摘要
介绍了一种传热原理的组合热膜探头.在对该组合热膜探头的温度特性以及温度补偿性能进行实验研究的基础上,设计了具有温度补偿的气体流量计,并在音速喷嘴检定装置上对该流量计进行了流量检测实验.对实验结果的拟合和处理表明,该气体流量计的测量精度优于0.5%,流量范围度大于60:1.
An assembled hot-film probe which was based on the principle of the heat transfer was introduced. On the basis of tests on the temperature characteristics of the hot- film probe and experimental research on the temperature compensation performance, a gas flow meter for temperature compensation was designed. The flow measuring experiment of the flow-meter was tested on Sonic Nozzle. The results of experiment data processing proved that its precision is below 0.5% and its measuring range is over 60 ： 1.
