MEASURING SYSTEM OF MASS PETROLEUM when shipped in rail tank cars

摘要

The invention relates to the art of petroleum weight measurement when shipped in tank cars using weights. Proposed measuring system comprises a weighing device consisting of one or more modules, which are supported on load cells; microprocessor conversion device, processing, presentation and storage of the measurement results, wherein to improve accuracy of measurement of weight of the product introduced microprocessor device for the automated input in a weighing result correction that takes into account buoyancy ambient (buoyancy tanks). Microprocessor correction input device receives from the measuring devices or the keyboard the values ​​initial parameters (density of the product, the product temperature, ambient temperature and pressure), a determination and input of correction to the weighing result. Relative correction amount for the oil (according to the product of density and the measurement conditions) is from 0.12 to 0.18 percent by weight of the measured value. 1 pt. Formula. 1 features.
