Difference Between Gravimetric And Volumetric Feeder

A gravimetric feeder is a device that precisely dispenses a predetermined amount of material, such as powdered solids, granules, and liquids. Unlike a volumetric feeder, which dispenses a fixed volume of material, a gravimetric feeder uses the weight of the material to determine the amount of material to be dispensed.
