水电部南京自动化研究所目前正在研制一种自动测量土坝内部渗透水位的仪器,其技术指标如下: 1、水位最大变幅10米 2、水位最小读数1公分 3、测量精度——1％ 4、遥测测压管(水位)数——100点 5、遥测距离——不短于1公里 6、传输线数——设在大坝上的中转站到控制室共用七根线。 7、测量和记录方式: 1)全自动——人工启动后,仪器即开始自动巡测第一点直至第100点的测压管水位、并由数字打印机把各管的管号和水位数值全部自动打印在记录纸带上,同时有数码管直接显示以上各管号与水位数值、测量100点总历时不超过10分钟。
Nanjing Institute of Automation of MEW is currently developing an instrument to automatically measure the infiltration water level inside the earth dam. The technical indicators are as follows: 1, the maximum amplitude of the water level is 10 m 2, the minimum water level reading is 1 cm 3, the measuring accuracy is -1% 4 , Telemetry piezometric tube (water level) number - 100 points 5, telemetry distance - not less than 1 km 6, the number of transmission lines - in the dam on the transfer station to the control room shared seven lines. 7, measurement and recording methods: 1) automatic - manual start, the instrument began to automatically patrol the first point until the first 100 points of the piezometric water level, and by the digital printer to the pipe number and water level all Automatically printed on the tape in the record, at the same time a digital control directly displays the number of the above water pipes and water, measuring the total duration of 100 points less than 10 minutes.
