HR-LU渦街流量計主要用于工業管道介質流體的流量測量,如氣體、液體、蒸氣等多種介質。其特點是壓力損失小,量程范圍大,精度高,在測量工況體積流量時幾乎不受流體密度、壓力、溫度、粘度等參數的影響。無可動機械零件,因此可靠性高,維護量小。儀表參數能長期穩定。渦街流量計采用壓電應力式傳感器,可靠性高,可在-20℃~+250℃的工作溫度范圍內工作。有模擬標準信號,也有數字脈沖信號輸出,容易與計算機等數字系統配套使用,是一種比較先進、理想的流量儀表。

一、HR-LU渦街流量計測量原理:

式中 qVn,qV--分別為標準狀態下(0oC或20oC,101.325kPa)和工況下的體積流量,m3/h; 
Pn,P--分別為標準狀態下和工況下的絕對壓力,Pa;
Tn,T--分別為標準狀態下和工況下的熱力學溫度,K;
Zn,Z--分別為標準狀態下和工況下氣體壓縮系數。 
秒速赛车看 由上式可見,VSF輸出的脈沖頻率信號不受流體物性和組分變化的影響,即儀表系數在一定雷諾數范圍內僅與旋渦發生體及管道的形狀尺寸等有關。但是作為流量計在物料平衡及能源計量中需檢測質量流量,這時流量計的輸出信號應同時監測體積流量和流體密度,流體物性和組分對流量計量還是有直接影響的。
