“…Continuous measurements are divided into the following types: buoyancy, weight measurement, pressure, capacitance, ultrasound, and radiation. Discontinuous measurements are divided into the following types: conductivity, heat transfer, capacitance, optical, ultrasound, and microwave [1][2][3]. Some sensors used for measuring liquid level are summarized in Table 1.…”

This research proposes an algorithm using a process of integrating data from multiple sensors to measure the liquid capacity in real time regardless of the position of the liquid tank. The algorithm for measuring the capacity was created with a complementary filter using a Kalman filter in order to revise the level sensor data and IMU sensor data. The measuring precision of the proposed algorithm was assessed through repetitive experiments by varying the liquid capacity and the rotation angle of the liquid tank. The measurements of the capacity within the liquid tank were precise, even when the liquid tank was rotated. Using the proposed algorithm, one can obtain highly precise measurements, and it is affordable since an existing level sensor is used.
