Core Flow Weighing Technologies

Engineering Dynamic Weight Measurement

Our flow scale category utilizes specialized mechanical designs to weigh product without interrupting the flow:

• Batch-Type Flow Scales: The most accurate method for industrial monitoring. The machine collects a small batch (e.g., 50kg) in an internal hopper, weighs it statically, and then discharges it while the next batch is being collected.

• Impact Flow Meters: The grain falls onto a curved sensing plate. The horizontal force exerted on the plate is converted into a flow rate. This is ideal for space-constrained areas where continuous measurement is needed.

• Loss-in-Weight Feeders: Used for extreme precision in blending. The entire scale and its contents are weighed, and the speed of discharge is adjusted to maintain a constant, pre-set flow rate.

• In-Line Belt Scales: Integrated directly into conveyor belts to measure the weight of the material as it passes over a specific section of the conveyor.

Why Integrate ADDAMS Flow Scales?

Precision Data for Total Plant Control

Integrating flow scales at key points transforms a manual plant into a data-driven industrial facility.

1. Accurate Yield Calculation: By placing scales at the intake and after the cleaning stage, you can calculate exactly how much waste (screenings) was removed and your true "net yield."

2. Automated Blending: Ensure the perfect mix of different grain varieties by precisely controlling the flow rate of each component in the recipe.

3. Moisture Compensation: Integrated sensors can calculate the dry-matter weight, allowing you to account for moisture loss during drying or cooking processes.

4. Inventory Management: Track exactly how many tons of grain have moved from the silos to the processing line in a shift, day, or month, with digital logs for your management software.

Key Technical Features of the Flow Scale Series

Built for Accuracy and Connectivity

• High-Speed Load Cells: Equipped with advanced strain-gauge sensors that provide accuracy levels up to 0.1% even at high throughput speeds.

• Intelligent PLC Controllers: Feature built-in algorithms that compensate for vibration and material build-up, ensuring the scale doesn't drift over time.

• Communication Protocols: Fully compatible with SCADA and ERP systems via Modbus, Profibus, or Ethernet/IP, allowing for remote monitoring from any location.

• Dust-Tight Enclosures: Sealed housings prevent dust from escaping into the facility while protecting the sensitive weighing components from the environment.

Frequently Asked Questions – Seed & Grain Flow Scales

1. Is a flow scale the same as a bagging scale? No. A Bagging Scale is for filling sacks to a specific weight. A Flow Scale measures a continuous stream and keeps a running total of the mass (e.g., "50 tons have passed this hour").

2. How accurate are these machines? Our batch-type flow scales offer an accuracy of +/- 0.1% to 0.2%. This makes them precise enough for commercial yield calculations and inventory audits.

3. Do they slow down my production line? No. Our scales are sized to match your plant's capacity. The internal hoppers operate fast enough to ensure the "net flow" remains continuous without creating a bottleneck.

4. Can I use them for blending two different grains? Yes. This is a primary use case. By setting two flow scales to specific rates (e.g., 5 t/h of Wheat and 1 t/h of Rye), you can achieve a perfect 5:1 blend automatically.

5. Do they require frequent calibration? While our scales are very stable, we recommend a monthly check-calibration using a known weight to ensure the highest data integrity for your financial reporting.

6. Can they handle dusty or oily products? Yes. For oily products, we use specialized non-stick coatings and steeper hopper angles. For dusty products, the scale is fully enclosed with integrated aspiration ports.

7. Is it possible to see the data on my phone? Yes. Our controllers can be connected to your local network, allowing you to view real-time flow rates and totals on your mobile device or office computer.

8. What capacities are available? Our flow scales range from 1 ton per hour for specialty seed labs to 500+ tons per hour for ship-loading and industrial port terminals.
