Description: Traditional level measurement system accuracy, anti-jamming capability, contact, on a radar principle of the development of digital liquid level measurement system. The system uses the FM measurement, frequency measurement with C8051F020 MCU as the core of the module. Used the autocorrelation function of signal filtering Fast Fourier Transform (FFT) algorithm, frequency-domain analysis frequency shift on the frequency refinement, the final height of the level. The system has a strong ability to adapt and improve the interface, in measured with satisfactory precision.
