An Introduction to Weigh Belt Feeders
By continuously measuring the weight of product over a known length of belt and the conveyor's speed, the weigh belt controller can work out the actual throughput of the feeder. It will then adjust the speed of the conveyor to match the desired feedrate, making small increases and decreases in speed to keep to that setpoint rate.
