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，江蘇孔板流量計(jì)廠。 </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)，江蘇孔板流量計(jì)廠，江蘇孔板流量計(jì)廠，其上、下游側(cè)之間就會(huì)產(chǎn)生壓力差。 </p> <p> 連接方式：法蘭連接和焊接連接。間接式質(zhì)量流量計(jì)是用密度計(jì)與容積流量直接相乘求得質(zhì)量流量的。江蘇孔板流量計(jì)廠</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="江蘇孔板流量計(jì)廠,流量計(jì)"

按流量計(jì)的結(jié)構(gòu)原理進(jìn)行分類。有容積式流量計(jì)、差壓式流量計(jì)、浮子流量計(jì)、渦輪流量計(jì)、電磁流量計(jì)、流體振蕩流量計(jì)中的渦街流量計(jì)、質(zhì)量流量計(jì)和插入式流量計(jì)。 </p> <p> 按測量對象劃分就有封閉管道和明渠兩大類;按測量目的又可分為總量測量和流量測量,其儀表分別稱作總量表和流量計(jì)?？偭勘頊y量一段時(shí)間內(nèi)流過管道的流量,是以短暫時(shí)間內(nèi)流過的總量除以該時(shí)間的商來表示,實(shí)際上流量計(jì)通常亦備有累積流量裝置,做總量表使用,而總量表亦備有流量發(fā)訊裝置。因此, 以嚴(yán)格意義來分流量計(jì)和總量表已無實(shí)際意義。江蘇孔板流量計(jì)廠標(biāo)準(zhǔn)孔板按常用取壓方式可分為角接取壓、法蘭取壓、徑距取壓三種類型。</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。 </p><p> 質(zhì)量流量計(jì)安裝要求1、安裝位置的選擇應(yīng)避免電磁干擾。傳感器、變送器的安裝位置以及電纜鋪設(shè)應(yīng)盡量遠(yuǎn)離易產(chǎn)生強(qiáng)電磁場的設(shè)備，如大功率馬達(dá)、變壓器設(shè)施、變頻設(shè)備等。2、質(zhì)量流量傳感器安裝應(yīng)使傳感器流向標(biāo)識與流體流向一致。并使箭頭指向與變送器內(nèi)部組態(tài)的流量方向一致。(注：質(zhì)量流量計(jì)可以雙向使用。如果安裝方向與實(shí)際流向相反，修改變送器內(nèi)的流向組態(tài)即可。)3、質(zhì)量流量計(jì)是根據(jù)測量管振動(dòng)原理測量的流量儀表，因此傳感器安裝時(shí)應(yīng)考慮在兩側(cè)的工藝管道近法蘭處(約2～10倍管徑處)做堅(jiān)固的支撐，避免儀表及相關(guān)管路產(chǎn)生震動(dòng)。若強(qiáng)烈的管道振動(dòng)不可避免時(shí)，建議用柔性管將管道系統(tǒng)與儀表傳感器隔離。4、因質(zhì)量流量計(jì)是依據(jù)科氏力原理工作的，為避免重力對計(jì)量精度的影響。質(zhì)量流量計(jì)的測量管無論是向上還是向下安裝，都要盡量使測量管與地平面保持垂直或水平。5、安裝時(shí)連接法蘭面應(yīng)相互平行，應(yīng)使兩個(gè)法蘭的中心位于同一軸線避免產(chǎn)生附加應(yīng)力。嚴(yán)禁用傳感器硬行拉直上、下游工藝管道，否則將影響測量甚至損壞傳感器。6、在傳感器的上、下游管道上，建議安裝截止閥及旁路以方便調(diào)零、日常維護(hù)及確保傳感器在不工作時(shí)亦可處于滿管狀態(tài)。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。</p><div
