Gravimetric Feeder | Thayer Scale
A gravimetric feeder is a self-calibrating feeder system that doses based on the weight in speed.

Dosing systems dispense predefined amounts of material in a specified ...
Loss-in-Weight Overview : Plastics Technology
Loss-in-Weight Overview. Principle. In loss-in-weight feeding, the entire feeder, hopper and material are continuously weighed. As the feeder discharges material, the rate of decline in system weight is computed, and feeder speed is adjusted to maintain the desired (set) rate. Advantages, Limitations and Considerations.
AUTOWEIGH FEEDER
Weighing feeders or weigh belts provide a means of weighing bulk material while being conveyed. This allows accurate rate of flow and totalized weight measurement without interrupting the flow of material in process. A weighing feeder also provides a means for controlling the rate of flow of the product being conveyed.

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.

The signal is then communicated noise-free via RS 485 to the controller. Every SFT provides a true 4,000,000:1 weight resolution in 80 ms and comes with a 5 year warranty.
Loss-in-weight feeding
A Schenck Accurate AccPro II was used as a "catch scale" for characterization of the performance of the LIW feeder. A catch scale is needed because the internal load cells used in gravimetric LIW feeders use different filtering algorithms to pretreat the gravimetric signal, which may not allow for accurate performance comparison between …
