Description
Summary:Tank calibration curve proves to be one of the most important characteristics in the context of oil products related metering and calculation operations inclusive of those performed in the environment of Unified Automated Accounting System of Diesel Fuel and Other Oil Products (EASU DT). In accordance with GOST 8.570 - 2000 all the petroleum storage reservoirs of petroleum depots (inclusive of JSC RZD fuel storage depots), boring pumps and fuel-filling stations shall be calibrated every fifth year. Nonreversible plastic deformation of reservoirs, thinning of their walls due to rusting, sagging of bottoms etc. lead to considerable calibration curve variations and possibly to errors of significance during performance of metering operations in the course of stocktaking and operators changeover as well as to other sort adverse effects. The proposed automatic method of reservoir calibration making use of fuel dispenser under conditions of routine operation of fuel storage depot contributes to better accuracy and credibility of calibration, reduction in its timing and corresponding costs. Application of such method and equipment allows to interpret unmanageable systematic error of the fuel dispenser as a random one and (with more statistics available) to reduce resulting error of fuel dispenser from ±0.25 % practically up to до ±0.05 %.
