| description | To provide an electromagnetic flow meter which accurately measures a flow rate and electrical conductivity of fluid without increase in size.SOLUTION: A signal generation circuit 11B generates an alternating rectangular wave current as a rectangular wave signal SG, which has constant amplitude (set current Is), at a pre-set signal frequency fs, so as to apply it to electrodes T1, T2 attached to a measurement pipe 2. An electrical conductivity detection circuit 11 samples detection voltages Vt detected from the electrodes T1, T2, so as to detect amplitude of the detection voltages Vt.SELECTED DRAWING: Figure 1
【課題】電磁流量計を大型化することなく、流体の流量と電気伝導率とを精度よく計測する。【解決手段】信号生成回路１１Ｂが、予め設定された信号周波数ｆｓで一定振幅（設定電流Ｉｓ）を有する交流の矩形波電流を矩形波信号ＳＧとして生成して、測定管２に取り付けられている電極Ｔ１，Ｔ２に印加し、電気伝導率検出回路１１が、これらＴ１，Ｔ２から検出した検出電圧Ｖｔをサンプリングすることにより検出電圧Ｖｔの振幅を検出する。【選択図】 図１ |
