摘要：

The document shows a method for calibrating the feed rate of a device (1, 1) for air flow-borne dispensing of granular or powdery material (100), such as seed, fertilizer or pesticide. The method comprises producing a calibration air flow (Fs), feeding a quantity of the granular material (100) with the aid of the calibration air flow (Fs) for a calibration period to a separator (8) and, in the separator (8), substantially separating the granular material (100) from the calibration air flow (Fs). The calibration air flow (Fs) is produced with the aid of underpressure applied to a low-pressure side of the separator (8).
