Top Ten Frequently on Feeder Accuracy - Pipe and Profile

Since, as mentioned above, volumetric feeders are open-loop devices from the viewpoint of discharge rate, headload variations and material buildup on the flights of a feed screw change the volume-per-revolution relationship, throwing off calibration without any outward sign. Gravimetric feeders automatically detect and adjust to these conditions.

Gravimetric analysis - Wikipedia

Gravimetric analysis describes a set of methods used in analytical chemistry for the quantitative determination of an analyte (the ion being analyzed) based on its mass. The principle of this type of analysis is that once an ions mass has been determined as a unique compound, that known measurement can then be used to determine the same analytes mass in a mixture, as long as the …
