An electromagnetic flow rate measuring apparatus (1) measures and calculates a flow rate of granules based on a measurement of capacitance which changes according to the quantity of the granules flowing at a granule passage (A-B). The measuring apparatus includes a granule flow pipe (2) which is coupled to the granule passage and is provided in the course of the granule passage, a capacitance detector (7) provided to the granule flow pipe, shutters (14,11) respectively provided at an upper end and a lower end of the granule flow pipe, for cutting off the flow of granules, the shutters being individually operable, and a load cell type weight detector (4) independently supporting the granule flow pipe. The shutters, the load cell type weight detector, and the capacitance detector are connected to a calculation control device (19). The measuring apparatus provides a flow rate which is not influenced by the moisture content or the density of the granules. <IMAGE> |
