| 摘 要： | 本文利用电感传感器原理检测浮子位移的变化,实现玻璃浮子流量计的信号远传。采用玻璃锥管内嵌铁芯,锥管外缠绕漆包线的方法设计了电感传感器,然后在钟罩式气体流量标准装置上对该传感器进行了实验研究,通过对实验数据拟合分别得到浮子刻度与线圈电感的近似线性关系和线圈电感与气体流量的函数关系即流量测量模型,并对此模型进行了验证,其精度优于2.5级。

| Abstract: | To achieve the signal distant transfer of glass tube variable area rotameter,inductance coil was designed by iron core embedded in the glass Cone tube and enameled wire on the outside of the glass tube.Then experimental studies on inductance sensor was made by bell gas flow standard installation.The approximate linear relation between calibration of floater and inductance value was obtained and the functional relation between inductance value and gas flow rate was presented.Finally,the model of measuring gas flow rate based on inductance sensor was verified,the results showed that the measuring accuracy was within 2.5%. |
