Economy Value of High Precision Ultrasound Flowmeter

Abstract

In order to improve the measurement accuracy of intelligent water meter, a high precision ultrasonic flowmeter is designed. The device integrates the functions of CPU, DSP and FPGA on one chip to complete the timing function, which effectively improves the integration and stability of the system. The system uses time difference method to measure liquid velocity, and uses DSP Slices of Xilinx Corporation to complete smoothing filter function. The measurement accuracy is high and has a good application prospect.
