                                                                                                                                                                                               渦街流量計利益許多,也適用于各類工況中流量的測量需求。關于渦街流量計的選型和安裝就有很大的學問。在人們挑選和安裝渦街流量計的時候,應關鍵考慮以下個方面:

                                                                                                                                                                                               1、因為渦街流量計是一種速度式流量計,漩渦別離的穩定性受流速影響,故它對直管段有必定的要求,一般是前10D、后5D;

                                                                                                                                                                                               2、測量液體時,上限流速受壓損和氣蝕現象約束,一般是0.5~8m/s;

                                                                                                                                                                                               3、測量氣體時,上限流速受介質可壓縮性改動的約束,下限流速受雷諾數和傳感器活絡度的約束,蒸汽是8~25m/s;

                                                                                                                                                                                               4、因為應力式渦街流量計對振蕩較為活絡,故在振蕩較大的管道安裝流量計時,管道要有必定的減震辦法;

                                                                                                                                                                                               5、因為應力式渦街流量計選用壓電晶體作為檢測傳感器,故其受溫度的約束,一般為-40~+300℃。

                                                                                                                                                                                               其他,渦街流量計安裝的許多嚴格要求是前后需求很長的直管段,會跋涉使用者的安裝本錢,也簡單遭到場所的約束。不過現在已經有一些廠家可以提供在流量計內部縮徑的規劃,這樣的規劃大大降低了用戶專門為渦街流量計裝備直管段的需求,從而為企業省下不少的安裝本錢。
