介质流速对科氏质量流量计选型的影响
发布时间:2017-11-28   点击次数:461次
   科氏质量流量计是利用科里奥利原理测量质量流量的仪表,科里奥利原理描述的是旋转系统上沿着半径方向作直线运动物体所受到的有别于离心力的力,这个力称为科里奥利力。

  科氏质量流量计测量精度高,测量不受介质物性影响,69棋牌无上、下游直管段长度的要求。而且科氏质量流量计是智能化程度很高的仪表,其变送器除了质量流量,能输出转化成4~20mA或者脉冲信号或者总线信号的体积流量、密度、温度、粘度和浓度等流程参数。

  科氏质量流量计69棋牌按测量管段数可分为单管型和双管型;按测量管形状可分为弯曲形和直形,弯曲形的测量管也分Ω字形、S字形、J字形、三角形等;按测量管材质分有316L、904L、C-22合金、钛和锆等;按流量计安装方式分有螺纹、法兰、卡箍、CajonVCO、Swagelok等。根据工程实际情况和流程参数,选择合适的形状、材质、公称通径、公称压力和安装方式的质量流量计。

  综上所述,科氏质量流量计69棋牌选型时,需要考虑其压损是否被整个工艺流程所允许。要求限制压损,也就限制了在公称通径一定下的介质流速上限范围。或者在保证介质质量流量或体积流量上限的要求下,选择大一级的公称通径,扩大流通面积。
