Water level sensors are commonly used in industry. Some of the sensors are of capacitive nature. It is important to predict water level accurately. That’s why a good sensor model is needed. The finite difference (FD) method is a simple and commonly used numerical method to solve differential equations. In literature, to the best of our knowledge, the finite difference method has not been used to design such a capacitive sensor yet. In this study, the FD method is used to solve Laplace equation in two dimensions. The variation of the sensor capacitance is obtained as a function of water level. The calculation method given here can be used as a starting point for designing such and similar sensors.
