Abstract: A digital field-induction water-level intelligent sensing system is provided. The digitalized intelligent field-induction field technology is utilized in the sensing system, thus the problem of water scale formation on the water-level sensors when applied in the severe environment and the problem of sensing system failure easily happening in the high temperature and high humidity environment are solved. The application of the field-induction technology enables the sensing system to detect the water level without electrical connection or mechanical connection, thus the problems of the sensor failure or inaccurate water-level detection caused by the water scale formation are avoided.
