唐山天辰电器基于IAPWS-IF97的高精度蒸汽流量仪表的研制凌波，徐英(1.天津大学电气与自动化工程学院天津300072；2.塘沽第一职业中专天津300451)引言当前多数智能仪表都采取了一定的流量补偿技术，但补偿的数学模型建立过程考虑并不十分周全，计量的准确性仍然不高。
蒸汽流量计量方案((含宽量程问题,蒸汽密度计算问题))
相同的，流出系数C的计算式是以大量实验所确定的数
值为依据，并以标准的形式给出。 传统的节流装置量程比较窄，主要是流出系数C、 可膨胀性系数ε等中间参数引起的。传统的节流式流 量计是将流出系数C和可膨胀性系数ε视为定值（C
和ε由专门的节流装置设计计算软件计算得到），置 入现场的流量积算仪。下图是一台孔板流出系数曲线。
会议又将骨架表的压力和温度范围放宽，并加以改进。
随着计算机技术的发展，国际水蒸汽会议认为推导一 套工业应用的水和水蒸汽性质公式很有必要，因此在 1963年（纽约）的第六届会议上成立了国际公式化委 员会（IFC），这个国际会议推出的公式是由一整套
方程式组成，用该公式计算出的数值，不论在哪一点，
都在骨架表的允差之内。目前大多采用的水蒸汽表的

从图中可以看出,当雷诺数ReD≥2×105时，孔板
的流出系数C进入线性区，流出系数C方可以认为是一
个常数；当雷诺数ReD≥4×105时，喷嘴的流出系数C 进入线性区，流出系数C方可以认为是一个常数。在实 际测量中，由于流量变化而使雷诺数小于界限值的情 况时有发生，如果不进行修正，仍按计算书的C值来计
非标准节流装置
●结构创新，促进仪表技术发展（注意总结应用经 验）。
●无标准支持（呼吁有关部门加速建标准）。
●仪表须实流标定（注意：仪表用液体标定，不可 用于蒸汽计量）。 ●可用于一般场合流量计量和某些工艺控制量监测； 贸易计量必须实流标定。 ●对结构安全给予重视。
传统孔板 ①入口边缘易磨损 ②阻损大 ③易变形，一般采用非 定值 ④检定周期短（一年）
C=0.6176；平均值=0.6139，即在3×104～1×104范围
蒸汽密度对照表3篇
蒸汽密度对照表第一篇：蒸汽密度介绍蒸汽密度是蒸汽与空气或其它气体相比较的相对密度。
通常是用在蒸汽能量计算、热力学分析和工程计算中。
蒸汽密度会受到蒸汽的压力、温度和湿度的影响。
在常见的工程应用中，通常使用相对湿度为100%的干蒸汽作为密度进行计算。
基准密度是指在标准温度和压力下，标准大气压强下，气体的密度。
在国际标准大气压（101.325kPa），温度为15℃，水的相对湿度为0%时，蒸汽密度为0.597kg/m³。
蒸汽的密度是热力学计算的重要参数，对于蒸汽管道、蒸汽锅炉等热力学系统的设计和计算有着十分重要的影响。
第二篇：蒸汽密度对比蒸汽密度与压力和温度的变化有密切关系，随着压力和温度的不同，蒸汽密度会发生变化。
下面对常见的蒸汽密度进行对比分析。
在标准大气压（101.325kPa）下，蒸汽密度为0.597kg/m³；在2.0MPa压力下，若温度为150℃，则蒸汽密度为5.19kg/m³；若温度升高至200℃，则蒸汽密度为8.39kg/m³；当温度高达250℃时，蒸汽密度则为12.30kg/m³。
由此可见，蒸汽温度对密度的影响很大。
蒸汽密度的变化，对于蒸气管道和蒸汽锅炉等设备设计和运行都有很大的影响。
因此，在热力学分析和工程计算中，必须准确地计算蒸汽密度，才能保证热力学系统的正常运行。
第三篇：蒸汽密度计算公式计算蒸汽密度时，常见的公式为：ρ=0.622×P/RT其中，ρ表示蒸汽的密度（kg/m³），P表示蒸汽的压力（Pa），R表示气体定压比热（J/(kg·K)），T表示蒸汽的温度（K）。
此外，还可以利用万能气体常数公式计算蒸汽密度：ρ=P/RT其中，ρ、P、R、T的含义与上一公式相同。
以上两种计算蒸汽密度的公式，根据不同的应用场景和数据可直接代入计算，以计算出准确的蒸汽密度。
总的来说，蒸汽密度是热力学中的重要参数，对于热力学系统的设计和计算具有重要的作用。
