| Abstract: | A low power vortex flowmeter signal processing system is presented,which is based on double-core technique combined digital signal processor(DSP) with microcontroller(MSP430).The relaxing notch periodogram algorithm processes the sensor signal's frequency,and then the precise vortex frequency and flow can be obtained.Experiment results show that this system has high anti-interference,extended measuring range,and real time data processing abilities,and will have a bright future. |
