Annotation:
Development of equations of state of liquefied natural gas to determine the amount of energy in commodity transport operations. To increase the efficiency of measuring systems, it is necessary to provide control and control of the parameters of technological processes to create a single-phase state of the liquid flow with a minimum amount of vapor phase during measurements in production, storage and transportation. The complex task of improving the accuracy and efficiency of energy quantity measurement systems is based on the equations of state of natural gas and new procedures for assessing the reliability of sampling. Algorithms and measurement technologies for determining the calorific value, density, volume and mass measurements, which take into account the parameters of technological processes and physico-chemical properties of liquefied gas, influencing factors not previously taken into account.
