Implementation method of capacitance liquid level sensor with high accuracy, self-adaptation performance and large measurement range

The invention provides an implementation method of a capacitance liquid level sensor with high accuracy, self-adaptation performance and a large measurement range. Embedded hardware and software application system implementation serves as the basis, a multi-segment mechanical organization structure is adopted, a measurement processing algorithm model for rough judgment, medium, temperature and humidity change compensation and accurate calculation is established on the comparison calculation basis, the purpose of the 0.01mm liquid level measurement accuracy is achieved, self-adaptation of changes of measurement media, the environmental temperature and the environmental humidity is achieved, the measurement range can be several meters through the multi-segment mechanical organization structure, and the strong guarantee is provided for accurate detection of the oil level of oil tanks of automobiles/ships/aircrafts/agricultural implements/military movement carriers, the oil level of liquid fuel storage tanks and the water level of boilers.
