To enable taking early measures against gas supply abnormality, while enabling detection of gas supply abnormality with no need of dispatching an inspector to the site, as well as to enhance convenience of gas users more than ever.SOLUTION: A gas supply abnormality determination system includes a supply abnormality determination unit CS3 which executes a first supply abnormality determination as supply abnormality determination to determine that there is a possibility of occurrence of gas supply abnormality in the vicinity of gas meters M having measured gas-pressure-related values in which a gas-pressure-related value at one measuring time point differs from other measuring time points regarding gas-pressure-related values corresponding to gas flow rates which are greater than zero at the measuring time points and in which a gas flow rate at one measuring time point is equal to gas flow rates at the other measuring time points at respective gas meters M regarding all of the gas meters M provided in one gas supply system out of determination information stored in a first storage unit CS2.SELECTED DRAWING: Figure 1 【課題】ガス供給異常に対する対応を早期に行うことができながらも、検査員が現地に赴くことなくガス供給異常を検知できると共に、従来に比べガス使用者の利便性の向上を図る。【解決手段】第１記憶部ＣＳ２に記憶された判定情報のうち、一のガス供給系統に設けられるすべてのガスメータＭに関し、ガスメータＭの夫々で一の測定時点におけるガス流量と他の測定時点におけるガス流量とが同一となっているときで、測定時点における零より大きいガス流量に対応するガス圧力関連値に関し、一の測定時点におけるガス圧力関連値と他の測定時点におけるガス圧力関連値とが異なる場合に、当該ガス圧力関連値を測定したガスメータＭの近傍においてガス供給異常が発生している可能性があると判定する供給異常判定としての第１供給異常判定を実行する供給異常判定部ＣＳ３とを備える。【選択図】図１
