| 摘 要： | 传统的密度计常采用的4-20mA电流输出或有线RS232／485串口通讯距离较短，网络节点数少和前期布线与后期系统升级维护过程繁琐。文中设计了一种带有ZigBee无线网络通讯功能的智能压差式液体密度计，采用两个独立的压力传感器取代传统的压力探头的测量方案和引入ZigBee无线网络功能，使得密度计具有通讯距离远、成本低、实时性强、网络节点数多等特点。

| Abstract: | Traditional density meters often use 4-20 mA current output or wired RS232/485 serial port which involves a short communication distance, a few network nodes and complicated wiring process in the earlier stage and complex system updating and maintenance process in the later stage. This paper de- signs an intelligent differential pressure liquid density meter with ZigBee wireless network communication function, replaces the traditional measurement program of pressure probe with two independent pressure sensors and introduces ZigBee wireless network function, making this density meter characterized by long communication distance, low cost, strong real-time capability and many network nodes etc. |
