摘　　要：介绍了超声波浓度计的测量原理及基本组成,由于进行了大范围的温度补偿和非线性修正,实现了硫酸浓度的在线检测,测量精度优于0.2%.The measuring principle and basic composition of the ultrasonic concentration meter are introduced. Because of the wide range temperature compensation and non - linear correction the on -line sulphur concentration detection has been implemented. The measuring accuracy is better than 0.1%.
