PROBLEM TO BE SOLVED: To determine an abnormality of a smart meter with high accuracy by utilizing data integrated by the smart meter.SOLUTION: In a gas meter system 100, a gas meter 110 comprises: a flow rate value detection part which detects a flow rate value of gas; a pressure value detection part which detects a meter pressure value of the gas; and a meter communication part which transmits the detected flow rate value and the meter pressure value to a center device, and a center device 114 comprises: a center communication part which receives the flow rate value and the meter pressure value from the gas meter; a meter extraction part which extracts one object meter to be a diagnostic object, and one or a plurality of reference meters located in the vicinity of the object meter from a plurality of gas meters; and an abnormality diagnostic part which diagnoses whether or not the object meter is abnormal based on correlation between the flow rate value and the meter pressure value in the object meter and the reference meters. |
