Ultrasonic Level

Ultrasonic Level Measurement

Endress+Hauser’s ultrasonic level devices are non‑contact instruments that determine level by time‑of‑flight. A transducer emits sound pulses, measures the echo return, and converts distance to level or volume with built‑in temperature compensation. The technology works on liquids and, with a clear acoustic path, some bulk solids.

They’re useful because nothing touches the medium—ideal for corrosive, abrasive, sticky, or hygienic processes. No moving parts mean low maintenance. Smart algorithms suppress false echoes, track foam or turbulence, and deliver dependable readings where floats or differential pressure struggle. Setup is quick, with guided menus and diagnostics.

Endress+Hauser offers compact one‑piece sensors and remote sensor‑controller pairs with relays, pump control, and open‑channel flow computation. Outputs include 4–20 mA/HART and digital protocols, with IP‑rated enclosures and hazardous‑area approvals. Accessories like stilling wells and aiming kits broaden use.

Typical uses include water/wastewater lift stations, wet wells, sewer infrastructure, chemical storage, and level in hoppers or silos. Common for open‑channel flow at flumes/weirs, sumps, overfill prevention, and pump alternation. Best results are in clean air; heavy vapor or dense foam may favor radar.
