渦輪流量計是怎么安裝的？

時間 : 2021-09-16 作者 : 麥克傳感器股份有限公司

（1）安裝場所
渦輪流量計傳感器應安裝在便于維修，管道無振動、無強磁干擾與熱輻射影響的場所。安裝在室外時，應有避直射陽光和放雨淋的措施。
（2）安裝要求及注意事項
渦輪流量計水平安裝的傳感器要求管道不應有目測可覺察的傾斜（5°以內）垂直安裝的傳感器管道垂直偏差應小于5°，流體方向應有下向上。
不能停流的場所，應加裝旁通和截止閥。
若流體含有雜質，則應在上游側裝過濾器；若含有氣體，則應在上游側裝消氣器。過濾器和消氣器的排污口和消氣口要通向安全的場所。
流量調節閥應裝在傳感器下游，上游的截止閥在測量時應全開，且都不得產生振動和外泄。對于可能產生逆向流的流程應加止回閥以防流體反向流動。
傳感器應與管道同心，密封墊圈不得凸入管路。傳感器不應在水平管線的最高點，以免管線內聚集的氣體（如停流時混入空氣）停留在傳感器處，不易排出而影響測量。
傳感器前后管道應支撐牢靠，不產生振動。對易凝結流體要對傳感器及其前后管道采取保溫措施。
傳輸電(dian)纜(lan)常用雙芯或三芯帶屏蔽(bi)信(xin)(xin)號電(dian)纜(lan)，屏蔽(bi)信(xin)(xin)號電(dian)纜(lan)最好在(zai)顯示(shi)儀表（流量積算儀或流量計算控制儀）端接地(di)，傳輸路(lu)徑不應與(yu)動(dong)力(li)電(dian)源(yuan)線平行，也不要敷設在(zai)動(dong)力(li)電(dian)源(yuan)線集中(zhong)的(de)區域(yu)。
