当液化石油气体积采用容积式流量计测量 ,相对密度采用压力密度计手工测量的计量方式时 ,依据现有的质量计算标准 ,其质量无法进行计算。根据生产实际需要和实践经验 ,提出了在以上测量条件下的一种近似质量计算法 ,用该法对液化石油气的质量进行计算 ,精度可以满足液化石油气交接计量的要求。
When the volume of liquefied petroleum gas is measured by volumetric flowmeter and the relative density is measured by manual pressure density meter, the quality can not be calculated according to the existing quality calculation standard. According to the actual production needs and practical experience, an approximate quality calculation method under the above measurement conditions is proposed. With this method, the quality of liquefied petroleum gas is calculated and the accuracy can meet the requirements of liquefied petroleum gas delivery and measurement.
