文丘里管显示仪表稳定性分析研究

东深改造工程中建设有32个分水点,要求计量精度高,因此供水计量采用的是精度较高的文丘里管。但其配套的显示仪表在使用过程中出现了死机或掉电现象,在课题研究小组的试验、研究下,成功解决了显示仪表的稳定性问题。

The Analysis and Research for the Stability of the Display Instrument to the Venturi Tubes

32 water-divided points were constructed in the works of Dongshen reform, high measuring accuracy was required, so, the venture tubes with the comparatively high accuracy were adopted to the water supply measurement. But, the phenomena of deadlock and outage occurred to the associated display instruments during the operation, the problem of the stability to the display instruments was eventually resolved under the experiment and research of the topic research group.
