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.
High-precision gravimetric feeders | Gericke
Gericke's gravimetric feeders with a tare-compensated weighing system are perfectly suited for applications where emphasis is put on both highest accuracy and exceptional robustness. Because the dead load of the feeder is mechanically compensated, the whole load cell range is available for measuring the weight of the bulk material only.

Should coal-fired power plants use gravimetric feeders?
Therefore, even if an operation were processing coal of equal dimensions, each piece may have a different density. In light of this reality, gravimetric weigh feeders are the better option. These instruments calculate a substance's total weight, using that value to determine how much coal to feed. Substituting a gravimetric feeder with a ...
