, accurate, and maintenance-free monitoring of liquids, slurries, and solids in tanks, silos, and open vessels. Utilizing high-frequency sound waves, these sensors measure the distance to the surface and convert it to precise level values, ideal for industrial process control and automation.

✔ Non-Contact Measurement
– No contact with process media – ideal for corrosive, sticky or abrasive liquids
– Zero wear and minimal maintenance

✔ High Accuracy & Repeatability
– Stable measurement even with vapors, foam, or agitation
– Reliable performance over a wide range of conditions

✔ Wide Application Range
– Suitable for liquids, slurries, and bulk solids
– Works in atmospheric tanks, open channels, and vessels

✔ Flexible Output Options
– 4–20 mA with HART®
– Digital communication (Modbus, Profibus, FOUNDATION™ Fieldbus)
– Relay outputs and frequency outputs (model dependent)

✔ Robust Industrial Design
