| Abstract: | A new time-difference ultrasonic flow detection system was designed.A dual-channels data-collecting system at a high-speed of 40MS/s was constructed on the foundation of XC3S200.And high-powered DSP TMS320VC5509 was used to real-time process digital signals.Compared with traditional ultrasonic flowmeter,the system overcame the disadvantages of low precision,no measuring in small diameter and low flow rates.It improved the precision and resolution.This system had the specialty in high anti-jamming,working stability and credibility,high precision,high real time performance,low power consumption and so on. |
