摘要
针对目前流量测量仪表中普通涡街流量计在低流速和振动环境下性能的不足,研制出一款数字滤波智能型涡街流量计,它基于MSP430单片机和DSP的双核处理平台,采用双通道处理方式,将频谱分析功能和计频功能有机地结合,有效地解决了上述问题。具有抗震性好、量程宽、性能稳定等优点。
The ordinary vortex flowmeter is not suitable for the measuring in the low-moving and vibrant environment. The digital filering vortex flowmeter is based on MSP430 singlechip and DSP double-processor platform. The combining of frequency spectrum analysis and frequency-measuring solves availably the above-mentioned problems.The flowmeter is of many advantages in vibrant environment,wide range and stability,and so on.
