| Summary: | Measurement of the water level, derived from inherent problems inherent in the nature of the liquid, represents one of the most recurring challenges in both an industrial and a residential context. In this work, a real-time water level measurement system using an optical-magnetic sensor with high linearity, low cost, high reproducibility, and easy installation is proposed. Firstly, mathematical modeling of the water level measurement in a tank using differential equations is described. This system comprises a printed circuit board (PCB), a novel float mechanism, an optical sensor, a microcontroller, and a visualization stage. The proposed float system solves the common problems of corrosion and calcareous sinter, optimizing the functionality of the device for long-term applications. The microcontroller is used to calculate the distance between a reflective cross section and the optical transmitter of the float mechanism correlated to the water level. Certainly, the proposed design offers a key advantage; it prevents direct contact between water and vapor with the sensor device. This separation helps maintain sensor accuracy and longevity. Ten experiments were carried out to measure the water level in a tank manually and automatically and were compared with the mathematical calculation. The preliminary results of the proposed system have an approximate difference of 5% with respect to the analytical calculation.
