    喷嘴流量计适用范围

    该喷嘴流量计采用标准喷嘴作为节流件

    公称直径:50mmDN500mm
    公称压力:PN32MPa
    雷诺数范围:0.30≤β≤0.44时,70000ReD107
                   0.44≤β≤0.8时,20000ReD107
    孔径比:0.30≤β≤0.80
    精度:1                                                                                   
    喷嘴流量计结构形式
    标准喷嘴由垂直于轴线的入口平面部分A、圆弧形曲面BC所构成的入口收缩部分、圆筒形喉部E和为防止边缘损伤所需的保护槽F组成,其取压方式上游取压口采用角接取压,下游取压口可按角接取压设置,也可设置于较远下游处。喷嘴总长度
    0.30≤β≤2/3时,喷嘴长度=0.6041d
    2/3≤β≤0.80时,喷嘴长度=0.4041+0.75/β-0.25/β2-0.52250.5d
