Abstract :
The ultrasonic flow measurement system measures the propagation time difference in opposite directions on a fixed way to calculate the flow speed. The system uses chip C8051F020 as the core, which has powerful functions in controlling, sampling and calculating, and can accomplish the control of ultrasonic impulse receiving/sending, time difference judgment and data process. The measurement system improves the sensitivity and reliability greatly. After the principle and method of the measurement system are analyzed, the design ideas and hardware circuit of the system are provided in the paper. The measurement system can be widely used in industry, agriculture and environment observation fields.
