流量非接触测量方法

A New Non-invasive Flow Measuring Method

    摘要
  • 摘要: 提出了一种流量非接触式测量的新方法，即用管外加热套对被测管段加热，因管内流体的流动使其上下游产生温度差，由铂膜电阻将此温差转换成电阻差，从而实现了利用不平衡电桥测量管内流体速度及流量的新构想.

     

    Abstract: A new method for non-invasive flow measurement is described, To heat the pipe by a clamp-on heater, the temperature difference upstream and downstream caused by flowing fluid is changed into the resistance via Pt-film resistances. Then, the flowrate can be measured using a non-balancing bridge.
