</p> <p> 優(yōu)點(diǎn): </p> <p> (1)應(yīng)用多的孔板式流量計(jì)結(jié)構(gòu)牢固,性能穩(wěn)定可靠,使用壽命長; </p> <p> (2)應(yīng)用范圍,至今尚無任何一類流量計(jì)可與之相比擬; </p> <p> (3)檢測件與變送器、顯示儀表分別由不同廠家生產(chǎn),便于規(guī)模經(jīng)濟(jì)生產(chǎn)。 </p> <p> 缺點(diǎn): </p> <p> (1)測量精度普遍偏低;<span style="display:none;"></span> </p> <p> (2)范圍度窄,一般* 3:1~4:1; </p> <p> (3)現(xiàn)場安裝條件要求高; </p> <p> (4)壓損大(指孔板、噴嘴等)。上海電磁流量計(jì)廠流量計(jì)有渦輪流量計(jì)、渦街流量計(jì)、電磁流量計(jì)、多普勒超聲波流量計(jì)、熱線測速流量計(jì)；</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

電磁流量計(jì)的應(yīng)用有一定局限性，它只能測量導(dǎo)電介質(zhì)的液體流量，不能測量非導(dǎo)電介質(zhì)的流量，例如氣體和水處理較好的供熱用水。另外在高溫條件下其襯里需考慮。 </p> <p> 電磁流量計(jì)是通過測量導(dǎo)電液體的速度確定工作狀態(tài)下的體積流量。按照計(jì)量要求，對于液態(tài)介質(zhì)，應(yīng)測量質(zhì)量流量，測量介質(zhì)流量應(yīng)涉及到流體的密度，不同流體介質(zhì)具有不同的密度，而且隨溫度變化。如果電磁流量計(jì)轉(zhuǎn)換器不考慮流體密度，*給出常溫狀態(tài)下的體積流量是不合適的。 </p><p> 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。孔板流量計(jì)前后產(chǎn)生一個(gè)靜壓力差,該壓力差與流量存在著一定的函數(shù)關(guān)系,流量越大,壓力差就越大；</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

電磁流量計(jì)有一系列優(yōu)良特性,可以解決其它流量計(jì)不易應(yīng)用的問題,如臟污流、腐蝕流的測量。變送器的測量信號為很小的毫伏級電勢信號，除流量信號外，還夾雜一些與流量無關(guān)的信號，如同相電壓、正交電壓及共模電壓等。為了準(zhǔn)確測量流量，必須消除各種干擾信號，有效放大流量信號。應(yīng)該提高流量轉(zhuǎn)換器的性能，比較好采用微處理機(jī)型的轉(zhuǎn)換器，用它來控制勵(lì)磁電壓，按被測流體性質(zhì)選擇勵(lì)磁方式和頻率，可以排除同相干擾和正交干擾。但改進(jìn)的儀表結(jié)構(gòu)復(fù)雜，成本較高。福建孔板流量計(jì)找哪家</p><p
