数字量水堰的应用研究

通过对原理和试验数据的分析，指出了入堰流量和溢流水库的形式是数字量水堰在应用中影响精度的主要因素，并对它们做了定量的分析研究。结果表明，使用数字量水堰能够获得零至足够大的非恒定流，流量精度可以达到5％的全量程，并具有理想的稳定性。

Study on application of digital weirs

Based on an analysis of the principle of and test data about the digital weir, it is pointed out that the inflow into the weir and configuration of the overflow reservoir are important factors affecting the accuracy of the application of the digital weir. A quantitative analysis shows that, by use of the digital weir, unsteady flows of arbitrary flow rate can be easily obtained, and the accuracy of flow rate can reach 5% of the full measuring range, and that the digital weir is of high stability.
