在线悬移质泥沙测沙仪

功能用途

在线悬移质泥沙测沙仪应用于江河湖库悬移质泥沙在线监测,选用基于同位素、光电、초음파、振动测量技术的泥沙测量传感器,结合泥沙测算系统与无线远程监控技术,实现悬移质泥沙含沙量的实时监测。本次设计主要选择光电法测沙仪。

工作原理

光电法的在线悬移质泥沙测沙仪基于组合红外吸收散射光线法,采用双光束红外散射光逆投影成像技术,应用ISO7027方法连续精确测定悬浮物浓度。按照ISO7027红外散射光线技术不受色度影响测定悬浮物浓度值,可直接输出泥沙含量数据,实现实时在线监测。

测量原理:双光束红外散射光逆投影成像技术,内设自诊功能,保证数据稳定,数据可靠,并带自动清洗与斜率校正。
