Calibration of the Hybrid, Mounting in the Tanks Systems for Measuring Mass of the Liquid

Abstract

In this article is presented your attention calibration method of the measuring systems for the mass of the liquids in tanks in the place of the exploration. Systems consist of level gauges and devices for measuring hydrostatic pressure of liquid. Calibration is performing to measure the level of liquid from dip-point and density of liquid by measuring standards simultaneously with measure of vertical distance from reference point of the level gauge to liquid surface and hydrostatic pressure of liquid by system. Measurement results are adjusted by list square solution method and after that obtained geometrical and other parameters (biases) of the system. Parameters (biases) enter to system like that correction. Uncertainty evaluation is performing for parameters of the system and for liquid mass in exploration strict by list square method with considers correlation between parameters and results of measurement.
