## Weighfeeders

The load cell measures the weight of a fixed-length belt section, yielding a figure of material weight per linear distance on the belt. A tachometer (speed sensor) measures the speed of the belt. The product of these two variables is the mass flow rate of solid material “through” the weighfeeder:

Where,

W = Mass flow rate (e.g. pounds per second)

F = Force of gravity acting on the weighed belt section (e.g. pounds)

S = Belt speed (e.g. feet per second)

d = Length of weighed belt section (e.g. feet)
