For studying the fluidity of powder and granule, the measurement of flow rate through an orifice is very crucial. However, until now we have not been able to measure the flow rate accurately. Formerly, flow rate was determined according to the quantity of flow over a 10-60 second time period. In this study, we have developed an accurate method for measuring flow rate over a very short time period (0.13 seconds). By this measurement apparatus, we can observe changes in flow rate behavior that was not possible in previous studies. From this study, a new flow behavior became clear and it was proved that the previous theory can be applied to a very short time period.
