Abstract: Due to the benefits of high precision, wide scope of monitoring and reliable measurement values, the hydrostatic levelling system has been widely used in the dam settlement monitoring. This paper mainly introduces the working principles of the hydrostatic levelling system and the factors affecting the measuring accuracy. Combined with its application in a diversion type hydropower station, the monitoring data as well as the influence of temperature on monitoring data are analyzed. Moreover, the key points in installation is presented, for reference.

Key words: settlement monitoring, measuring accuracy, temperature, installation
