Continuous level measurement system for powdery or granular materials
Ensure precise inventory management and enhanced safety in your silos with this system that offers real-time level detection for all powdery and granular materials, minimizing material waste and optimizing storage space.

Monitors and Measures Levels of Bulk Solids
The Continuous Level Measurement System ILS from WAMGROUP offers precise level detection for powdered and granular materials stored in silos. Utilizing a microprocessor-controlled mechanism, it accurately measures material levels by lowering a feel weight into the silo and retracting upon impact. Suitable for industries such as construction and glass processing, it is effective for materials like cement, lime powder, and ready-mix concrete. The ILS features an output of 0/4-20 mA and is ATEX-certified for zone 20/21 environments, ensuring safe operation. With a robust IP65 die-cast casing and intelligent supervision, it efficiently integrates into existing processes, minimizing maintenance and installation efforts. The system’s design eliminates mechanical stress on silo roofs and remains unaffected by dust or moisture variations, making it a reliable choice for high-accuracy applications in diverse industrial settings.
