摘要
实验结果表明,新型的磁致伸缩液位仪具有较高的测量精度,克服了传统的由于量程原因带来的信号幅度变化而对测量结果的影响。利用FPGA的高频计数方式测量激励和检测信号的时间差,降低了系统的测量误差。该液位仪能广泛应用于机场等需要高精度、高可靠性的液位测定领域,具有相当好的应用前景和市场前景。
The experimental results show that novel magnetostriction liquid-level sensor is high precision meter, the influence of variable amplitude is overcome. The measurement error is reduced by the the field programmable gate array using the high frequency counter to calculate the difference of invigorative and response pulse.
