Abstract:
(EN) A measuring device 100 is provided with: a measuring unit 10 which causes ultrasound waves to propagate through a medium 98 flowing through a pipe 99, and receives said ultrasound waves; a difference calculating unit 23a which calculates a difference signal obtained from the difference between the waveforms of received signals comprising at least two received ultrasound waves; and an identifying unit 23d which identifies a reception timing with respect to the transmission of the ultrasound waves on the basis of a target signal component included in the difference signal. By identifying the reception timing on the basis of the target signal component included in the difference signal, the flow rate of the medium 98 can be measured accurately using the reception timing.
(FR) L'invention concerne un dispositif de mesure (100) qui comprend : une unité de mesure (10) qui amène des ondes ultrasonores à se propager à travers un milieu (98) s'écoulant à travers un tuyau (99), et reçoit lesdites ondes ultrasonores ; une unité de calcul de différence (23a) qui calcule un signal de différence obtenu à partir de la différence entre les formes d'onde de signaux reçus comprenant au moins deux ondes ultrasonores reçues ; et une unité d'identification (23d) qui identifie une synchronisation de réception par rapport à la transmission des ondes ultrasonores sur la base d'une composante de signal cible incluse dans le signal de différence. En identifiant la synchronisation de réception sur la base de la composante de signal cible comprise dans le signal de différence, le débit du milieu (98) peut être mesuré avec précision à l'aide de la synchronisation de réception.
(JA) 測定装置100は、配管99内を流れる媒質98中に超音波を伝搬させて受信する測定ユニット10、受信された少なくとも2つの超音波の受信信号の波形の差分をとった差分信号を算出する差分算出部23a、及び差分信号に含まれる対象信号成分に基づいて、超音波の送信に対する受信タイミングを特定する特定部23dを備える。差分信号に含まれる対象信号成分に基づいて受信タイミングを特定することで、この受信タイミングを用いて媒質98の流速を精度よく測定することができる。
