What is it: a sensor installed over the hoppers. It operates with a sonar system that measures the distance from the sensor to the reading point using continuous ultrasound, returning a value that goes from 0 to 100%. The system is not affected by dust or sprays of water.

What is it used for: the system is used to measure the correct level of material present in the various storage silos. The data detected can be used for partial work cycle shutdown if there is only a small amount of material present or to reduce the material flow rate in the event of excessive product. Considering storage silos, the levels can also be displayed in order to determine silo unload priority; the values can be viewed via external displays (with reading up to 80 m) or displays installed directly on the lorries used for unloading via radio connection.

Advantages:
Increase in production
Less wear of components
Energy saving
Increase in safety (due to possible spillover and fall of material from above)
Less staff assigned to plant control
Automation of the hopper unloading and storage phases
