摘要
为提高粘稠和高温环境下液位的测量和控制精度,提出了一种基于HART协议的核辐射法液位测量和控制系统。HART模块由A5191和AD5421组成,以STM32为控制核心,采用校正平均算法减小测量误差。详细阐述了系统软硬件设计方案,实现了液位的精确测量和控制。
In order to improve precision of liquid level measurement and control under high viscosity and high temperature condition, a nuclear radiation method of liquid level measurement and control system based on highway addressable remote transducer（HART） protocol is proposed. The HART module is composed of A5191 and AD5421 uses STM32 as control center and use correction average algorithm to minimize measurement errors. Hardware and software design schemes are expounded in detail and precise measurement and control of liquid level are achieved.
