1. Separate plant vibration noise from true weight loss. A LIW feeder's operation depends on accurate measurement of the material weight in the hopper, so the feeder and weight-sensing device must be isolated from external forces and vibration. Position the feeder so that no external forces or friction can influence weighing. Isolate

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. …

To use a volumetric feeder, the user must know the rate at which an ingredient must be dispensed into a process (e.g., 10 grams/60 sec.) and how much volume that weight represents. To set that rate in a volumetric feeder, the user turns on the feeder auger and begins "catching" samples in a container for a timed period (e.g., 60 seconds).
