| Abstract: | Taking CPLD whose type is EPM7064AE as a core device of celoccity measurement,as a microprocessor,MSP430FW427 microcotroller is used to design a ultrasonic flowmeter based on the lower power consumption technology.The hardware circuit workflow of the ultrasonic flowmeter is introduced.Through using the lower power consumption technology,the dynamic working current of the meter reaches to 12μA,the static current reaches to 2~3μA,the battery life is more than 10 years.The ultrasonic flowmeter has some advantages,such as small starting flow,lower pressure loss,lower power consumption,reliable work and fully function etc.It has a good application prospect. |
| Keywords: | ultrasonic flowmeter CPLD EPM7064AE MSP430FW427 low power consumption |
