摘　　要：目前火电厂普遍应用湿法脱硫系统,针对传统湿法脱硫系统密度计探头易磨损及测量管路频繁堵塞问题,设计基于称重传感器和STM32的在线监测含有颗粒物混合液体密度计。密度计测量方法简单,测量精度高,能够实现对管道中含颗粒物流动液体的密度进行快速、在线测量,具有很高的使用价值。Nowadays,wet desulfurization was widely applied in coal-fired power plant system. In view of problems of continual probe abrasion of traditional density meters and frequent congestion of the measuring line,one kind of densimeter was designed based on weighing sensor and STM32 to realize on-line monitoring to flowing liquid containing particulate matter. The densimeter has a simple measurement method,high measurement precision and convenient installation and it can realize fast and on-line measurement of density of flowing liquid containing particulate matter in the pipeline. The densimeter has very high use value.
