热式气体质量流量计的设计

Design of Thermal Gas Mass Flowmeter

利用单片机作为主控器件来控制气体的质量流量及其显示,外壳采用316L不锈钢材料的温度传感器组成的热式气体质量流量计及自动控的变送器,通过采集流量、A/D转换以及对CPU的控制,再通过数码管显示等一系列硬件功能和软件功能的辅助实现,共同完成对流量测量的控制.

Using single chip microcomputer as main control device to control the quality of the gas flow and shows that the shell of the machine adopts the material of 316 L stainless steel temperature sensor consisting of thermal type gas mass flowmeter and automatic control of the transmitter,flow through acquisition,A/D conversion and control of the CPU,and through digital tube display and so on A series of hardware and software functions of the auxiliary implementation,complete control of the flow measurement.
