style="text-indent:25px">浮子流量計(jì)浮子流量計(jì),又稱轉(zhuǎn)子流量計(jì),是變面積式流量計(jì)的一種,在一根由下向上擴(kuò)大的垂直錐管中,圓形橫截面的浮子的重力是由液體動(dòng)力承受的,從而使浮子可以在錐管內(nèi)自由地上升和下降。浮子流量計(jì)是*次于差壓式流量計(jì)應(yīng)用范圍寬廣的一類流量計(jì),特別在小、微流量方面有舉足輕重的作用。80年代中期,日本、西歐、美國的銷售金額占流量儀表的15%~20%。我國產(chǎn)量1990年估計(jì)在12~14萬臺(tái),其中95%以上為玻璃錐管浮子流量計(jì)。特點(diǎn):(1)玻璃錐管浮子流量計(jì)結(jié)構(gòu)簡單,使用方便,缺點(diǎn)是耐壓力低,有玻璃管易碎的較大風(fēng)險(xiǎn);(2)適用于小管徑和低流速;(3)壓力損失較低。浙江金屬轉(zhuǎn)子流量計(jì)供貨商孔板流量計(jì)使流速增加，靜壓力低，于是在節(jié)流件前后便產(chǎn)生了壓力降，即壓差；</p><div

孔板流量計(jì)使流速增加，靜壓力低，于是在節(jié)流件前后便產(chǎn)生了壓力降，即壓差，介質(zhì)流動(dòng)的流量越大，在節(jié)流件前后產(chǎn)生的壓差就越大，所以孔板流量計(jì)可以通過測(cè)量壓差來衡量流體流量的大小。這種測(cè)量方法是以能量守衡定律和流動(dòng)連續(xù)性定律為基準(zhǔn)的?？装辶髁坑?jì)可測(cè)量管道中各種流體的流量，可測(cè)量的介質(zhì)有液體、氣體、蒸汽，被廣泛應(yīng)用于石油、化工、冶金、輕工、煤礦等工業(yè)部門。測(cè)量原理：充滿管道的流體，當(dāng)它們流經(jīng)管道內(nèi)的節(jié)流裝置時(shí)，流束將在節(jié)流裝置的節(jié)流件處形成局部收縮. </p> <p> <br /> </p> <p> <br /> </p><p style="text-indent:25px">孔板流量計(jì)的常見問題主要有以下幾類：被測(cè)流體特性的影響比方在用孔板流量計(jì)丈量自然氣流量的時(shí)分，思索到自然氣自身的性質(zhì)，會(huì)隨著外界環(huán)境溫度的變化而發(fā)作復(fù)雜的改動(dòng)，從而會(huì)影響到流量計(jì)的丈量精度。關(guān)于自然氣等密度會(huì)發(fā)作改動(dòng)的介質(zhì)的丈量，必需首先肯定一個(gè)穩(wěn)定的工作溫度和正常的壓力。盡量減小外界溫度變化所帶來的壓力和溫度隨之發(fā)作的變化，大水平減小密度變化和緊縮系數(shù)變化，從而保證丈量的精確度。低密度氣體對(duì)某些丈量辦法的呈現(xiàn)艱難，此時(shí)就要改動(dòng)已選定的丈量辦法，或者作溫度，并及時(shí)停止壓力修正，以保證丈量精確精確度。儀表性能的影響孔板流量計(jì)自身可能惹起誤差的緣由主要有：孔板入口直角銳利度；管徑尺寸與原方案不符；孔板厚度存在誤差；節(jié)流件附件產(chǎn)生臺(tái)階、偏心率；孔板上游端面的平度；環(huán)室尺寸產(chǎn)生臺(tái)階、偏心率；取壓的位置；焊接、焊縫能否突出；取壓孔加工不標(biāo)準(zhǔn)或呈現(xiàn)梗塞；節(jié)流件的不同軸度等等。這些要素都有可能影響孔板的反復(fù)性，反復(fù)性是由儀器自身的結(jié)構(gòu)原理與制造質(zhì)量所決議的，它的過程控制在實(shí)踐應(yīng)用中是很重要的指標(biāo)。而準(zhǔn)確度除了取決于反復(fù)性之外，還與量值標(biāo)定系統(tǒng)有關(guān)系。在實(shí)踐應(yīng)用中，儀表性能的反復(fù)性被許多要素干擾。超聲波流量計(jì)是一種非接觸式測(cè)量儀表，可用來測(cè)量不易接觸、不易觀察的流體流量和大管徑流量。</p><div

售價(jià)較高同種規(guī)格的V錐流量計(jì)的價(jià)格要高于孔板流量計(jì),但低于可更換孔板流量計(jì)。由于V錐的用料多、加工工藝復(fù)雜、標(biāo)定費(fèi)用高,使得其售價(jià)較高。但是在考慮流量計(jì)時(shí),初次購買價(jià)及安裝費(fèi)用、儀表的可靠性、長期維護(hù)費(fèi)用、長久壓力損失等綜合因素的總評(píng)才是選取流量計(jì)的依據(jù),只有綜合考慮并權(quán)衡了以上這些重要因素,才能做到合理選型。如前所述,V錐流量計(jì)除了在初次購買費(fèi)用上高于孔板流量計(jì)外,其他的費(fèi)用應(yīng)該與孔板流量計(jì)持平或低于孔板流量計(jì)。尤其是在補(bǔ)償壓力損失所需要的耗能方面,V錐流量計(jì)遠(yuǎn)遠(yuǎn)優(yōu)于孔板流量計(jì)。所以從長遠(yuǎn)考慮,使用V錐流量計(jì)的綜合費(fèi)用要低于孔板流量計(jì)。使用可更換孔板的目的就是為了提高孔板的量程比。但是其價(jià)格昂貴。如果給V錐流量計(jì)配兩臺(tái)不同量程的變送器（壓力變送器、差壓變送器）,那么其量程比的擴(kuò)展要遠(yuǎn)大于可更換孔板流量計(jì),而其價(jià)格要遠(yuǎn)低于可更換孔板。3差壓較低由于V錐流量計(jì)的流出系數(shù)要大于孔板流量計(jì)的流出系數(shù),使得相同流量時(shí)孔板的差壓值要高于V錐的差壓值?？装辶髁坑?jì)的變送器一般都是用中差壓表,V錐流量計(jì)一般用低差壓表。
