Research of Super-Size Intelligence Flow Measurement System


Article Preview

In this paper, we study a kind of intelligent and high-accuracy flow measurement system, which is a type of venturi tube flowmeter that surpassed the international standard ISO5167. This paper analyzes the characteristics of the super-size flow measurement in the water transportation and industrial projects, and the choice for suitable flow meters. We study the practical compensation technology for discharging coefficient “C” of the international-standard-exceeding venturi tube, and puts forward water calibration method for venturi tube, and design the intelligent and high-accuracy flow metering system based on computer technology. Furthermore, this paper analyzes the calibration data of water flow, and propose the segment and compensation method for discharging coefficient “C” practically. We solved the limitations of the international-standard-exceeding venturi tubes, and effectively improved the accuracy and range of the flow measurement system.
