    Features and Benefits of A Gravimetric Feeder?Features and Benefits of A Volumetric Feeder?Advantages and Disadvantages of Gravimetric Feeder and Volumetric Feeder?Volumetric FeederA gravimetric feeder is a self-calibrating dosing system that doses based on weight in speed. A volumetric feeder, on the other hand, does this based on volume in speed. In gravimetric dosing, the weight of the dosed additive is measured using a load cell that is the foundation of the entire system. Weight is calculated using loss-in-weight technology, which measures the reduced weight while dosing. In the self-calibrating gravimetric feeSee more on movacolor

  • Gravimetric Feeders: The Achilles' Heel of Continuous

    During the fill cycle, the downstream feeder is operated in a volumetric mode (i.e., at a constant speed). The feeder then operates in gravimetric mode (i.e., its speed is controlled by measuring the loss in weight of material inside the hopper) after the downstream hopper has been filled. A schematic of a gravimetric feeder is given in Figure 1.
