摘　　要：本文介绍了一种基于HART协议的浮筒液位计的设计方案。3010G是测量液体的液位、界面。在介质温度350℃,或压力高达32MPa的工况条件下都能可靠测量。测量范围3m,能在易燃易爆强腐蚀的情况下使用(ia[d]ⅡCT6),精度为±0.5%FS,最小比重差为0.1g/cm3,带HART通讯协议,并有本机调试功能。多种安装方式,适合各种场合安装要求。This paper presents the design and implementation of the Float Type Level Transmitter based on HART protocol.In the medium temperature of 350 ℃,or pressure up to 32 MPa,under the working conditions can be reliably measured.Measuring range 3 m,can be flammable and explosive strong corrosion of the circumstances under which （ia [d] Ⅱ CT6）,accuracy ± 0.5% FS,the minimum proportion of deviation 0.1 g/cm3,with HART communication protocol,and have the machine debugging.A variety of installation,the installation requirements for a variety of occasions.
