                                                                                                                                                                                            渦街流量計的選型盡或許不要運用流量作業在下限極限值,故流量計的口徑應盡或許小,以取得更大的流速和流量范圍。流量計應運用在介質作業壓力和溫度范圍的技術參數內。不要刻意選用高壓力等級和超高溫度的外表,應根據實踐作業壓力和溫度選用外表,后者價格要高些。



                                                                                                                                                                                            在爆炸風險場所,應選用防爆型流量計。渦街流量計的下限流量取決于介質的工況密度和運動粘度,其上限流量一般不受介質壓力和溫度的影響,因此確認流量范圍只需確認實踐可用的下限流量即可。核算出下限流量后,查流量范圍表即可確認相應口徑。

                                                                                                                                                                                            渦街流量計的保養及運用:渦街流量計應定時清洗渦街流量計的探頭,查看中曾發現,個別探頭檢測孔已被污物堵塞,乃至被塑料布裹住,影響了正常測量。渦街流量計定時查看接地和屏蔽狀況,消除外界干擾。有時候指示問題是由于遭到干擾所至。

                                                                                                                                                                                            渦街流量計裝置環境濕潤的探頭。應定時烘干一次,或作防潮處理。由于探頭自身并末作防潮處理,受潮之后影響運行。渦街流量計外表的數據資料的管理應引起足夠的注重,以利于日后的作業。
