VF Visi-Float®浮子流量计(转子流量计)

VF系列Visi-Float®浮子流量计系列包含VFA、VFB两个规格,是一条直读、精密机械加工、透明的丙烯酸酯体流量计,适用于气体和液体的应用。Visi-Float®流量计的制造有着60多年的烯酸酯流量计加工经验。该系列包括2"(51毫米)和4"(102毫米)刻度与可选的精密计量阀。

VFA:2"(51毫米)刻度
VFB:4"(102毫米)刻度

介质:兼容气体或液体

接液材质:阀体:丙烯酸塑料;O形环:Buna-N(可提供氟弹性体);金属部件:黄铜标准,不锈钢可选;浮子:不锈钢,黑玻璃,铝,K蒙奈尔铜镍合金(视范围而定)

温度和压力限制:无阀: 100 psig (6.9 bar) @ 150°F (65°C); 150 psig (10 bar) @ 100°F (38°C); 有阀: 100 psig (6.9 bar) @ 120°F (48°C).

精度:VFA = 5% of FS; VFB = 3% of FS.

过程连接:1/8"NPT内螺纹. VFB-85和-86是 1/4" NPT背部连接或者3/8"NPT顶端连接. 这些范围没有黄铜阀门.

刻度长度:VFA: 2"; VFB: 4"

安装方向:垂直

重量:VFA: 4.0 to 4.8 oz (.11 to .14 kg); VFB: 7.2 to 8.8 oz (.20 to .25 kg).

认证:符合欧盟第2011/65/EU(RoHS II)号指令的技术要求
