ABSTRACT:
An impact type flow meter for a particulate material such as cereal comprises a supply device for dropping the particulate material, an inclined load detection plate for receiving the dropped particulate material, and a load detector for detecting a load of the particulate material exerted to the load detection plate. A bottom surface of the supply device is inclined at substantially the same degree with the load detection plate, and has at its lower end with a supply opening for dropping the particulate material onto the load detection plate. The bottom surface serves to guide the particulate material to the load detection plate at substantially the same inclination therewith. Thus, the flow meter has a buffer device for softening a dropping impact of the particulate material integrally incorporated in the particulate material supply device, and accordingly, the height is low and the whole apparatus is compact. The particulate material impinges upon the bottom surface of the supply device, diverges widthwise thereof and reaches the supply opening. Accordingly, the direction and position of dropping of the particulate material onto the load detection plate are fixed. Further, the flow-down speed of the particulate material is lessened, unevenness of the speed is averaged or uniformed, thereby the flow meter is high in measurement accuracy.
