PURPOSE: A digital meter capable of a precise correction of a measured flux and an automatic correction system thereof are provided to correct the measured flux on a real time basis by correcting an instantaneous flux based on an average value of the information of flux errors and to automatically correcting errors of the digital meter. CONSTITUTION: A digital meter capable of a precise correction of a measured flux comprises a flux detecting unit(20), a flux information acquisition unit(310), an error rate information storage unit(40), a flux information calculation unit(320), and a flux display unit(50). The flux detecting unit detects the number of the rotation of an impeller based on a flow. The flux information acquisition unit obtains first flux information based on the sensed number of the rotation of the impeller. The average information of a flux error rate, which is an average value of the information of flux errors in a flux section per each unit hour, is stored in the error rate information storage unit. The flux information calculation unit reads the average information of the flux error rate of the flux section corresponding to the obtained first flux information and calculates accumulated flux information based on second flux information corresponding to the read average information of the flux error rate. The flux information calculation unit displays the calculated the accumulated flux information.
