當(dāng)超聲波在不均勻流體中傳送時(shí)，聲波會(huì)產(chǎn)生散射，智能靶式流量計(jì)聯(lián)系方式。流超聲流量計(jì)體與發(fā)送器間有相對(duì)運(yùn)動(dòng)時(shí)，發(fā)送的聲波信號(hào)和被流體散射后接收到的信號(hào)之間會(huì)產(chǎn)生多普勒頻移。多普勒頻移與流體流速成正比。被測(cè)流體的區(qū)域位于發(fā)射波束與接收到的散射波束的交叉之處，智能靶式流量計(jì)聯(lián)系方式，智能靶式流量計(jì)聯(lián)系方式。要求波束很窄，使兩波束的夾角θ不致受到波束寬度影響。也可只采用一個(gè)變換器既作為發(fā)送器又作為jieshouqi，這種方式稱為單通道式。在單通道多普勒血液流量計(jì)中，發(fā)送器間隔地發(fā)送聲脈沖信號(hào)，在兩個(gè)聲脈沖間隔的時(shí)間中，接收從血管壁和血管內(nèi)紅血球反射回來(lái)的聲脈沖信號(hào)。采用控制線路選擇給定距離處的紅血球反射信號(hào),通過(guò)比較后得到多普勒頻移,它與血液流速成正比。在已知血管橫截面時(shí)可得到血液流量。引導(dǎo)用戶接受并使用新技術(shù)流量計(jì)，如超聲波流量計(jì)、電磁流量計(jì)等，是生產(chǎn)商把市場(chǎng)做大做強(qiáng)的又一個(gè)挑戰(zhàn)。智能靶式流量計(jì)聯(lián)系方式</p><div

</p> <p> 2．對(duì)接地點(diǎn)要求: </p> <p> 為了使儀表可靠的工作，提高測(cè)量精度，不受外界寄生電勢(shì)的干擾/傳感器應(yīng)有良好的接地，接地電阻小于10.（若金屬管道接地良好時(shí)，無(wú)須專設(shè)接地裝置）。 </p> <p> 3.對(duì)安裝位置要求: </p> <p> 插入電磁流量計(jì)根據(jù)現(xiàn)場(chǎng)管路情況不一，不加裝球閥的流量計(jì)，應(yīng)在不帶壓倒管路上安裝（即不帶壓安裝可選擇不加裝球閥的流量計(jì)），在管道上開(kāi)孔直徑50，準(zhǔn)備把連接焊管焊接在管道的開(kāi)孔上；對(duì)于要求不斷流裝卸或不允許介質(zhì)溢出的場(chǎng)合，須加裝球閥，即選擇帶球閥結(jié)構(gòu)的插入式電磁流量計(jì)；在管道上開(kāi)孔直徑50，準(zhǔn)備把連接焊管焊接在管道的開(kāi)孔上。 </p><p> 大部分結(jié)構(gòu)浮子流量計(jì)只能用于自下向上垂直流的管道安裝。浮子流量計(jì)可用于較低雷諾數(shù)，選用粘度不敏感形狀的浮子，流通環(huán)隙處雷諾數(shù)只要大于40或500，雷諾數(shù)變化流量系數(shù)即保持常數(shù)，亦即流體粘度變化不影響流量系數(shù)。這數(shù)值遠(yuǎn)低于標(biāo)準(zhǔn)孔板等節(jié)流差壓式儀表比較低雷諾數(shù)104-105的要求。 </p> <p> 浮子流量計(jì)應(yīng)用局限于中小管徑，普通全流型浮子流量計(jì)不能用于大管徑，玻璃管浮子流量計(jì)比較大口徑100mm，金屬管浮子流量計(jì)為150mm，更大管徑只能用分流型儀表。 </p> <p> 使用流體和出廠標(biāo)定流體不同時(shí)，要作流量示值修正。液體用浮子流量計(jì)通常以水標(biāo)定，氣體用空氣標(biāo)定，如實(shí)際使用流體密度、粘度與之不同，流量要偏離原分度值，要作換算修正。在工業(yè)現(xiàn)場(chǎng)，測(cè)量流體流量的儀表統(tǒng)稱為流量計(jì)或流量表。是工業(yè)測(cè)量中重要的儀表之一。</p><div

傳播速度差法超聲流量計(jì)測(cè)量精度已優(yōu)于，有的多聲道超聲流量計(jì)的精度已高達(dá)士。但由于早期的超聲流量計(jì)自身一般不帶標(biāo)準(zhǔn)管道而工業(yè)上所用管路又十分復(fù)雜，使得超聲流量計(jì)的測(cè)量精度大打折扣;另外，由于工業(yè)現(xiàn)場(chǎng)特別是管路周圍環(huán)境的多樣性和復(fù)雜性，降低了超聲流量計(jì)的可靠性和穩(wěn)定性。因此，如何根據(jù)特定的環(huán)境安裝調(diào)試超聲流量計(jì)，就成了超聲流量測(cè)量領(lǐng)域的一個(gè)重要課題。符合規(guī)范的正確安裝，可以更好地體現(xiàn)超聲流量計(jì)的精度、可靠性和穩(wěn)定性方面的優(yōu)勢(shì)，降低儀表的日常維護(hù)工作。以前盛行的外夾裝式超聲流量計(jì)使用方便靈活，然而現(xiàn)場(chǎng)應(yīng)用的實(shí)際側(cè)量精度，常因工作琉忽，換能器安裝距離及流通面積等測(cè)量的誤差而造成梢度下降。不正確的安裝甚至?xí)沟脙x表完全不能工作;因此，安裝換能器對(duì)于測(cè)量是非常重要環(huán)節(jié):國(guó)外競(jìng)相開(kāi)發(fā)出經(jīng)實(shí)流核準(zhǔn)的高精度帶測(cè)量管段的中小口徑超聲流量計(jì)，且用雙聲道或多聲道以改善單聲道側(cè)量平均流速的不確定影響量，降低了迎流流速分布影響的敏感度，減少了前后置直管段長(zhǎng)度的影響，消除了現(xiàn)場(chǎng)安裝換能器位置的影響，使測(cè)量精度提高。金屬管浮子流量計(jì)無(wú)錐管破裂的風(fēng)險(xiǎn)。與玻璃管浮子流量計(jì)相比，使用溫度和壓力范圍寬。智能靶式流量計(jì)聯(lián)系方式</p><p
