Software design for steam flow totalizer 蒸汽流量积算仪的软件设计
In recent years , people have paid much more attention to the accuracy of flow measurement as technology progresses . the intelligent flow totalizer system in this design is combined with the spindle flowmeter , the embedded system techniques and serial communication techniques 近年来,伴随着工业生产、医疗卫生等领域的技术进步,人们对流量计量提出了更高的要求,而在全球自然资源供应日趋紧张的今天,提高流量测量精度更具有举足轻重的现实意义。
Abstract : based on the analysis of the mathematics models of saturation steam density and superheat steam density the paper states that the deviation of the detection on temperature highly affects the accuracy of intelligent flow totalizer . especially for saturation steam , the accuracy of the temperature detection circuit shall be designed higher than the accuracy of the instrument . thus a temperature detection circuit based on ratio method with high accuracy is introduced 文摘:在分析饱和蒸汽和过热蒸汽密度的数学模型的基础上指出,温度检测的偏差对智能流量积算仪的精度影响极大,尤其是饱和蒸汽,测温电路的精度应设计为远高于仪表的精度,同时引入一种基于比率法的高精度测温电路。
