A formula is written in the liquid level detection system, and according to the capacitance principle, when the distance between the polar plates, or the opposite area, or the dielectric mass is changed, the capacitance capacity is changed. By measuring the capacitance change, the dielectric change of the determined capacitor with the positive area of the plate and the distance between the plates can be calculated. Experiments show that after the distance between the plates and the specific area are determined, the capacitance change rate and the liquid level between the plates are in a certain proportional relation.
