To provide a gas appliance discrimination device capable of automatically acquiring gas appliance information and discriminating a gas appliance even if there is a gas appliance which cannot be discriminated.SOLUTION: The gas appliance discrimination device comprises flow rate measurement means 102 for measuring a flow rate of liquid flowing in a flow channel 101 at a constant time interval, gas appliance information registration means 110 for registering a flow characteristic of gas consumed by a gas appliance as appliance information, and gas appliance discrimination means 111 for extracting the flow characteristic from data on the measured flow rate and comparing the appliance information registered in the gas appliance information registration means 110 with the same to discriminate a gas appliance. If the flow characteristic of the gas appliance extracted by the gas appliance discrimination means 111 is not registered as appliance information in the gas appliance information registration means 110, use time of the gas appliance is measured. When a gas appliance can be specified based on the flow characteristic and the use time of the gas appliance, the flow characteristic is registered as appliance information of the gas appliance.SELECTED DRAWING: Figure 1 【課題】判別できないガス器具が現れても、自動でガス器具情報を取得し、判別できるように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、ガス器具が消費するガスの流量特性を器具情報として登録するガス器具情報登録手段１１０と、計測された流量データから流量特性を抽出し、ガス器具情報登録手段１１０に登録された器具情報と比較しガス器具を判別するガス器具判別手段１１１とを備え、ガス器具判別手段１１１によって抽出されたガス器具の流量特性がガス器具情報登録手段１１０の器具情報として未登録の場合、該ガス器具の使用時間を計測し、該ガス器具の流量特性と使用時間に基づいてガス器具を特定できた場合、この流量特性を該ガス器具の器具情報として登録する。【選択図】図１
