<p> 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。 </p> <p> 浮子流量計(jì)是僅次于差壓式流量計(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。 </p> <p> <span style="font-size:12px;">80 年代中期,日本、西歐、美國(guó)的銷售金額占流量?jī)x表的 15%~20%。我國(guó)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)。</span> </p> <p> 特點(diǎn): </p> <p>

為了智能電磁流量計(jì)能夠很好地正常使用，智能電磁流量計(jì)傳感器接地一定要安裝好。智能電磁流量計(jì)傳感器接地時(shí)，應(yīng)注意以下幾點(diǎn)： </p> <p> 1、傳感器、轉(zhuǎn)換器的接地在現(xiàn)場(chǎng)，去二次儀表的屏蔽層在控制室一側(cè)接地，切勿多端接地，以免因電位不同而引入干擾。 </p> <p> 2、傳感器安裝在金屬管道上，可將傳感器的接地導(dǎo)線按制造廠的要求連接在管道法蘭上，形成可靠的接地回路儀表的接地點(diǎn)應(yīng)是一個(gè)**的接地點(diǎn)，不可以共用其他電氣設(shè)備的接地。 </p> <p> 3、傳感器的測(cè)量管、外殼、屏蔽線、轉(zhuǎn)換器及二次儀表都要接地。 </p> <p> 4、傳感器、轉(zhuǎn)換器應(yīng)單獨(dú)接地，不要連在電動(dòng)機(jī)、工藝管道上，接地電阻應(yīng)小于10歐姆。 </p><p> 熱式質(zhì)量流量計(jì)（恒溫差TMF） </p> <p> 優(yōu)點(diǎn): </p> <p> （1）球閥安裝，安裝拆卸方便。并可以帶壓安裝。 </p> <p> （2）基于金氏定律，直接測(cè)量質(zhì)量流量。測(cè)量值不受壓力和溫度影響。 </p> <p> （3）響應(yīng)迅速。 </p> <p> （4）量程范圍大，管道式安裝小可以測(cè)量8.8mm管道的流量，比較大可以測(cè)到30’’ </p> <p> （5）插入式類型的流量計(jì)，一支流量計(jì)可以用于測(cè)量多種管徑。 </p> <p> 缺點(diǎn): </p> <p> （1）精度不及其他類型流量計(jì)，一般為3％。 </p> <p> （2）適用范圍窄，只能用于測(cè)量干燥的非性的氣體，如壓縮空氣、氮?dú)狻鍤饧捌渌行詺怏w。質(zhì)量流量計(jì)可以雙向使用。如果安裝方向與實(shí)際流向相反，修改變送器內(nèi)的流向組態(tài)即可。</p><div style="width:100%;text-align:

流量測(cè)量的發(fā)展可追溯到古代的水利工程和城市供水系統(tǒng)。古羅馬凱撒時(shí)代已采用孔板測(cè)量居民的飲用水水量。公元**00年左右古埃及用堰法測(cè)量尼羅河的流量。我國(guó)的都江堰水利工程應(yīng)用寶瓶口的水位觀測(cè)水量大小等等。17世紀(jì)托里拆利奠定差壓式流量計(jì)的理論基礎(chǔ)，這是流量測(cè)量的里程碑。自那以后，18、19世紀(jì)流量測(cè)量的許多類型儀表的雛形開始形成，如堰、示蹤法、皮托管、文丘里管、容積、渦輪及靶式流量計(jì)等。孔板流量計(jì)前后產(chǎn)生一個(gè)靜壓力差,該壓力差與流量存在著一定的函數(shù)關(guān)系,流量越大,壓力差就越大；安徽長(zhǎng)頸噴嘴流量計(jì)廠家</p><p
