Method to improve accuracy mass measurement fluid in the tank

Considered two methods to improve the accuracy of measuring the mass of fluid in the tank based on the non-linear interpolation of the experimental calibration data. The first method is to find a transformation function mass and the total parameters of the fluid measured by monitoring with the help of the calibration model of the measurement process. The second method is based on the determination of an individual analytical dependence for the tank, connecting a lot of fluid, with its qualitative and quantitative parameters.
