style="text-indent:25px">超聲流量計是通過檢測流體流動對超聲束(或超聲脈沖)的作用以測量流量的儀表。超聲流量計主要由安裝在測量管道上的超聲換能器(或由換能器和測量管組成的超聲流量傳感器)和轉(zhuǎn)換器組成。超聲流量計和電磁流量計一樣，因儀表流通通道未設(shè)置任何阻礙件，均屬無阻礙流量計，是適于解決流量測量困難問題的一類流量計，特別在大口徑流量測量方面有較突出的優(yōu)點，它是發(fā)展迅速的一類流量計之一。根據(jù)對信號檢測的原理，超聲流量計可分為傳播速度差法(直接時差法、時差法、相位差法和頻差法)，甘肅浮子流量計、波束偏移法、多普勒法，甘肅浮子流量計、互相關(guān)法、空間濾法及噪聲法等。槽式流量計發(fā)展的同時，甘肅浮子流量計，美籍匈牙利人卡門正在研究渦街理論，1911年到1912年，他提出了卡門渦街新理論。甘肅浮子流量計</p><div

插入式電磁流量計安裝步驟：1.插入式電磁流量計要求用戶管道應(yīng)為水平設(shè)置，傳感器前至少有5DN、其后至少應(yīng)有3DN的直管段。流量調(diào)節(jié)閥應(yīng)位于傳感器下游3DN以外。管道應(yīng)明顯振動，管道內(nèi)壁應(yīng)無明顯凹凸不平。2.先在管道測量點處正上方開一個Ф60-62mm的孔，要求圓孔四周邊緣光潔，無毛刺和氣割瘤疤等。3.將安裝件從傳感器上擰下來并可靠地焊接在上述開孔處，要求：使安裝件下端與管道內(nèi)面齊平并且保證不漏。4.松開傳感器的3個鎖緊螺釘將檢測桿及檢測頭整體抽出待后面安裝。（注意：用戶不得打開檢測頭與插入桿的連接）。5.在安裝件的上端螺紋處纏以麻絲鉛油或纏以四氟生膠帶后將球閥連同密封劑鎖緊機構(gòu)擰緊在上面。6.將檢測桿從上方慢慢地再插入進(jìn)去，將鎖緊螺母稍稍加力擰緊，壓下插入桿測量L2與記錄L2尺寸相同，安裝就完成了。甘肅浮子流量計透明錐形管4用得普遍是由硼硅玻璃制成，習(xí)慣簡稱玻璃管浮子流量計。</p><div

渦街流量計安裝對直管段的要求：正確地選擇安裝點和正確安裝流量計都是非常重要的環(huán)節(jié)，若安裝環(huán)節(jié)失誤輕者影響測量精度，重者會影響流量計的使用壽命，甚至?xí)p壞流量計。渦街流量計安裝對直管段的要求是非常重要的。它的詳細(xì)要求如***量計對安裝點上的上下游直管段一定的要求，否則會影響測量精度。若流量計安裝點上的上游有漸縮管，流量計上游應(yīng)有不小于15D(D為管道直徑)的等徑直管段，下游應(yīng)有不小于5D的等徑直管段。若流量計安裝點上的上游有漸擴管，流量計上游應(yīng)有不小于18D(D為管道直徑)的等徑直管段，下游應(yīng)有不小于5D的等徑直管段若流量計安裝點上游有90°彎頭或下行接頭，流量計上游應(yīng)有不小于**的等徑直管段，下游應(yīng)有不小于5D的等徑直管段。若流量計安裝點上游在同一平面上有90°彎頭，流量計上游應(yīng)有不小于25D的等徑直管段，下游應(yīng)有不小于5D的等徑直管段。流量調(diào)節(jié)閥或壓力調(diào)節(jié)閥盡量安裝在流量計下游5D以遠(yuǎn)處，若必須安裝在流量計的上游，流量計上游應(yīng)有不小于25D的等徑直管段，下游應(yīng)有不小于5D的等徑直管段。流量計上游若有活塞式或柱塞式泵，活塞式或羅茨式風(fēng)機、壓縮機，流量計上游應(yīng)有不小于25D的等徑直管段，下游應(yīng)有不小于5D的等徑直管段。 </p><p> 方面的考慮因素如下： </p> <p> 1．儀表性能方面：精確度、重復(fù)性、線性度、范圍度、壓力損失、上下限流量、信號輸出特性、響應(yīng)時間等； </p> <p> 2．流體特性方面：流體壓力、溫度、密度、粘度、潤滑性、化學(xué)性質(zhì)、磨損、腐蝕、結(jié)垢、臟污、氣體壓縮系數(shù)、等熵指數(shù)、比熱容、電導(dǎo)率、聲速、混相流、脈動流等； </p> <p> 3．環(huán)境條件方面：環(huán)境溫度、濕度、安全性、電磁干擾等；浮子流量計 </p> <p> 4．經(jīng)濟因素方面：購置費、安裝費、維修費、校驗費、使用壽命、運行費（能耗）、備品備件等。 </p> <p> <br /> 金屬管錐形管可用于較高的介質(zhì)溫度和壓力，且無玻璃管浮子流量計錐管被擊碎的潛在危險。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

差壓式孔板流量計是一款流量測量儀表，主要應(yīng)用于液體、氣體流量測量，像蒸汽流量測量就是一個典型的測量工況，蒸汽在流量測量的過程中，由于自身溫度較高，測量難度大一般的流量計都無法勝任，而差壓式孔板流量計就可以有效的解決。差壓式孔板流量計的應(yīng)用領(lǐng)域非常廣，測量精度可達(dá)±0.5%，溫度可達(dá)700度，并且量程比為10：1，主要在氣體、蒸汽、液體的流量測量領(lǐng)域應(yīng)用較多，差壓式孔板流量計還有一個優(yōu)勢就是安裝方便，并且也不需要維護(hù)。流量分度直接刻在錐管4外壁上，也有在錐管旁另裝分度標(biāo)尺。甘肅浮子流量計</p><p

電磁流量計就顯示方式分為：分體型電磁流量計，一體型電磁流量計。系列公稱通徑DN15～DN3000。分體型電磁流量計是一種根據(jù)法拉第電磁感應(yīng)定律來測量管內(nèi)導(dǎo)電介質(zhì)體積流量的感應(yīng)式儀表，采用單片機嵌入式技術(shù)，實現(xiàn)數(shù)字勵磁，同時在電磁流量計上采用CAN現(xiàn)場總線，屬國內(nèi)**，技術(shù)達(dá)到國內(nèi)**水平。分體型電磁流量計在滿足現(xiàn)場顯示的同時，還可以輸出4～20mA電流信號供記錄、調(diào)節(jié)和控制用，現(xiàn)已廣地應(yīng)用于化工、環(huán)保、冶金、醫(yī)藥、造紙、給排水等工業(yè)技術(shù)和管理部門。分體型電磁流量計除可測量一般導(dǎo)電液體的流量外，還可測量液固兩相流，高粘度液流及鹽類、強酸、強堿液體的體積流量。甘肅浮子流量計</p><p
