The operating principle of Puls Electronic Gravimetric Feeder with single screw is as follow; all of the feed system is standing one of the weighing platform. When the screw system works, each unit can also be weighed and decreasing the amount of material is calculated. This material amount is compared with the goal value and given the command to the engine for the calculated suitable speed. Simultaneous control and correction process with the target value is kept in a sensitive tolerance band.

Volumetric is the oldest dosing method before the Gravimetric. Dosing amount is calculated based on the volume that the feeding screw scans in unit time.
