超聲波流量計(jì)是基于超聲波在流動(dòng)介質(zhì)中傳播的速度等于被測(cè)介質(zhì)的平均流速和聲波本身速度的幾何和的原理而設(shè)計(jì)的。它也是由測(cè)流速來(lái)反映流量大小的。超聲波流量計(jì)雖然在70年代才出現(xiàn)，但由于它可以制成非接觸型式，并可與超聲波水位計(jì)聯(lián)動(dòng)進(jìn)行開(kāi)口流量測(cè)量，對(duì)流體又不產(chǎn)生擾動(dòng)和阻力，所以很受歡。 </p> <p> 超聲波流量計(jì)按測(cè)量原理分可分為時(shí)差式和多普勒式 </p> <p> 利用時(shí)差式原理制造的時(shí)差式超聲流量計(jì)近年來(lái)得到廣泛的關(guān)注和使用，是目前企事業(yè)使用多的一種超聲波流量計(jì)。 </p> <p> 利用多普勒效應(yīng)制造的超聲多普勒流量計(jì)多用于測(cè)量介質(zhì)有一定的懸浮顆粒或氣泡介質(zhì)，使用有一定的局限性，但卻解決了時(shí)差式超聲波流量計(jì)只能測(cè)量單一清澈流體的問(wèn)題，也被認(rèn)為是非接觸測(cè)量雙相流的理想儀表。 </p><p> 渦街流量計(jì)(USF)特點(diǎn) </p> <p> （1）抗振性能差。外來(lái)振動(dòng)會(huì)使渦街流量計(jì)產(chǎn)生測(cè)量誤差，甚至不能正常工作。通道流體高流速?zèng)_擊會(huì)使渦街發(fā)生體的懸臂產(chǎn)生附加振動(dòng)，使測(cè)量精度降低。大管徑影響更為明顯。 </p> <p> （2）對(duì)測(cè)量臟污介質(zhì)適應(yīng)性差。渦街流量計(jì)的發(fā)生體極易被介質(zhì)臟污或被污物纏繞，改變幾何體尺寸，對(duì)測(cè)量精度造成極大影響。 </p> <p> <span style="font-size:12px;">（3）直管段要求高。**指出，渦街流量計(jì)直管段一定要保證前 40D 后

環(huán)形孔板適用于各種流體（氣體、蒸汽、液體）介質(zhì)，它除了具有標(biāo)準(zhǔn)孔板的結(jié)構(gòu)簡(jiǎn)單、牢固、安裝使用方便等特點(diǎn)以外，還具有以下優(yōu)點(diǎn)： </p> <p> 1、更適合測(cè)量飽和蒸汽、過(guò)熱蒸汽以及煤氣、冷卻水等臟污流體。 </p> <p> 2、更容易適應(yīng)高溫、高壓流體的流量測(cè)量。 </p> <p> 3、比圓缺孔板、偏心孔板工作更可靠，測(cè)量更精確。 </p> <p> 4、以較低的成本制成耐腐蝕型，測(cè)量腐蝕性流體的流量。 </p> <p> 5、由于本產(chǎn)品外部形狀簡(jiǎn)單，容易制成夾套保濕型在夾套內(nèi)通蒸汽，可以防止被測(cè)流體在測(cè)量管段內(nèi)凝結(jié)或粘附；通以冷卻液，可防止易汽化的液體在流經(jīng)測(cè)流板時(shí)形成汽液兩相流。 </p> <p> 6、采用均壓環(huán)結(jié)構(gòu)，減少了測(cè)量誤差來(lái)源引至差壓變送器的是在測(cè)流板上、下游處取壓管橫截面的靜壓平均值，減弱了上游局部阻力形成的速度分布畸變對(duì)精度的影響，實(shí)際精度更接近基本精度。 </p> <p> 7、要求較低的前后直管段 </p> <p> 8、采用一體型結(jié)構(gòu)形式，減少管線(xiàn)敷設(shè)。 </p> <p> 9、采用帶遠(yuǎn)傳膜盒的差壓變送器，可以測(cè)量諸如煤粉、渣油等臟污液體的流量。 </p> <p> 工作原理：環(huán)形孔板節(jié)流裝置和普通的標(biāo)準(zhǔn)孔板一樣，依據(jù)的基本原理是流體連續(xù)性方程和伯努利方程。把環(huán)形孔板安裝在圓管中，當(dāng)液體流經(jīng)節(jié)流裝置時(shí)，其上、下游側(cè)之間就會(huì)產(chǎn)生壓力差。 </p> <p>
