【Abstract】 The detecting principle, the device and design of the hardware of the multi-function ultrasonic flow-detecting system are introduced in this paper. The detecting circuit and the data switching between double MCU are presented,the program flow chart and anti-interference methods are given,and the primary origin of the measurement error is discussed. The system has many real-time functions,such as flow detection, keyboard control,LCD show, miniature prints and communication with the PC. It acquires the good result at actual application.更多还原
