PURPOSE:To measure true weight of granular body by detecting accelerations resulting from external disturbances such as impact or vibration to be effected to a weight measuring part by means of an acceleration meter provided to the weight measuring part, and excluding an apparent variable quantity of weight. CONSTITUTION:The weight of a measuring hopper 4 including a measuring feeder 5 is detected along with contained granular body by a load cell 6, and the output signal is sent to a control processing part 7. An acceleration meter 8 is provided to the measuring hopper 4. When external disturbances such as impact or vibration break out in the control system, a signal of a variable quantity of weight is subtracted and removed from an apparent weight signal outputted from the load cell 6, and the true weight of the granular body is obtained. |
