3DLevelScanner: Multiple Point Measurement for Accurate Volume

Advanced acoustics technology measures material topography in dusty environments for effective non-contact volume measurement.

Need volume accuracy in irregularly piled materials?  3D visualization to detect sidewall buildup?

Advanced acoustics-based technology is a proven performer in dusty powders and bulk solids.

5 Ways 3D is different:

  1. Most level sensors only measure a single point
  2. Optional 3D visualization of material topography
  3. Detects cone up, cone down, and sidewall buildup
  4. Provides minimum, maximum, and average distances
  5. Accounts for surface irregularities for accurate bin volume

3D excels in unevenly piled material:

  • Grain, seed, feed, and food processing
  • Ethanol, bioenergy, and power plants
  • Aggregates and cement
  • Mining and metals
  • Chemical processing and plastics manufacturing
  • Pulp, paper, and wood pellets

Inventory Management
Ensure adequate supply for production, prevent material shortages.


Remote Monitoring
Manage inventory while in the plant, while traveling, or away from the office.


Vendor Managed Inventory
Engage suppliers in replenishing the supply chain to optimize purchasing.


Storage Dome Monitoring
Monitor conveyed or truck loaded materials in large storage structures.


Pile Monitoring
Manage pile height, size, and volume of bulk materials.
