摘要/Abstract

摘要： 　通过对影响流量计标定精度的因素（如计数及计时的精度、水流的稳定性、标准罐体积的计量方法、换向器的切换速度、温度等）进行深入研究，并采取相应的措施，提高了标定精度，确保了标定结果的准确性。运用此高精度的标定系统，对锥形流量计进行了标定，并对标定出的流出系数进行科学处理，分析了其标定结果的误差精度，确保了标定数据的可靠性。流量计的测量误差在３‰以内，可达到现场流量测量的要求。

Abstract: hrough in-depth study of factors affecting the accuracy of the flowmeter calibration, such as counting and timing accuracy, the stability of the flow, the standard tank volume measurement methods, the switching speed of the commutator, temperature, and so on, to improve the calibration accuracy, and ensure the results of calibration accuracy. Use this high-precision calibration system, to calibrate the cone flowmeter, and scientific processing of the calibration of the flow coefficient, analysis error accuracy of the calibration results, and ensure the reliability of the calibration data. Flowmeter measurement error less than 3 ‰ can be achieved by field flow measurement requirements. 
