style="text-indent:25px">帶打印便攜超聲波流量計(jì)具有測量精度高、一致性好、電池供電、操作簡單、攜帶方便等特點(diǎn)，是目前國內(nèi)體積較小、質(zhì)量較輕，真正意義上的便攜超聲波流量計(jì)。利用了低電壓、多脈沖時(shí)差原理，采用高精度和超穩(wěn)定的雙平衡信號差分發(fā)射、差分接收數(shù)字檢測技術(shù)來測量順流和逆流方向的聲波傳輸時(shí)間，根據(jù)時(shí)差計(jì)算出流速。具有穩(wěn)定性好、零點(diǎn)漂移小、測量精度高，量程比寬抗干擾性強(qiáng)等特點(diǎn)。當(dāng)超聲波波束在液體中傳播時(shí)，液體的流動(dòng)將使傳播時(shí)間產(chǎn)生微小變化，其傳播時(shí)間的變化正比于液體的流速，零流量時(shí)，兩個(gè)傳感器發(fā)射和接受聲波所需的時(shí)間完全相同；介質(zhì)流動(dòng)時(shí)，逆流方向的志波傳輸時(shí)間大于水流方向的聲波傳輸時(shí)間。</p><p

style="text-indent:25px">根據(jù)一元流動(dòng)的連續(xù)方程，當(dāng)流通截面恒定時(shí)，截面上的平均流速與體積流量成正比，于是各種與流速有關(guān)的物理現(xiàn)象便可以用來建立流量計(jì)。例如：超聲波流量計(jì)、渦輪流量計(jì)、動(dòng)壓測量管、漩渦流量計(jì)和節(jié)流式流量計(jì)等均屬于此類。目前流量儀表中以這類儀表**多，它們有較寬的使用條件，有用于高溫高壓流體的，也有精度較高的，有的能量損失很小，有的可適應(yīng)臟污介質(zhì)等等。使流體流動(dòng)得到某種加速度的力學(xué)效應(yīng)與質(zhì)量的關(guān)系，是這種方法的物理基礎(chǔ)，按這種原理制成的流量計(jì)有質(zhì)量流量計(jì)和回轉(zhuǎn)管式流量計(jì)等。自貢流量儀表銷售</p><p style="text-indent:25px">自貢流量儀表銷售</p><p style="text-indent:25px">流量測量的方法很多，儀表的種類也很多，結(jié)合流量的定義，常用的流量測量方法可歸納為容積法，流速法和質(zhì)量流量法等。如果流體是以固定體積從流量計(jì)中逐次排放流出，則對排放的次數(shù)計(jì)數(shù)，就可以求得通過儀器的流體總量。若測量排放的頻率，即可顯示流量。這種方法叫做容積法。如刮板流量計(jì)。橢圓齒輪流量計(jì)和標(biāo)準(zhǔn)體積管等，都是按此原理工作的。這類儀表所顯示的是體積流量的總量。容積法的特點(diǎn)是流動(dòng)狀態(tài)對測量的影響較小，精確度較高，這類流量計(jì)一般不宜用于測量高溫高壓流體和臟污介質(zhì)的流量，測量流量的上限也不大。自貢流量儀表銷售</p><p
