Improving the efficiency of operation of trunk pipelines. However, to assess the activities carried out, accurate and reliable information about the amount of the pumped and stored product is required. Existing methods for measuring the amount of liquid and methods of using capacity measures lead to large errors in calculations. Measurement and tampering with the turnover reporting process depends on the “human factor” and the prerequisites for introducing measurement and tampering into the turnover reporting process. In operation, an automatic system for measuring pressure and temperature by product layers based on the hydrostatic principle of operation, which allows calculating the gross mass of oil. Also, the paper analyzes methods for increasing the accuracy of calibration tables obtained in the process of tank calibration. The proposed system improves the measurement accuracy, productivity and operational efficiency of tank farms.

Рассматриваются различные подходы к оценке результирующей погрешности определения интегральных характеристик сигналов по отдельным мгновенным значениям, обусловленной отклонением реальных сигналов от используемой гармонической модели.
