Volumetric Scanners: The Future of Accurate Bulk Material Measurement
In industries that rely heavily on the movement and management of bulk materials — such as mining, agriculture, construction, and forestry — accuracy is everything. Traditional methods like weighbridges or manual estimation often fall short, leading to inefficiencies, disputes, and unnecessary costs. This is where volumetric scanners are transforming operations, offering fast, precise, and contact-free solutions for measuring material loads.
What Is a Volumetric Scanner?
A volumetric scanner is an advanced system that uses laser, radar, or 3D imaging technologies to calculate the volume of material loaded on a vehicle or stockpiled in a given area. Instead of weighing loads, the scanner generates a detailed 3D model of the material and computes the exact volume. When combined with known material density values, volumetric data can even be converted into an estimated weight.
Typically mounted above haul roads, conveyors, or stockyards, volumetric scanners capture high-resolution data as trucks pass beneath them or as materials accumulate in storage areas.
How Does a Volumetric Scanner Work?
The process behind volumetric scanning is both sophisticated and user-friendly. Here’s how it works:
1️. Baseline Scan: For vehicles, an empty (tare) scan is performed to create a 3D profile of the vehicle without material.
2️. Loaded or Stockpile Scan: The loaded vehicle or material stockpile is scanned. The scanner captures thousands — sometimes millions — of data points in seconds to create an accurate 3D model.
3️. Volume Calculation: The system compares the loaded scan to the empty profile or analyzes the 3D shape of a pile, calculating the precise volume.
4️. Reporting: Results are generated instantly, often including 3D visualizations, volume data, and estimated mass (if material density is known).
Advantages of Volumetric Scanners
Volumetric scanners offer a range of benefits that make them indispensable in modern bulk material operations:
High Accuracy: Volumetric scanners typically achieve measurement accuracy within ±1%. This level of precision reduces costly overloading, underloading, or disputes between suppliers and customers.
Speed and Efficiency: Measurements take place as vehicles drive past or during regular stockpile checks, with no need for stopping, manual measurement, or physical interaction. This keeps operations running smoothly.
Cost Savings: Compared to weighbridges or manual surveys, volumetric scanners reduce labor requirements and minimize maintenance costs. Once installed, they require little ongoing calibration.
Improved Safety: Since scanners work without physical contact, they eliminate the need for personnel to climb on loads or enter potentially dangerous stockpile areas.
Data and Insights: Volumetric scanners often integrate with fleet management and inventory systems, providing real-time data that can support better decision-making, logistics planning, and inventory control.
Where Are Volumetric Scanners Used?
Volumetric scanning technology is versatile and is applied in many sectors, including:
Mining and Quarrying: Measuring ore, coal, aggregates, or minerals transported by trucks or stored in stockpiles.
Construction: Monitoring deliveries and usage of sand, gravel, soil, or fill material to keep projects on budget.
Agriculture: Measuring grains, silage, and fertilizers moved by trucks or stored in bulk.
Forestry: Calculating the volume of wood chips, bark, or timber loads.
Volumetric Scanners vs. Weighbridges
While weighbridges measure mass directly, they require vehicles to stop and often need recalibration and maintenance. Volumetric scanners, on the other hand:
- Allow for dynamic scanning as vehicles move.
- Measure load size regardless of moisture content or contamination (important for materials like aggregates or biomass).
- Provide faster processing and reporting.
When material density is well-known and consistent, volumetric scanning can offer comparable accuracy to weighing — with added efficiency.
The Role of Technology and Innovation
Modern volumetric scanners continue to evolve alongside advances in technology. Many systems now feature:
Cloud connectivity: Enabling remote monitoring and reporting from anywhere.
Data analytics: Helping operators track trends in load volumes, reduce waste, and identify inefficiencies.
AI integration: Allowing predictive analysis and optimization of haulage or material handling operations.
Mobile apps: Giving managers and operators instant access to volumetric data on their smartphones or tablets.
The Future of Volumetric Scanning
The future of volumetric scanning lies in automation, AI-driven insights, and integration with smart operations. We can expect to see:
- Greater use of drones equipped with volumetric scanning sensors for stockpile measurement.
- Enhanced 3D imaging and modeling capabilities.
- Closer integration with autonomous haulage systems to improve load optimization.
These innovations will further increase the value of volumetric scanners, helping businesses maximize efficiency, reduce environmental impact, and stay competitive.
