主要安裝要求是對于直管段的要求及管道振動要求，渦街流量傳感器的上游側(cè)和下游側(cè)應(yīng)有較長的直管段;管道不能有振動，如有振動，則需對流量計(jì)兩側(cè)加固定裝置。 </p> <p> 對于渦街流量計(jì)來說，測量氣體流量時，若被測氣體含有少量的液體，流量計(jì)應(yīng)安裝在管線的較高處。測量液體時，若被測液體中含有少量的氣體，流量計(jì)應(yīng)安裝在管線的較低處。測壓孔和測溫孔：需要測壓時,須將測壓孔設(shè)置在流量計(jì)下游2~7D的地方。需要測溫時,將溫度傳感器設(shè)置在離測壓點(diǎn)下游的1~2D之間處。 </p> <p> 管道支撐：盡量將流量計(jì)安裝在振動加速度小于20m/s2的地方。當(dāng)管道振動過強(qiáng)時,應(yīng)對管道安裝加固支撐，重慶液體渦輪流量計(jì)供貨商。封墊片：切不可將密封墊片突出到管道中，重慶液體渦輪流量計(jì)供貨商,否則將導(dǎo)致無法接受的誤差，重慶液體渦輪流量計(jì)供貨商。污水流量計(jì)結(jié)構(gòu)簡單、牢固可靠、使用壽命長。重慶液體渦輪流量計(jì)供貨商</p><div

1．孔板流量計(jì)安裝前應(yīng)仔細(xì)核對標(biāo)準(zhǔn)孔板的編號、位號、規(guī)格是否與管道情況、流量范圍等參數(shù)相符。在取壓口附近標(biāo)有“+”的一端應(yīng)與流體上游管段聯(lián)接，標(biāo)有“—”的一端應(yīng)與流體下游管段聯(lián)接。 </p> <p> 2．對于新設(shè)管路系統(tǒng)，必須先經(jīng)掃線后再安裝標(biāo)準(zhǔn)孔板，以防管內(nèi)雜物堵塞或損傷標(biāo)準(zhǔn)孔板。 </p> <p> 3．標(biāo)準(zhǔn)孔板的中心線應(yīng)當(dāng)與管道中心線同軸。 </p> <p> 孔板流量計(jì)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。常州金屬轉(zhuǎn)子流量計(jì)批發(fā)價格智能電磁流量計(jì)因?yàn)榻Y(jié)構(gòu)簡單，流量計(jì)外殼、被測流體和管道連接法蘭三者之間應(yīng)做等電位連接，并應(yīng)接地；</p><div

流量測量的發(fā)展可追溯到古代的水利工程和城市供水系統(tǒng)。古羅馬凱撒時代已采用孔板測量居民的飲用水水量。公元**00年左右古埃及用堰法測量尼羅河的流量。我國的都江堰水利工程應(yīng)用寶瓶口的水位觀測水量大小等等。17世紀(jì)托里拆利奠定差壓式流量計(jì)的理論基礎(chǔ)，這是流量測量的里程碑。自那以后，18、19世紀(jì)流量測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。重慶液體渦輪流量計(jì)供貨商</p><p
