摘　　要：结合现场总线技术,介绍一种基于总线功能HART协议的智能浮子流量计的软件、硬件设计,并论述了流量计的低功耗设计思路。In this paper, the background of producing and specialty the field-bus is introduced. An intelligent variable-area flow-meter based on field-bus HART Protocol is designed. This paper also discusses the hardware design and the software design as well as the technique of ultra-lower power consumption in this intelligent variable-area flow-meter.
