The gravimetric belt feeder Pfister GBF is auto calibrated by integrated calibration sensors. In case of a load cell discrepancy the feeder´s control switches to volumetric weighing mode automatically. In the volumetric mode, the feeder runs based on historic density. It automatically reverts back to gravimetric mode when the load cell data does not show further discrepancies.
