Оценка погрешности измерений массы товарной нефти и нефтепродуктов с использованием счётчиков жидкости

Abstract

Functional relationship between mass of commercial oil and petroleum products and measurement results of their parameters: density, volume, pressure and temperature measured at laboratory and operational conditions, coefficient of thermal expansion at atmospheric pressure and at gauge pressure in operational conditions is presented. The expression for estimation relative error boundaries of indirect measurement results of oil and oil products mass with employment of liquid meters is obtained. Results for kerosene, aviation kerosene and light diesel fuel are showed in tables.
