PURPOSE:To perform the correction of temp. with high accuracy, by taking out data at temp. concerned from correction factor data to integrate the same and performing output correction of one pulse when the integrated value reached a unit wt. CONSTITUTION:A pulse signal is received from a rotary encoder 41 outputting a two-phase pulse enabling the discrimination of the rising and falling of a piston rod 5 and the temp. of the cooling medium allowed to fill a weighing cylinder 1 is received from a temp. detector 31. Further, on reference to a memory element to which the numerical value obtained from known specific gravity data at every temp. is imparted corresponding to the kind of the cooling medium, one pulse is transmitted at each time when the cooling medium of a unit wt. is sent out, concretely, one pulse is transmitted at every 1g and the correction of temp. is performed with accuracy within a max. error of one pulse.
