时差法超声波热量表测量流量的修正算法
Flow correction algorithm on time difference type ultrasonic heat meter
摘要
Abstract
The theory of ultrasonic heat meter's flow measurement and error causes is analyzed.At the same time,based on the principle of fluid mechanics and combined with a large number of experimental data puts forward a modified method that is the lookup table method.The experimental results show that after modifying flow by look-up table method,the measurement error less than ± 2％ which reach to the national standard of ultrasonic heat meter.关键词
