關(guān)于超聲波流量計(jì)固定式和便攜式有什么不同 </p> <p> （1）合適使用的場(chǎng)合不一樣 </p> <p> 固定式超聲波流量計(jì)用于安裝在某一固定方位，對(duì)某一特定管道內(nèi)流體的流量進(jìn)行長(zhǎng)時(shí)間不間斷的計(jì)量；便攜式超聲波流量計(jì)具有很大的機(jī)動(dòng)性，首要用于對(duì)不一樣管道的流體流量作臨時(shí)性丈量。 </p> <p> （2）供電方法不一樣 </p> <p> 固定式超聲波流量計(jì)要求長(zhǎng)時(shí)間接連運(yùn)轉(zhuǎn)，所以要運(yùn)用220V交流電源，便攜式超聲波流量計(jì)既能夠運(yùn)用現(xiàn)場(chǎng)的交流電源，也備有內(nèi)置充電電池，能夠接連作業(yè)5～10h［小時(shí)］，方便了不一樣場(chǎng)合臨時(shí)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(jì)，通常都有4-20mA信號(hào)輸出等功用，供遠(yuǎn)傳顯現(xiàn)運(yùn)用，但其內(nèi)部只能存貯一條管道的參數(shù)；便攜式超聲波流量計(jì)**為了現(xiàn)場(chǎng)檢查當(dāng)時(shí)流量和短時(shí)間內(nèi)的累計(jì)流量，故一般無(wú)輸出信號(hào)功用，但為了方便丈量不一樣管道流量，它具有豐厚的儲(chǔ)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(shí)調(diào)出運(yùn)用。
