Abstract: Daheiting reservoir has been in operation for over 30 years. Partition seepage of the main dam foundation was monitored by measuring weir. Artificial observation was carried out by reading of the scale installed on the side wall of the canal at the weir, which contained large error and exerted harmful influence on data analysis. Research on reading instrument was conducted. The new design not only solved the original problems, but also eliminated the difficulty in artificial observation. Further, it has been well proved in everyday use that it meets the requirements of monitoring and improves the management level.

Key words: safety monitoring, seepage monitoring, measuring weir, reading instrument
