Abstract
The ultrasonic flowmeter designed in this paper uses improved time difference method to measure the flow velocity, uses MSP430 as microprocessor. The flow velocity measurement equipment of the ultrasonic flowmeter is based on CPLD(EPM7064AE). The results of the experiments show that the ultrasonic flowmeter has many advantages such as low starting flow, small pressure loss, low consume, operation reliable, fully functional and so on. It has good potential application of market.
