dc.description.abstractРозроблено нове рівняння та алгоритм для безітераційного розрахунку витрат плинного енергоносія для витратоміра змінного перепаду тиску на основі еліпсного сопла. Це рівняння містить у неявному вигляді три вкладені ітераційні цикли обчислення витрат. За результатами порівняння значень витрат, отриманих за розробленим безітераційним алгоритмом, зі значеннями витрат, одержаними за стандартизованим ітераційним алгоритмом, встановлено, що запропонований безітераційний алгоритм забезпечує точність обчислення витрат, визначену вимогами стандарту ДСТУ ГОСТ 8.586.5:2009. Отже, запропоновані рівняння та алгоритм обчислення витрати можуть застосовуватись у витратомірах на основі стандартного еліпсного сопла як для технологічного, так і для комерційного обліку плинних енергоносіїв. Використання розробленого алгоритму дає можливість пришвидшити розрахунок витрати енергоносія за допомогою мікропроцесорних контролерів.
dc.description.abstractNew equation and algorithm are developed for non-iterative calculating flowrate of fluid energy carrier for pressure differential flowmeter based on long radius nozzle. This equation implicitly contains three build-in iterative cycles for calculating flowrate. According to the results of comparing the flowrate values obtained by developed non-iterative algorithm to the flowrate values by standard iterative algorithm, the authors found that the developed non-iterative algorithm ensures the accuracy of flowrate calculation specified by the requirements of DSTU GOST 8.586.5:2009. Therefore, the proposed equation and algorithm for calculating flowrate can be used for flowmeters based on standard long radius nozzle for both technological and commercial metering flowrate of fluid energy carriers. Application of the developed algorithm makes it possible to increase the speed of calculating flowrate of fluid energy carriers by means of microprocessor controllers.
