Gravimetric feeder versus volumetric feeder
A gravimetric feeder, also know as a loss-in-weight 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.

Gravimetric Feeders vs Volumetric Feeders
Feeders are auxiliary equipment that dispense a measured amount of an ingredient—a resin, a colorant, or an additive—into resin entering a processing machine. The term "volumetric" refers to one way that a feeder measures and dispenses an ingredient. The other way is called "gravimetric.". Let's briefly look at both.
