摘要
传统的液体流量检测方法有着测量范围小、精度低、环境适应性较差、受温度影响较大等缺点,不能很好地测量目标液体的流量,同时由于成本高、结构易磨损等缺点,也会造成经济损失.针对以上问题,提出了以时差法为理论、FP-GA为控制核心、MS1022为测量核心的基于FPGA的液体流量测量系统,改进了时差法的不足,消除了温度对测量的影响.测试结果表明,系统误差小于2%,具有良好的可靠性和稳定性,可应用于相关领域中.
Abstract
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.
