A meter reading device 2a reads an integrated-amount meter 1 every day and compares the present meter value with a previous meter value recorded in a recording section 20 to assess probability. If it is judged that the present meter value is probable, the meter value within the recording section 20 is updated. Also, the meter value within the recording section 20 is outputted to a host machine 45, for example once a month. |
