A computer (20) adapted to communicate with a measuring apparatus (12) for receiving liquid level measurements and delivering a calibrated fuel quantity output (24) to a readout instrument (14). The computer (20) has an input interface (34) with a first input (22A) for accepting a first liquid level measurement signal from said measuring apparatus (12). A first bias circuit (30A) provides an adjustable offset bias to minimize voltage errors due to input bias current received in the first liquid level measurement signal (26A). Computer(20) also has a calibrating circuit (36) for calibrating the first liquid level measurement signal to provide a calibrated fuel quantity output signal (24) that can be read by readout instrument (14) through output interface (42).
