差壓式流量計(jì)應(yīng)用范圍特別,在封閉管道的流量測量中各種對象都有應(yīng)用,如流體方面:單相、混相、潔凈、臟污、粘性流等;工作狀態(tài)方面:常壓、高壓、真空、常溫、高溫、低溫等;管徑方面:從幾 mm 到幾 m;流動條件方面:亞音速、音速、脈動流等。它在各工業(yè)部門的用量約占流量計(jì)全部用量的 1/4~1/3。 </p> <p> 孔板以內(nèi)孔銳角線來保證精度，因此對腐蝕、磨損、結(jié)垢、臟污敏感，長期使用精度難以保證，需每年拆下強(qiáng)檢一次。采用法蘭連接，易產(chǎn)生跑、冒、滴、漏問題，湖北長頸噴嘴流量計(jì)源頭直供廠家，增加了維護(hù)工作量。 </p> <p> 工業(yè)發(fā)達(dá)國家近年 PD流量計(jì)(不包括家用煤氣表和家用水表)的銷售金額占流量儀表的

固定式超聲波流量計(jì)用于安裝在某一固定方位，對某一特定管道內(nèi)流體的流量進(jìn)行長時(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)動性，首要用于對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(shí)調(diào)出運(yùn)用。

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、更適合測量飽和蒸汽、過熱蒸汽以及煤氣、冷卻水等臟污流體。 </p> <p> 2、更容易適應(yīng)高溫、高壓流體的流量測量。 </p> <p> 3、比圓缺孔板、偏心孔板工作更可靠，測量更精確。 </p> <p> 4、以較低的成本制成耐腐蝕型，測量腐蝕性流體的流量。 </p> <p> 5、由于本產(chǎn)品外部形狀簡單，容易制成夾套保濕型在夾套內(nèi)通蒸汽，可以防止被測流體在測量管段內(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)，減少了測量誤差來源引至差壓變送器的是在測流板上、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，減少管線敷設(shè)。 </p> <p> 9、采用帶遠(yuǎn)傳膜盒的差壓變送器，可以測量諸如煤粉、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)之間就會產(chǎn)生壓力差。 </p> <p> 連接方式：法蘭連接和焊接連接。 </p><p> 電磁流量計(jì)的安裝與調(diào)試比其它流量計(jì)復(fù)雜，且要求更嚴(yán)格。變送器和轉(zhuǎn)換器必須配套使用，兩者之間不能用兩種不同型號的儀表配用。在安裝變送器時(shí)，從安裝地點(diǎn)的選擇到具體的安裝調(diào)試，必須嚴(yán)格按照產(chǎn)品說明書要求進(jìn)行。安裝地點(diǎn)不能有振動，不能有強(qiáng)磁場。在安裝時(shí)必須使變送器和管道有良好的接觸及良好的接地。變送器的電位與被測流體等電位。在使用時(shí)，必須排盡測量管中存留的氣體，否則會造成較大的測量誤差。 </p> <p> 電磁流量計(jì)用來測量帶有污垢的粘性液體時(shí)，粘性物或沉淀物附著在測量管內(nèi)壁或電極上，使變送器輸出電勢變化，帶來測量誤差，電極上污垢物達(dá)到一定厚度，可能導(dǎo)致儀表無法測量。孔板流量計(jì)節(jié)流裝置結(jié)構(gòu)易于復(fù)制，簡單、牢固，性能穩(wěn)定可靠，使用期限長，價(jià)格低廉。</p><div

工作原理：在一定的流量范圍內(nèi)，渦輪的轉(zhuǎn)速與流體的流速成正比。流體流動帶動渦輪轉(zhuǎn)動，渦輪的轉(zhuǎn)速轉(zhuǎn)換成電脈沖，用二次表顯示出數(shù)據(jù)，反應(yīng)流體流速。 </p> <p>
