Difference Between Gravimetric and Volumetric Feeder
Jun 19, 2018· The key difference between gravimetric and volumetric feeder is that we measure the rate of a gravimetric feeder in the unit of volume per unit time whereas we measure the rate of a volumetric feeder in the unit of weight per unit time Feeders are useful to handle bulk solids There are two forms of feeders and we call them as gravimetric feeders and volumetric feedersTo be able to choose wisely between a gravimetric feeder and a volumetric feeder, it is important to know the budget and objective of the user As mentioned previously, both dosing systems from Movacolor have a stepper motor and a unique dosing cylinderDifference between Gravimetric and Volumetric feeder | Mova
