產(chǎn)生的誤差很小,仍在儀表精度范圍內(nèi),不需要任何修正即可使用。管徑小于表徑,但兩者之差在一定范圍內(nèi)。一般來講,DN15~DN1者,小于或等于3%;DN15者,小于或等于1%。可通過對(duì)儀表系數(shù)的修正,將測(cè)量影響消除。管徑與表徑相差較大,超過上述允許的范圍。應(yīng)設(shè)法更換為與表徑一致的直管段。板流量計(jì)維護(hù)措施渦街流量計(jì)應(yīng)與孔板流量計(jì)一樣,不加旁路閥和前后截止閥,節(jié)省投資。但帶來的問題是儀表不能被不停工拆下維護(hù),筆者認(rèn)為:由于孔板流量計(jì)無可動(dòng)部件、耐磨損、免維護(hù),不需要加維護(hù)旁路;為保證其工作可靠。
