Abstract
A measurement system for determining a liquid fill level of a tank, including a floating sensor configured to float on the surface of a liquid contained in the tank, at least three reference sensors mounted at a hull of the tank in a spatially fixed arrangement, and a control device to control the floating sensor and the reference sensors, wherein at least one of the floating sensor and the reference sensors can emit an acoustic signal to the remaining sensors, wherein the remaining sensors can receive the emitted acoustic signal, and wherein the control device is configured to determine signal travelling times of the acoustic signal from the emitting sensor to the receiving sensor, to compute a spatial position of the floating sensor with respect to the reference sensors from the signal travelling times, and to determine the liquid fill level using the computed spatial position of the floating sensor.
