<p>There is provided a method of calibrating a measurement system for measuring a position (h) of a meniscus of a liquid fuel included within a marine fuel tank and therefrom generating a corresponding content signal indicative of a proportion of the tank filled with fuel. The method includes steps of: (a) from a first time instance when the tank is substantially empty, filling during a calibration phase the tank with the fuel at a substantially constant rate whilst simultaneously recording corresponding values (h(t)) of a meniscus position indicative signal generated by the measurement system; (b) at a second time instance after said first time instance, terminating filling of the tank with fuel when the position indicative signal corresponds to the tank being substantially filled with fuel; and (c) subsequently, after the calibration phase, applying signal processing to the position indicative signal to generate the content signal indicative of the proportion of the tank filled with fuel, the signal processing accounting for the tank during the calibration phase being filled at the substantially constant rate.</p> |
