【摘要】 SJ－911型超声波流量计为南京自动化研究所生产，此套装置自1996年4月在漫湾发电厂安装使用以来，运行情况良好。它在管道中测流时，不破坏流场，没有压力损失，不影响正常工作，测流费用少，适用于大小管径，能观测水轮机流量的整个过渡过程。更多还原

【Abstract】 The Model SJ - 911 ultrasonic flowmetr being used in the Manwan Hydropower Plantwas made by the Nanjing Antomation Research Institute. Since its operation it has worked successively. While measuring flow in the pipeline, it does no damage the flow field, does not causepressure losses and does not produce any twact on normal operation of the power Plant. It can beused to measure flow in pipes with various diameters and to observe the whole transition process ofthe turnbine flow. Its folw measuring.cost is uite low.更多还原
