插入法蘭渦街流量計(jì)
插入式渦街流量計(jì)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4~20mA電流信號(hào)。
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 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℃~+350℃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。

安裝要求
在安裝精簡(jiǎn)型熱式氣體質(zhì)量流量計(jì)前請(qǐng)確認(rèn)管道的實(shí)際內(nèi)徑和壁厚。
將熱式氣體質(zhì)量流量計(jì)的其余部分一起裝入專用球閥內(nèi),根據(jù)實(shí)際管道內(nèi)徑和壁厚計(jì)算出要插入的深度。這一步可以插入個(gè)大致尺寸并用手?jǐn)Q緊螺母。
轉(zhuǎn)動(dòng)傳感器連桿,使標(biāo)記箭頭與介質(zhì)流動(dòng)方向相同。
根據(jù)現(xiàn)場(chǎng)測(cè)得的數(shù)據(jù)換算出在傳感器連接桿上的相應(yīng)刻度,鎖緊螺母即可。
如果您是橫向安裝的本款儀表的顯示屏可以90°180°270°的靈活安裝,滿足你現(xiàn)場(chǎng)實(shí)際需要。
