Abstract：Ultrasonic flowmeter is through the test fluid flow of the ultrasonic bunch of (or ultrasonic pulse) role to measure flow of meter, the purpose is to solve some difficult problems of measurement. Meaning is that flow meters will be able to adapt the industrial field environment, more convenient, economy, measurement accuracy, and itself does not damage easily, low power consumption, high reliability. Such products for the domestic and international advanced level, and can be widely used in petroleum, chemical industry, metallurgy, electric power, water supply and drainage, etc.Research the system of ultrasonic flowmeter. Based on the practical reasons and designs a portable ultrasonic flowmeter system based on singlechip puter
