Abstract:

In this study, we propose a new approach for determining the density of liquid based on the gamma transmission technique in combination with Monte Carlo simulation. This approach involves analysing the sensitivity of the measurement whilst changing the diameter of a tube containing a liquid and then based on the simulated data to construct a linear calibration curve. The proposed approach is validated by measuring the density of nine liquids with a density in the range of 0.6–2.0 g cm−3 for four various diameters of the tubes. The results showed the percent di erence between the measured and the reference densities of less than 5% for most measurements, and the relative uncertainty of measurements of less than 4%.
