采用五孔球型探针现场测流技术对南水北调东线工程源头泵站枢纽江都第一、二抽水站多台机组改造前后进行流量测试。测试结果表明 ,五孔球型探针法测试方便 ,现场测试精度高。
A five-hole ball-type probe on-site flow measurement technology was used to test the flow rate before and after the transformation of multiple units at Jiangdu No.1 and No.2 pumping stations in the source project of the East Route Project of South-to-North Water Diversion Project. The test results show that the five-hole ball probe test convenient, high-precision field test.
