Estimation of Measurement Errors for the Mass of Commercial Oil and Petroleum Products Using Liquid Counters

We present the dependence of the mass of commercial oil and petroleum products on the measured parameters – density, volume, measured fluid counter, pressure and temperature in operating and laboratory conditions, the volumetric expansion coefficient under atmospheric and gauge pressures in operating conditions at 15°C. We obtain an expression for the estimation of the relative error of indirect mass measurements of petroleum products. We present results of mass measurements for kerosene, aviation kerosene, and light diesel fuel.
