Compact, Reliable Point Level Detection Using Ultrasonic Technology
For plant engineers, maintenance teams, and operations managers who require dependable, low-maintenance level monitoring in tanks, vessels, or pipelines, the Sonac 110 Ultrasonic Level Switch provides a compact and reliable solution. This non-intrusive point level detector uses advanced ultrasonic technology to deliver precise on/off level detection in liquids, slurries, and certain solids without relying on moving parts. Unlike traditional float or mechanical switches, the Sonac 110 resists fouling, vibration, and turbulence, ensuring consistent performance, operational safety, and a cost-effective, long-life solution in challenging industrial conditions.
Detects product presence without mechanical wear, eliminating failure modes common to moving parts.
No moving parts and resistance to sticking or buildup ensures maintenance-free operation and extended equipment lifecycle.
Works reliably across a wide range of media, including water, hydrocarbons, chemicals, and slurries.
Provides dependable high- or low-level alarms to prevent costly overfill events or damage from pump dry-run conditions.
Immune to common nuisances like turbulence and vibration, ensuring reliable switching accuracy.

We have tried to answer the most common questions we are asked here.
The Sonac 110 sends a high-frequency ultrasonic signal across a small gap or along the probe tip. When liquid covers the sensor, it changes the way the sound wave propagates. The device’s electronics detect this change instantly to trigger an alarm, providing accurate on/off level detection without needing any mechanical actuation.
Yes. The Sonac 110 is available with versions certified for hazardous areas, including ATEX for European compliance and NEC Class I Div 1 options for North America, ensuring safe use in explosive environments.
The primary benefit is reliability and zero maintenance. Unlike float switches, the Sonac 110 has no moving parts to wear out, stick, or become clogged by viscous liquids or buildup. This makes it far more dependable for long-term level monitoring in challenging industrial media.
