基于铜悬臂梁开关的低功耗热式流量计研制

Research of low consumption flow meter based on cu cantilever switch

为了降低热式质量流量计的功耗,文章设计基于悬臂梁的热式质量流量计开关,将其置于气流通道的前端,用于控制流量计电路的通断。文中采用铜作为悬臂梁的材质,并对其效果进行仿真和验证,证明铜悬臂梁适合作为热式流量计开关,该流量计具有推广应用价值。

In order to reduce consumption of thermal flow meter,and prolong its working life,this article added a cantilever in flow meter as switch,put the cantilever in front of sensors in the aisle,and control the circuit to save the energy.This article use nano-imprint method to realize cantilever base on copper.It is proved that the copper cantilever beam is suitable as a thermal flow meter switch,and the flow meter has popularization and application value.
