Flat-belt weigh feeder accuracy: How to achieve it, maintain it, and verify it
Belt weigh feeders [also called weighbelt feeders] are available in trough or flat styles. While a trough-belt weigh feeder prevents spillage, a flat-belt feeder provides better weighing accuracy for high-precision feeding applications. This article looks at how you can achieve, maintain, and verify flat-belt weigh feeder accuracy.
If you're looking for the ideal mass measurement device -- a scale -- you need one that's accurate. That is, the scale should exactly represent your material's weight. The results should also be repeatable. That is, the scale should exactly represent your material's weight after repeated weighings and extended time periods. And you should be able to easily verify and recalibrate the scale.
