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。天津氣體渦輪流量計(jì)廠家哪家好孔板流量計(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 style="width:100%;text-align: center;"><img style="max-width:

渦街流量計(jì)工作狀態(tài)下的體積流量不受被測流體溫度、壓力、密度等熱工參數(shù)的影響，但液體或蒸汽的**終測量結(jié)果應(yīng)是質(zhì)量流量，對于氣體，**終測量結(jié)果應(yīng)是標(biāo)準(zhǔn)體積流量。質(zhì)量流量或標(biāo)準(zhǔn)體積流量都必須通過流體密度進(jìn)行換算，必須考慮流體工況變化引起的流體密度變化。 </p> <p> 造成流量測量誤差的因素主要有：管道流速不均造成的測量誤差；不能準(zhǔn)確確定流體工況變化時(shí)的介質(zhì)密度；將濕飽和蒸汽假設(shè)成干飽和蒸汽進(jìn)行測量。這些誤差如果不加以限制或消除，渦街流量計(jì) 的總測量誤差會很大。 </p><p> 超聲波流量計(jì)缺點(diǎn): </p> <p> （1）超聲波流量計(jì)的溫度測量范圍不高，一般只能測量溫度低于200℃的流體。 </p> <p> （2）抗干擾能力差。易受氣泡、結(jié)垢、泵及其它聲源混入的超聲雜音干擾、影響測量精度。 </p> <p> （3）直管段要求嚴(yán)格，為前**,后5D。否則離散性差，測量精度低。 </p> <p> （4）安裝的不確定性，會給流量測量帶來較大誤差。 </p> <p> （5）測量管道因結(jié)垢，會嚴(yán)重影響測量準(zhǔn)確度，帶來明顯的測量誤差，甚至在嚴(yán)重時(shí)儀表無流量顯示 </p> <p> （6）可靠性、精度等級不高（一般為1.5～2.5級左右），重復(fù)性差。 </p> <p> （7）使用壽命短（一般精度只能保證一年）。 </p> <p> <br />

超聲波流量計(jì)也是比較常見的流量計(jì)，它的安裝在所有流量計(jì)的安裝中是簡單便捷的，只要選擇一個(gè)合適的測量點(diǎn)，把測量點(diǎn)處的管道參數(shù)輸入到流量計(jì)中，然后把探頭固定在管道上即可。 <span style="font-size:12px;"> </span> </p> <p> 安裝要點(diǎn) </p> <p> 1、選擇充滿流體的材質(zhì)均勻質(zhì)密、易于超聲波傳輸?shù)墓芏?，如垂直管段或水平管段?</p> <p> 2、安裝距離應(yīng)選擇上游大于10倍直管徑、下游大于5倍直管徑以內(nèi)無任何閥門、彎頭、變徑等均勻的直管段，安裝點(diǎn)應(yīng)充分遠(yuǎn)離閥門、泵、高壓電和變頻器等干擾源。 </p> <p> 3、避免安裝在管道系統(tǒng)的比較高點(diǎn)或帶有自由出口的豎直管道上。 </p> <p> 4、對于開口或半滿管的管道，流量計(jì)應(yīng)安裝在U型管段處。 </p> <p> 渦街流量計(jì) 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。鹽城金屬轉(zhuǎn)子流量計(jì)廠家哪家好</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。浙江孔板流量計(jì)廠家直供</p><p
