本文对玻璃窑炉重油系统中常用的不同流量计量方法的精度进行了分析。分析表明，直接计量方法的计量误差最小，间接计量的误差最大。分析认为，在满足工艺要求的前提下应优先采用直接计量方法，同时认为，当出现过大的流量计量误差后，应首先考虑人为造成旁通泄漏的可能性。文中提出了防止人为旁通泄漏的措施，并简述了流量计选型应注意的问题。
This paper analyzes the accuracy of different flowmeters commonly used in glass furnace heavy oil system. The analysis shows that the direct measurement method has the smallest measurement error and the indirect measurement has the largest error. According to the analysis, the direct measurement method should be given priority to meet the technological requirements. At the same time, it is considered that when excessive flow measurement error occurs, the possibility of artificial bypass leakage should be considered first. In this paper, measures to prevent man-made bypass leakage are given, and the issues that should be paid attention to in the selection of flowmeter are briefly described.
