PURPOSE:To correct automatically a head value in accordance with the change of a transport rate, and to measure accurately the filling amt. by correcting in accordance with an incremental filling value for every fixed cycle without making the head value constant. CONSTITUTION:The output of a converter 1a is amplified to voltage proportional to the filling amt. of a granular body A, converted into a digital signal by an A/D converter 20, and stored in a storage device 23 or calculated by a CPU24. A setting device 25 for setting a desired value Wo of the granular body A to be filled into a vessel B, a motor 5, and an output part 26 to turn on or off an opening and closing valve 11 etc. are provided. |
