How RETTAR 3DPro2300 Digitizes Bulk Material Silo Inventory

Eliminate inventory risks with the RETTAR 3DPro2300 Radar Scanner. Achieve 98% accuracy and unmanned safety with 3D modeling for smart bulk material silos.
Eliminate guesswork and manual risks. Discover how RETTAR’s 3D Radar Scanning technology provides real-time “X-ray vision” for industrial silos, ensuring 98% accuracy in even the most challenging environments.



In the global grain, brewing, and feed industries, managing deep silos is a constant challenge. When dealing with thousands of tons of sorghum or other bulk materials, managers often struggle with ”invisible inventory”—data that is estimated rather than measured. Traditional methods are either dangerously manual or technologically insufficient to handle the irregular surfaces of bulk solids.

5 Core Challenges Solved by RETTAR Technology

  1. Safety First: Manual inventory checks involve high risks of dust explosions, oxygen deficiency, and falls. RETTAR enables ”unmanned” auditing.
  2. Surface Irregularity: Single-point sensors cannot ”see” the peaks and valleys of material piles. The 3DPro2300 maps the entire surface for true volume calculation.
  3. Dust & Interference: Unlike optical sensors, RETTAR’s high-frequency radar waves pierce through heavy dust, steam, and darkness.
  4. Operational Efficiency: No need to stop loading or unloading; the scanner works continuously during active production.
  5. Data-Driven Auditing: Accurate inventory is critical for financial reporting and supply chain planning. RETTAR provides a digital audit trail.



Technical Innovation: The 3DPro2300 Advantage

  • High-Frequency Radar Precision: Utilizing advanced Frequency Modulated Continuous Wave (FMCW) technology, the scanner delivers millimeter-level distance accuracy. It is specifically designed to perform in the harsh, high-particle environments typical of sorghum storage.
  • Dual-Axis Robotic Scanning Platform: Equipped with a high-precision servo system, the scanner rotates 360° horizontally and tilts ±90° vertically. By capturing up to 16,200 independent measurement points in a single cycle, it creates a high-density cloud map that covers every square inch of the silo.
  • AI-Powered 3D Visualization: The point-cloud data is processed through RETTAR’s proprietary algorithms to reconstruct a 3D digital twin of the material surface. The system automatically calculates Real-time Volume (m³), Accurate Mass (Tons) and Average and Peak Material Levels



Strategic Value: Why Global Enterprises Choose RETTAR

  • Transforming Safety into Efficiency; By automating the measurement process, RETTAR eliminates the need for personnel to enter hazardous spaces. This not only protects lives but significantly reduces insurance and compliance costs.
  • Protecting Your Assets (±0.5% FS Accuracy); In a 10,000-ton silo, even a 5% error can lead to massive financial discrepancies. The 3DPro2300’s modeling accuracy of up to ±0.5% FS ensures that your physical inventory matches your books, protecting your bottom line.



Real-Time Digital Management

  • Visual Dashboard: View the real-time status of all silos from a centralized control room.
  • Seamless Integration: Data flows directly into your ERP, WMS, or MES via 4-20mA, RS485, or Ethernet.
  • Smart Alarms: Prevent overflows, empty-runs, or bridging with automated high/low-level alerts.

The RETTAR 3DPro2300 Radar Scanner is not just a sensor; it is a commitment to safety, accuracy, and digital transparency. As the grain industry moves toward Industry 4.0, RETTAR provides the foundation for data-driven decision-making.
