dc.description.abstractРозроблено алгоритм визначення кількості енергії, що переноситься сухою насиченою парою, витрату якої визначають за методом змінного перепаду тиску із застосуванням стандартного еліпсного сопла з малим і великим відносним діаметром. Застосовано рівняння для визначення термодинамічної температури сухої насиченої пари при вимірюванні її абсолютного тиску, або абсолютного тиску при вимірюванні її термодинамічної температури. Отримано нове безітераційне рівняння для розрахунку масової витрати теплового енергоносія. Запропонований метод і рівняння визначення кількості енергії можуть бути застосовані у цифрових пристроях як для технологічного так і комерційного обліку плинних енергоносіїв. Застосування розробленого алгоритму збільшує швидкість розрахунку кількості енергії, що переноситься плинним енергоносієм, за допомогою еліпсного сопла із застосуванням мікропроцесорних контролерів та обчислювачів.
dc.description.abstractThe algorithm for determining the amount of energy transferred by the dry saturated steam has been developed. The steam flow rate is measured by means of the differential pressure method with application of a standard long radius nozzle of a high-ratio type and a low-ratio type. The equations for determining the thermodynamic temperature of dry saturated steam when measuring its absolute pressure was applied together with the equations for determining the absolute pressure of dry saturated steam when measuring its thermodynamic temperature. A new non-iterative equation for calculating the mass flow rate of the heat energy carrier was obtained. The proposed method and equation for determining the amount of energy can be applied in digital devices for both technological and custody transfer metering of fluid energy carriers. Application of the developed algorithm in the microprocessor controllers and calculators provides the increase of computational speed at measurement of the amount of energy transferred by the fluid energy carrier with application of a long radius nozzle.
