style="text-indent:25px">孔板流量計(jì)的常見問題主要有以下幾類：被測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)，會隨著外界環(huán)境溫度的變化而發(fā)作復(fù)雜的改動，從而會影響到流量計(jì)的丈量精度。關(guān)于自然氣等密度會發(fā)作改動的介質(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。低密度氣體對某些丈量辦法的呈現(xiàn)艱難，此時(shí)就要改動已選定的丈量辦法，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)生臺階、偏心率；孔板上游端面的平度；環(huán)室尺寸產(chǎn)生臺階、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。</p><p style="text-indent:25px">質(zhì)量流量計(jì)由于流體的容積受溫度、壓力等參數(shù)的影響，用容積流量表示流量大小時(shí)需給出介質(zhì)的參數(shù)。在介質(zhì)參數(shù)不斷變化的情況下，往往難以達(dá)到這一要求，而造成儀表顯示值失真。因此，質(zhì)量流量計(jì)就得到的應(yīng)用和重視。質(zhì)量流量計(jì)分直接式和間接式兩種。直接式質(zhì)量流量計(jì)利用與質(zhì)量流量直接有關(guān)的原理進(jìn)行測量，目前常用的有量熱式、角動量式、振動陀螺式、馬格努斯效應(yīng)式和科里奧利力式等質(zhì)量流量計(jì)。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?？装辶髁坑?jì)應(yīng)用范圍廣，全部單相流皆可測量，部分混相流亦可應(yīng)用。</p><div

V錐流量計(jì)特點(diǎn)V錐流量計(jì)是從2000年左右才在中國國內(nèi)出現(xiàn)的流量計(jì)。其工作原理和孔板流量計(jì)相同。介質(zhì)通過V錐時(shí),由于阻流件V錐的存在,使得流體的流過面積發(fā)生變化,流速發(fā)生變化,根據(jù)伯努利方程,流速變化引起了壓力的變化,該壓力的變化與流速之間有一定的關(guān)系。通過測量該壓力差達(dá)到測量流量的目的。雖然與孔板原理一樣,但是本質(zhì)的區(qū)別在于孔板為中心收縮型節(jié)流裝置,而V錐為邊壁收縮型節(jié)流裝置。眾所周知,測量范圍窄是制約孔板使用的主要原因。測量范圍窄的主要原因是:孔板的流量系數(shù)隨雷諾數(shù)的變化而變化較大,孔板的突然節(jié)流導(dǎo)致孔板后發(fā)生比較大的漩渦,該漩渦的存在直接導(dǎo)致信號噪聲比較大,從而限制了它的測量范圍。而V錐流量計(jì)克服了以上缺點(diǎn)。 </p> <p> <br /> </p> <p> <br /> 流量計(jì)可以水平和垂直安裝，但是應(yīng)該確保避免沉積物和氣泡對測量電極的影響，電極軸向保持水平為好。蘇州氣體渦輪流量計(jì)哪家比較好</p><p

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，從而使流速增加，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)可以通過測量壓差來衡量流體流量的大小。這種測量方法是以能量守衡定律和流動連續(xù)性定律為基準(zhǔn)的。智能節(jié)流裝置（孔板流量計(jì)）是集流量、溫度、壓力檢測功能于一體，并能進(jìn)行溫度、壓力自動補(bǔ)償?shù)男乱淮髁坑?jì)，該孔板流量計(jì)采用先進(jìn)的微機(jī)技術(shù)與微功耗新技術(shù)，功能強(qiáng)，結(jié)構(gòu)緊湊，操作簡單，使用方便?！装辶髁坑?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?！装逵?jì)算采用國際標(biāo)準(zhǔn)與加工▲孔板流量計(jì)應(yīng)用范圍廣，全部單相流皆可測量，部分混相流亦可應(yīng)用。▲標(biāo)準(zhǔn)型節(jié)流裝置無須實(shí)流校準(zhǔn)，即可投用?！惑w型孔板流量計(jì)安裝更簡單，無須引壓管，可直接接差壓變送器和壓力變送器。
