摘　　要：针对涡街流量计低流速的信号噪声问题,介绍基于MSP430数字涡街流量计的实验系统,探讨、研究噪声信号的处理。采用精度较高的称重法在流量实验标准装置上对数字涡街流量计进行标定。实验结果表明,运用MSP430功能强大的微处理器及高速运算能力,有效地扩大涡街的量程比,实现对涡街流量计的信号分析、处理,提高对噪声的抗干扰能力。Aiming at the low flow signal noise problems of the vortex flowmeter,the MSP430 digital vortex flowmeter-based experimental system and the noise signal processing were studied,and a weighing method of high precision was employed to calibrate digital vortex flowmeter.The experimental results show that the MSP430＇s powerful microprocessor and high-speed computing capability can expand the vortex ratio range effectively,improve the anti-jamming capability and have vortex flowmeter＇s signal analyzed.
