Design of Liquid Flow Measurement System Based on FPGA
Traditional liquid flow detection methods have shortcomings such as small measuring range,low accuracy,poor en-vironmental adaptability,and great influence by temperature.They can not measure the target liquid flow well.At the same time,due to the shortcomings of high cost and easy structural wear,they will also cause economic losses.Aiming at the above problems,a liquid flow measurement system based on FPGA is proposed,which takes the time difference method as the theory,FPGA as the control core and MS1022 as the measurement core.It improves the shortcomings of time difference method and eliminates the influ-ence of temperature on measurement.The test results show that the system error is less than 2%,which has good reliability and sta-bility and can be applied in related fields.
