ZNLUCB型插入式 渦街流量計(jì) 主要用于各種行業(yè)工業(yè)管道中大口徑氣體、液體、蒸汽介質(zhì)流體的流量測(cè)量,插入式 渦街流量計(jì) 特點(diǎn)是壓力損失小,量程范圍大,精度高,在測(cè)量工況體積流量時(shí)幾乎不受流體密度、壓力、溫度、粘度等參數(shù)的影響。無(wú)可動(dòng)機(jī)械零件,因此可靠性高,維護(hù)量小。儀表參數(shù)能長(zhǎng)期穩(wěn)定。插入式 渦街流量計(jì) 采用壓電應(yīng)力式傳感器,可靠性高,可在-20℃~+250℃的工作溫度范圍內(nèi)工作。有模擬標(biāo)準(zhǔn)信號(hào),也有數(shù)字脈沖信號(hào)輸出,容易與計(jì)算機(jī)等數(shù)字系統(tǒng)配套使用,是一種比較先進(jìn)、理想的流量?jī)x表。。
     ZNLUCB 型插入式 渦街流量計(jì) 防爆型,符合GB3836-83《爆炸性環(huán)境用防爆電氣設(shè)備》的有關(guān)規(guī)定,防爆標(biāo)志為ExdIIBT6。
工作原理
    按國(guó)際標(biāo)準(zhǔn)化組織IS07145(在環(huán)形截面封閉管道中的流體流量測(cè)定—在截面一點(diǎn)的速度測(cè)量法),采用埋入壓電晶體的渦街測(cè)速探頭,插入大口徑工業(yè)管道內(nèi),將卡門旋渦頻率轉(zhuǎn)換為與流量成正比的電流或電壓脈沖信號(hào)或4~20mADC電流信號(hào)。
儀表特點(diǎn)     
1、 可測(cè)量蒸汽,氣體,液體的體積流量和質(zhì)量流量;
2、無(wú)機(jī)械運(yùn)動(dòng)部件,測(cè)量精度高,結(jié)構(gòu)緊湊維護(hù)方便;
3、壓力損失小,量程范圍寬;范圍度達(dá)1:25;
4、采用消擾電路和抗振傳感頭;
5、采用消擾電路和抗振傳感頭,使儀表具有一定抗環(huán)境振動(dòng)性能;
6、可測(cè)介質(zhì)溫度達(dá)+250℃。
7、可實(shí)現(xiàn)不斷流拆裝傳感器,可實(shí)現(xiàn)放大器與傳感器分離(分離距離15m);
