style="text-indent:25px">電磁流量計是根據(jù)法拉弟電磁感應定律制成的一種測量導電性液體的儀表。泰州液體渦輪流量計廠家哪家好</p><p> 關于超聲波流量計固定式和便攜式有什么不同 </p> <p> （1）合適使用的場合不一樣 </p> <p> 固定式超聲波流量計用于安裝在某一固定方位，對某一特定管道內流體的流量進行長時間不間斷的計量；便攜式超聲波流量計具有很大的機動性，首要用于對不一樣管道的流體流量作臨時性丈量。 </p> <p> （2）供電方法不一樣 </p> <p> 固定式超聲波流量計要求長時間接連運轉，所以要運用220V交流電源，便攜式超聲波流量計既能夠運用現(xiàn)場的交流電源，也備有內置充電電池，能夠接連作業(yè)5～10h［小時］，方便了不一樣場合臨時性流量丈量的需要。 </p> <p> （3）有些功用不一樣 </p> <p> 因定式超聲波流量計，通常都有4-20mA信號輸出等功用，供遠傳顯現(xiàn)運用，但其內部只能存貯一條管道的參數(shù)；便攜式超聲波流量計**為了現(xiàn)場檢查當時流量和短時間內的累計流量，故一般無輸出信號功用，但為了方便丈量不一樣管道流量，它具有豐厚的儲存功用，能夠一起存貯數(shù)十條不一樣管道的參數(shù)，供隨時調出運用。 </p> <p> <br />
