摘要
叙述了基于PIC单片机的两线制低功耗流量显示仪的设计方法。给出了利用涡街等流量传感器输出的脉冲频率信号进行计数和利用温度、压力信号进行补偿的流量测量原理。介绍了两线制、低功耗流量显示仪设计和实现过程中的一些关键技术问题。
The design of flow measurement display meter with twowire supple & low power based on PIC microcontroller is described,and the theorem of flow measurement by using the pulse or frequency signal of vortex transducer to count and temperature & pressure signal to compensate is also introduced.Some key techniques about the design and implementation of the flow measurement display meter are presented in detail.
