【Abstract】 Abstract Using ultrasonic flowmeter with single board computer to meas- urement makes it is possible to omit oscilloscope and numeric frequency meter, and to realize automation of measurement and data processing. The system is simple in structure, convenient in operation, high in precision and large in anti-interference, etc. The principle of system measurement, performance index and hardware construction are described simply, and the block diagram of main program is given.更多还原
