The Belt Scale Drift Problem
Every yard boss knows the frustration: your belt scale shows one number, but end-of-month inventory tells a different story. Belt scales drift over time due to material buildup, belt stretch, temperature changes, and component wear. The question is always: how much?
What Causes Belt Scale Drift?
- Material buildup: Aggregite fines accumulate on weigh idlers and belt
- Belt stretch: Continuous operation causes belt elongation over time
- Temperature variation: Load cells and electronics respond to temperature changes
- Calibration age: Even properly maintained scales drift between calibration cycles
The Cost of Undetected Drift
A 2% belt scale error on a mid-size operation processing 50,000 tons per month means 1,000 tons of uncertainty. At $20/ton, that's $20,000 per month in potential variance—either overshipping customers or phantom inventory on your books.
How Drone Surveys Help
By comparing drone-measured volume changes to belt scale totals over the same period, you get an independent verification of scale accuracy. Our reconciliation tools make this comparison simple:
- Fly your site at consistent intervals (monthly recommended)
- Record belt scale totals for the same period
- Compare expected volume change vs. measured volume change
- Identify drift patterns and schedule calibration accordingly
Prove It to Corporate
When corporate questions your numbers, you need data—not excuses. Drone survey documentation provides the third-party verification to prove belt scale issues exist and justify calibration investment.
