摘要：A weighing apparatus for a vertical material feeder which feeds particulate material from a storage bin through a prefeeder agitator and a feeder bowl to an outlet pipe. The weighing apparatus includes a radiation source and detection means positioned on opposite sides of the path of travel of the material through the feeder bowl for generating a signal representing the mass of material in the path. The weighing apparatus also includes a speed sensor for generating a signal representing the speed of the material through the feeder bowl and means responsive to the mass signal and the speed signal for generating a signal representing the rate at which the material is being fed through the feeder bowl.
