【摘要】 全沙含量在线监测是根据置换称重法的原理，通过特殊设计的传感器与微机数据采集处理系统相结合的测量方法，具有测量范围宽，适应流量下限低，测量精度不受泥沙粒度的影响，并且具有自动按时间顺序记录含沙量变化全过程的特点。是目前降雨侵蚀实验中的理想装置。更多还原

【Abstract】 The principle of replacement weighting method has been used in the total sediment load monitoring. Through using the specially designed digits sensor and the omputer-based dig-its collection system,the monitoring device has a wide sediment concentration measurement range,it can monitor and record sediment concentration processes automatically and can be used in very low runoff discharge. The observation precision of the device can’t be affected by sedi-ment partical size in runoff. The device is available for rainfall erosion experiment.更多还原
