PROBLEM TO BE SOLVED: To avoid difficulty for calibration when in use even with different operation modes. SOLUTION: The electronic metering device includes driving devices (7 and 8), displacer devices (9 and 10), a holder (5), a data memory (23), electric selecting devices (18, 19, 20, and 21), and an electric controlling device (22). The electric selecting devices, the data memory, an electric motor, and an electric displaying device (16) are connected to the electric controlling device. From the motion of the displacer section (10) due to the electric motor (8) and/or the calibration data retrieved from the data memory (23) selected through the electric selecting devices (18, 19, 20, and 21), the display of metered volume is controlled from an electric displaying device (23) by means of the electric controlling device.
