Liquid-level sensing based on capacitive sensors comes with its own challenges. It's like absolute capacitance sensing. Unlike touch detection, the absolute value of the liquid level needs to be measured.. Furthermore, environmental factors such as temperature and the presence of conductive objects can affect sensing ac-curacy. The common factors that impact liquid-level sensing are as follows: 1.Temperature drift 2.Tank thickness 3.Liquid viscosity 4.Liquid salt concentration 5.Conductive objects 6.Air gap between sensors and tank
