| Abstract: | 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. |
