Acrison’s various Model 400 Series of Weigh Feeders, Gravimetric Feeders operate on a ‘Weight-Loss-Differential’ (or loss-in-weight feeding) basis; they are designed with an integral Acrison dry solids feeder, or a positive displacement liquid pump, as the metering mechanism of these precision all-digital weigh feeders, precisely controlled by an Acrison designed and manufactured advanced state-of-the-art controller.
‘Weight-Loss’ weigh feeders, gravimetric feeders operate strictly on the basis of the loss of a specific amount of weight (product) in a specific amount of time. There are no other factors that enter the equation. Such weigh feeders do not utilize a ‘zero reference’ as the basis for feed rate calibration; they operate strictly on the basis of ‘weight-loss’ over time.
