Abstract

　器具判別技術の提供に際し、必要メモリ量などを減らしつつ、演算速度、器具判別精度の向上を図る。 　ガスメータ１００において、超音波流量計１０４は、流路１０２に流れるガスの流量を一定時間間隔で計測し、演算部１０８が計測された流量の一定時間毎の差分値を演算する。そして、差分値の大きさに応じた複数の差分値の区分と各区分を表すコードが対応付けられた流量区分表１１０ａに基づき、差分値変換部１１２は演算された差分値をコードに変換する。さらにコード列生成部１１４は、一定時間毎のコードの集合に基づき計測コード列を生成し、器具判別部１１６は、計測コード列と、ガス器具ごとの固有のコード列を示す器具固有コード列を比較し、ガスを使用するガス器具を判別する。
