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，液體渦旋流量計(jì)廠家，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，液體渦旋流量計(jì)廠家。透明錐形管材料用得多的是玻璃，液體渦旋流量計(jì)廠家，無(wú)導(dǎo)向結(jié)構(gòu)儀表測(cè)量氣體時(shí)操作不慎，玻璃管易被擊碎。液體渦旋流量計(jì)廠家</p><div

2、測(cè)量管內(nèi)無(wú)阻礙流動(dòng)部件，無(wú)壓損，直管段要求較低。對(duì)漿液測(cè)量有獨(dú)特的適應(yīng)性； </p> <p> 3、合理選擇傳感器襯里和電極材料，即具有良好的耐腐蝕和耐磨損性； </p> <p> 4、轉(zhuǎn)換器采用新穎勵(lì)磁方式，功耗低、零點(diǎn)穩(wěn)定、精確度高。流量范圍度可達(dá)150：1； </p> <p> 5、轉(zhuǎn)換器可與傳感器組成一體型或分離型； </p> <p> 6、轉(zhuǎn)換器采用16位高性能微處理器，2x16LCD顯示，參數(shù)設(shè)定方便，編程可靠； </p> <p> 7、流量計(jì)為雙向測(cè)量系統(tǒng)，內(nèi)裝三個(gè)積算器：正向總量、反向總量及差值總量；可顯示正、反流量，并具有多種輸出：電流、脈沖、數(shù)字通訊、HART； </p> <p> 8、轉(zhuǎn)換器采用表面安裝技術(shù)(SMT)，具有自檢和自診斷功能； </p> <p> 9、測(cè)量精度不受流體密度、粘度、溫度、壓力和電導(dǎo)率變化的影響，傳感器感應(yīng)電壓信號(hào)與平均流速呈線性關(guān)系，因此測(cè)量精度高。 </p> <p> 10、測(cè)量管道內(nèi)無(wú)阻流件，因此沒有附加的壓力損失；測(cè)量管道內(nèi)無(wú)可動(dòng)部件，因此傳感器壽命極長(zhǎng)。 </p> <p> 11、由于感應(yīng)電壓信號(hào)是在整個(gè)充滿磁場(chǎng)的空間中形成的，是管道載面上的平均值，因此傳感器所需的直管段較短，長(zhǎng)度為5倍的管道直徑。 </p> <p> <br /> 液體渦旋流量計(jì)廠家槽式流量計(jì)發(fā)展的同時(shí)，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。</p><div

在被測(cè)流體溫度過高或?qū)﹄姌O有強(qiáng)烈腐蝕作用等情況下，可采用感應(yīng)式電磁流量計(jì)。A、B為匝數(shù)相等的兩個(gè)交流激磁繞組，繞組之間是串聯(lián)的，但各自的電流方向相反。當(dāng)流體靜止時(shí)，通過感應(yīng)線圈C的合成磁通為零，故線圈中沒有感生的交變電動(dòng)勢(shì)。流體流動(dòng)時(shí)感應(yīng)線圈中就產(chǎn)生交變電動(dòng)勢(shì)，其大小與流速成正比?；谶@一原理，還有很多改型方案。例如用一個(gè)激磁繞組，而在它的對(duì)稱的兩側(cè)各安置一方向相反的感應(yīng)線圈并串聯(lián)起來(lái)流體流動(dòng)時(shí)，磁力線向流動(dòng)方向移動(dòng)，使兩邊感應(yīng)線圈中的產(chǎn)生電動(dòng)勢(shì)不為零，由此可間接表示出流量的大小。電磁流量計(jì)的管道內(nèi)沒有其他部件，所以除用于測(cè)量導(dǎo)電流體的流量外，還可用于測(cè)量各種粘度的不導(dǎo)電液體（其中加入易電離物質(zhì)）的流量。在核能工業(yè)中經(jīng)常使用電磁流量計(jì)。液體渦旋流量計(jì)廠家</p></p><br
