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.

GRAVIMETRIC FEEDER
Stock Code: 7 G1
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.

ADVANTAGES AND USAGE AREAS
Pulse Electronic Gravimetric feeder has many important features compared to classical volumetric feeding systems. With this much more sensitive feeder, both the raw material, which is the input of the system, is saved and the system output is homogenized, allowing the facility to operate more efficiently. Instead of the feeder operating with 10% accuracy in the volumetric system, the gravimetric dosing system operating with 0.2% accuracy will save your business 9.8% per hour. Thanks to the special software it contains, it constantly controls the system output, preventing deviations from the target value and detecting changes that may occur in flow properties over time. Thus, linearity as well as accuracy is ensured in the system. Additionally, keeping the system under control during and after filling also contributes to the linearity of the flow. Other advantages of the gravimetric system are as follows.
It allows simultaneous weight measurement and feed amount control with a closed loop control system.
8 feeders can be controlled simultaneously.
Automatically adapts to material density changes that may occur over time, within wide ranges.
Material and output quantity can be controlled directly.
It has high linearity.
The interruption in material supply is directly understandable.
It has high accuracy, linearity and consistency.
