Contact type electronic water gauge with high-precision measurement

The utility model discloses a contact type electronic water gauge with high-precision measurement, which comprises a high-speed analog switch, single-section measuring structures and an MCU (Microprogrammed Control Unit) processing module, the high-speed analog switch is respectively connected with the single-section measuring structures through electric signals, the single-section measuring structures are electrically connected one by one from top to bottom, and the MCU processing module is electrically connected with the high-speed analog switch. According to the utility model, the high-speed analog switch adopts a 74hc4067 high-speed analog switch to switch electrodes, whether the electrodes are in contact with water or not is measured according to the weak conductivity principle of water, and whether the electrodes are in contact with the water or not is judged according to the weak conductivity principle of the water. The single-section measuring structure measures the water level of an electrode accordi
