在线密度计校准及计量应用

Application of On-line Densimeter Calibration and Metering

阐述了密度及密度系数的定义,介绍了密度计在线校准程序及数据处理方法,并且给出了偏离标定温度、压力对密度值影响的修正公式,同时,介绍了在线密度计计量应用情况。指出,采用在线密度计可有效监测计量过程密度变化情况,避免由于工艺条件和人工取样缺乏代表性造成计量失准。

Expounds the definition of density and density coefficient, and introduces the on-line densimeter calibration procedures and data processing methods, thus providing the formula to correct the influence of deviating temperature and pressure on the density value, Meanwhile, introduces the application of on-line metering of the densimeter, and points out that on-line densimeter can effectively monitor the density changes in the metering process so as to avoid the metering failure due to the processing conditions and hand sampling.
