實(shí)際上大部分浮子流量計(jì)同一儀表可用于液體也可用于氣體，結(jié)構(gòu)上是通用的。只是我國(guó)浮子流量計(jì)行業(yè)標(biāo)準(zhǔn)等規(guī)定流量上限Qmax必須符合（1，，，4或6）×10nL/h的要求（n為正負(fù)整數(shù)或零），為液體（以水為表示）設(shè)計(jì)的儀表用于氣體（以空氣為表示）時(shí)，不符合上述要求，只能為氣體另行設(shè)計(jì)浮子和錐管，就分成液體和氣體兩種系列。國(guó)外有些制造廠同一儀表并列液、氣兩種流體的流量范圍，當(dāng)然流量值就不可能都是圓整值；國(guó)內(nèi)有些型號(hào)儀表也采用本辦法。但是液體用和氣體用設(shè)計(jì)還是有區(qū)別的，例如氣體儀表浮子設(shè)計(jì)得較輕，防浮子振蕩跳動(dòng)的阻尼件結(jié)構(gòu)各異等。測(cè)量蒸汽只能用專(zhuān)門(mén)設(shè)計(jì)的金屬管浮子流量計(jì)或在標(biāo)準(zhǔn)型儀表上加裝附加構(gòu)件，例如增加帶散熱片的液體阻尼件，以減少浮子跳動(dòng)；與指示轉(zhuǎn)換部分連接處隔以散熱片。熱式流量計(jì)好不好渦輪流量計(jì)一般由傳感器和顯示儀兩部分組成，也可做成整體式。</p><div

style="text-indent:25px">超聲流量計(jì)是通過(guò)檢測(cè)流體流動(dòng)對(duì)超聲束(或超聲脈沖)的作用以測(cè)量流量的儀表。超聲流量計(jì)主要由安裝在測(cè)量管道上的超聲換能器(或由換能器和測(cè)量管組成的超聲流量傳感器)和轉(zhuǎn)換器組成。超聲流量計(jì)和電磁流量計(jì)一樣，因儀表流通通道未設(shè)置任何阻礙件，均屬無(wú)阻礙流量計(jì)，是適于解決流量測(cè)量困難問(wèn)題的一類(lèi)流量計(jì)，特別在大口徑流量測(cè)量方面有較突出的優(yōu)點(diǎn)，它是發(fā)展迅速的一類(lèi)流量計(jì)之一。根據(jù)對(duì)信號(hào)檢測(cè)的原理，超聲流量計(jì)可分為傳播速度差法(直接時(shí)差法、時(shí)差法、相位差法和頻差法)、波束偏移法、多普勒法、互相關(guān)法、空間濾法及噪聲法等。</p><p> 橢圓齒輪流量計(jì)流量信號(hào)(即橢圓齒輪的旋轉(zhuǎn)速度n)的顯示，有就地顯示和遠(yuǎn)傳顯示兩種。就地顯示將齒輪的轉(zhuǎn)動(dòng)通過(guò)一系列的減速及調(diào)整轉(zhuǎn)速比機(jī)構(gòu)之后，直接與儀表面板上的指示針相連，并經(jīng)過(guò)機(jī)械式計(jì)數(shù)器進(jìn)行總量的顯示。遠(yuǎn)傳顯示主要是通過(guò)減速后的齒輪帶動(dòng)永久磁鐵旋轉(zhuǎn)，使得彈簧繼電器的觸點(diǎn)以與永久磁鐵相同的旋轉(zhuǎn)頻率同步地閉合或斷開(kāi)，從而發(fā)出一個(gè)個(gè)電脈沖遠(yuǎn)傳給另一顯示儀表.橢圓齒輪流量計(jì)計(jì)量精度高，適用于高粘度介質(zhì)流量的測(cè)量，但不適用于含有固體顆粒的流體，如果被測(cè)液體介質(zhì)中夾雜有氣體時(shí)，也會(huì)引起測(cè)量誤差。通常橢圓齒輪流量計(jì)的精度可達(dá)0.5級(jí)，是一種較為準(zhǔn)確的流量計(jì)量?jī)x表，但是，如果使用時(shí)被測(cè)介質(zhì)的流量過(guò)小，橢圓齒輪流量計(jì)儀表的泄漏誤差的影響就會(huì)突出，不能再保證足夠的測(cè)量精度。大量的投資被用于提升工廠的自動(dòng)化水平和現(xiàn)場(chǎng)數(shù)據(jù)的采集和實(shí)時(shí)監(jiān)控，以提升工廠的過(guò)程控制效率。</p><div

渦街流量計(jì)安裝對(duì)直管段的要求：正確地選擇安裝點(diǎn)和正確安裝流量計(jì)都是非常重要的環(huán)節(jié)，若安裝環(huán)節(jié)失誤輕者影響測(cè)量精度，重者會(huì)影響流量計(jì)的使用壽命，甚至?xí)p壞流量計(jì)。渦街流量計(jì)安裝對(duì)直管段的要求是非常重要的。它的詳細(xì)要求如***量計(jì)對(duì)安裝點(diǎn)上的上下游直管段一定的要求，否則會(huì)影響測(cè)量精度。若流量計(jì)安裝點(diǎn)上的上游有漸縮管，流量計(jì)上游應(yīng)有不小于15D(D為管道直徑)的等徑直管段，下游應(yīng)有不小于5D的等徑直管段。若流量計(jì)安裝點(diǎn)上的上游有漸擴(kuò)管，流量計(jì)上游應(yīng)有不小于18D(D為管道直徑)的等徑直管段，下游應(yīng)有不小于5D的等徑直管段若流量計(jì)安裝點(diǎn)上游有90°彎頭或下行接頭，流量計(jì)上游應(yīng)有不小于**的等徑直管段，下游應(yīng)有不小于5D的等徑直管段。若流量計(jì)安裝點(diǎn)上游在同一平面上有90°彎頭，流量計(jì)上游應(yīng)有不小于25D的等徑直管段，下游應(yīng)有不小于5D的等徑直管段。流量調(diào)節(jié)閥或壓力調(diào)節(jié)閥盡量安裝在流量計(jì)下游5D以遠(yuǎn)處，若必須安裝在流量計(jì)的上游，流量計(jì)上游應(yīng)有不小于25D的等徑直管段，下游應(yīng)有不小于5D的等徑直管段。流量計(jì)上游若有活塞式或柱塞式泵，活塞式或羅茨式風(fēng)機(jī)、壓縮機(jī)，流量計(jì)上游應(yīng)有不小于25D的等徑直管段，下游應(yīng)有不小于5D的等徑直管段。從機(jī)械式流量計(jì)到電子技術(shù)流量計(jì)的革新是流量計(jì)重要的發(fā)展趨勢(shì)之一。寧夏智能靶式流量計(jì)特點(diǎn)</p><p
