水流量标准装置性能评价与提高节流装置的标定精度

Performance Evaluation of Standard Flow Metering Devices and Improvement of Calibration Accuracy

对国内外水流量标准装置规程进行了分析.并对国内外水流量标准作了评估.针对电站性能试验用流量测量节流装置的特点,论述了提高节流装置标定精度的方法和途径,指出,应建立高精度的称重装置和自动测量系统。

Standard flow metering devices used in China and abroad are critically discussed. With a view on the special features of throttling flow measuring devices used in power plant tests,the way to increase calibration accurac is discussed and the necessity to set up weighting devices of high accuracy is stressed.
