Any float-level system will not be linear unless the tank is square-dimensioned (not necessarily square-shaped). This doesn't mean that the float gauge won't be useful, just not gauge-accurate. You will have to employ Kentucky calibration (bastardization of a shooting term, Kentucky windage). What would be useful in this case would be to fill your empty tank with a known quantity of liquid, and mark your gauge's face accordingly.
