摘　　要：介绍了一种基于电磁感应原理的在线浓度计,通过对溶液电导率和温度的测量,计算出被测溶液的浓度。浓度计在某化工厂硫酸装置和硝酸装置进行了应用,结果表明在线浓度计测量及时准确,与实验室采样分析比对误差在允许范围内,仪表耐腐蚀性能较好,能够有效指导装置的生产运行。An on-line concentration meter based on the principle of electromagnetic induction is introduced. The concentration of the measured solution is calculated by measuring the conductivity and temperature of the solution. The concentration meter has been applied in the sulphuric acid plant and nitric acid plant of a chemical plant. The results show that the on-line concentration meter measurement is timely and accurate, the comparison error with the laboratory sampling analysis is within the allowable range, the corrosion resistance of the instrument is good, and can effectively guide the production and operation of the plant.
