PROBLEM TO BE SOLVED: To simplify or dispense adjustment of a filling rate detecting circuit when a powder granule body packed tube as an object for detecting a filling rate is changed to a tube with a different kind of a standard. SOLUTION: A powder granule body filling rate detecting device comprises a detecting coil (4) letting the transferring powder granule body packed tube pass, which detects impedance of the detecting coil and generates a powder granule body filling rate signal (Vm) corresponding to the impedance, measuring circuits (6 to 21) arranged for detecting a filling rate of a normal standard (A), which have converting functions converting a powder granule body filling rate signal (Vmi) generated by the measuring circuits (6 to 21) of the powder granule body packed tube with standards (B, C, D, and to N)different from the normal standard (A) into a correction signal (Vmai) with a level equivalent to the filling rate of the powder granule body packed tube with the normal standard (A), a correction means (22 to 25) converting with the specified converting function, and a means (26) specifying converting functions.
