目前北京市有大、中、小型水库86座,实现水工观测自动化的不足百分之五,大多数水库观测还是沿袭建库初期的一套方法,即使有改进,步子也很小。十三陵水库自1958年建库至1984年10月的二十多年中一直是使用测绳和测钟量测水位的,既费工还保证不了精度。为于改变观测落后的现状,提高管理水平,水库管理处与水电部自动化仪器厂合作,在水库安装了SD—79A大坝测压管水位遥测仪,于1984年10
At present, there are 86 large, medium and small reservoirs in Beijing, which realize less than 5% of the automation of hydraulic observation. Most reservoirs still follow the initial method of reservoir construction. Even if there are improvements, the paces are small. The Ming Tombs Reservoir has been built from 1958 to October 1984 for more than two decades. It has been the use of rope and clock to measure the water level, which can not guarantee the accuracy of the work. In order to change the status quo behind the observation and improve the management level, the reservoir management department and the Department of Automation Instrument Factory in cooperation with the installation of SD-79A dam piezometer water level telemetering, in 1984 10
