To provide a gas appliance discrimination device with which it is possible to integrate the flow rate values of a gas appliance with high accuracy.SOLUTION: The gas appliance discrimination device comprises: flow rate measurement means 102 for measuring the flow rate of a fluid flowing in a passage 101 at given time intervals; average flow rate calculation means 121 for collecting a prescribed number of measured flow rate data and calculating an average flow rate; gas appliance discrimination means 110 for discriminating a gas appliance from the measured flow rate data; appliance flow rate calculation means 122 for calculating the flow rate of the appliance from the calculated average value and the discriminated result; appliance flow rate integration means 123 for integrating the flow rates of a specific gas appliance when the gas appliance is discriminated as a specific gas appliance; and gas appliance in use determination means 124 for determining whether or not the specific gas appliance is in use. When, while newly registered as the flow rate of a gas appliance, the specific gas appliance is determined to be in use and the result of discrimination by the gas appliance discrimination means 110 is a prescribed result, the appliance flow rate to be registered is integrated as that of the specific gas appliance.SELECTED DRAWING: Figure 1 【課題】ガス器具の流量値を精度よく積算することが可能なガス器具判別装置を提供する。【解決手段】流路１０１に流れる流体の流量を一定時間間隔で計測する流量計測手段１０２と、計測された流量データを所定個数集め、平均流量を算出する平均流量算出手段１２１と、計測された流量データからガス器具を判別するガス器具判別手段１１０と、算出された平均値と判別された結果から該当器具の流量を算出する器具流量算出手段１２２と、ガス器具が特定のガス器具と判別された場合に、特定のガス器具の流量を積算する器具流量積算手段１２３と、特定のガス器具を使用中か否かを判別するガス器具使用中判別手段１２４を備え、新たにガス器具の流量として登録された際に、特定のガス器具を使用中であると判別され、且つガス器具判別手段１１０による判別結果が所定の結果の場合は、登録する器具流量を特定のガス器具のものとして積算する。【選択図】図１
