                                                                                                                                                                                        流量計裝置運用留意事宜:

                                                                                                                                                                                               一、流量計外表裝置前,管道有需要徹底清洗,在整個管路系統中,若無嚴峻的過濾裝置時,應在外表前裝置過濾器,以防雜質進入表內。

                                                                                                                                                                                               二、流量計外表應裝置在泵的出口端,流量調節閥應裝置在外表的下賤。運用時先打開上游截止閥,然后緩慢打開下賤流量調節閥或截止閥。禁止忽然打開或封閉。

                                                                                                                                                                                               三、流量計外表在運用時,應使表內流滿液體。被測液體內不該混有氣體,不然測出氣和液的混合容積,使測量禁絕,液體內混有氣體時,有需要在外表上游裝置氣體分離器。

                                                                                                                                                                                               四、管道中的流量不該急劇添加或削減,應防止管道振蕩、水力沖擊和壓力急劇不堅定等現象,不然將影響外表正常工作。

                                                                                                                                                                                               五、流量超過規矩大流量時,流量計跟著轉速進步而磨損添加、且壓力丟失急劇添加,應防止運用。低于小流量,雖仍能計量,但過失增大。流量計的起動流量約為大流量的2%,正常工作流量好為大流量的70%-80%。

                                                                                                                                                                                               六、由于測量高粘度液體時,一般均將液體加熱以下降粘度,然后在管道內流轉(帶保溫夾套型流量計)。當外表停用后,外表內充溢的液體因冷卻而變粘,如再要啟用,有需要用蒸汽或其他方法在表體外部加熱,然后下降液體的粘度,待外表內液體粘度下降后才干運用。不然粘液會咬住傳動零件,致使外表損壞。

                                                                                                                                                                                               七、被測液體溫度不該高于規矩值,不然,外表不能正常工作,甚至會卡住不動,計數器部分在高溫下簡略損壞。液體溫度改變也會形成粘度影響的附加過失。
