| Abstract: | On the development of a liquid density tester, three anti-interference methods, the elimination of zero point error and floating, the average of wave intensity and the ratio of wave intensities are employed in data collection and processing by one-chip processor. These methods have effectively eliminated noise interference, and eusured the stable and accurote operation under extremely abnormal condition. |
