- 検出された計測信号を計測パルス信号として入力する流量演算処理部と共に、計測された温度が入力される温度演算処理部をマイコンにより構成し、該マイコンが、前記計測信号を前記計測温度に基づき補正し、該温度及び補正された計測信号をそれぞれ出力しかつ表示部に表示する温度補正機能付計測装置において、
前記マイコンは、高低2つの周波数の発振子を用いて、前記計測パルス信号の入力が有るときは、高い周波数の発振子を起動してアクティブモードにて動作する一方、最後に入力された計測パルス信号からある期間内に信号の再入力が無い場合、高い周波数の発振子の動作を停止して低い周波数の発振子による動作に切り替え、低消費電力モードに遷移し、かつ
前記計測信号を補正するための温度の計測時に、温度計測周期を短くし、温度変化に対する応答性を上げる一方、温度補正のための温度計測が終了すると、温度計測周期を長くして測定した温度を、前記温度表示部で表示するために用いる、
ことから成る温度補正機能付計測装置。 - 前記温度の計測を、抵抗体の抵抗の変化により検出する温度計測部を、前記マイコンにより構成した温度演算処理部に接続し、該抵抗と温度の関係を予め知るための前記温度計測部の校正時に、温度計測周期を短くして温度入力信号の変化に対する追従性を上げるよう構成した請求項1に記載の温度補正機能付計測装置。
