Volumetric feeder To use a  volumetric feeder ,  the user must know the rate at which an ingredient must be dispensed into a process and how much volume that weight represents. To set the rate in a volumetric feeder, the user turns on the feeder auger and begins catching samples in a container for a timed period. After each catch, the user weighs the sample and then adjusts the auger speed, up or down, until the feeder delivers the correct amount of the ingredient into the sample container. The sampling process must be repeated each time that that there is a change in bulk density or a change in the ratio of the ingredient in the process. Attributes of the volumetric concept are as follows: Cannot automatically compensate for material density variation Other factors affecting calibration or Sensitive to material build-up No direct measurement of material throughput Limited turn-down, insensitive to system non-linearity No innate detection of material supply interruption
