| Abstract: | The standard calibration in hydrological stations asks for precision measuring,therefore,the second-class leveling is always carried out in order to ensure the measurement accuracy.The advanced digital level DiNi12,combined with indium-watt bar-code scale-plate,is adopted in hydrological station observations in zhejiang District,Taihu Basin.The principle,performance and error sources of digital level DiNi12 are analyzed based on the practice,and the data process of the second-class leveling and accuracy eva... |
