LUX智能旋進旋渦(wo)氣體流量計(ji)流量計(ji)的選型

1.用戶在選型(xing)時,應根據管道公(gong)稱壓(ya)力(li)(li)、介質(zhi)zui高壓(ya)力(li)(li)、介質(zhi)溫度、介質(zhi)組(zu)分(fen)情況(kuang),流量(liang)范圍及(ji)信號輸出要求合(he)理選擇流量(liang)計的型(xing)號規(gui)格

2.為(wei)使(shi)(shi)流量計的使(shi)(shi)用性能*,流量計的使(shi)(shi)用范圍在大流量的20%~80%范圍內比較(jiao)合適(shi)。

3、流量(liang)計出(chu)廠(chang)時(shi)的標(biao)準輸(shu)(shu)出(chu)配置(zhi)是:具(ju)有(you)工況脈沖(chong)信(xin)號輸(shu)(shu)出(chu)(三線制)、標(biao)準流量(liang)信(xin)號輸(shu)(shu)出(chu)或RS485通訊輸(shu)(shu)出(chu)若要求有(you)其它(ta)輸(shu)(shu)出(chu)功(gong)能時(shi),請在(zai)訂貨時(shi)說

4、選型(xing)實例已知某(mou)一根氣管線的實際工作壓力為(表壓)0.8MPa-1.2MPa、,介質溫度范圍為-5て-+40C,供氣量(liang)(liang)為3000~10000m/h(標況流量(liang)(liang)),在不(bu)考慮天然氣組分的情況下,要求確(que)定流量(liang)(liang)計(ji)的規格(ge)型(xing)號。
