A 0-100 foot tank with a specific gravity of 0.8 has the highest measurable level. What is that level?

When level measurements are tied to hydrostatic pressure or buoyancy, the liquid’s density (specific gravity) affects how the signal maps to a physical height. Most level devices are calibrated for water (specific gravity 1). If the liquid has a lower density, like 0.8, the same sensing signal corresponds to a shorter vertical distance on the scale. So, in a 0–100 ft tank, a liquid with SG 0.8 will reach the maximum indicated level at about 0.8 of the full scale. That gives a highest measurable level of 100 ft × 0.8 = 80 ft.
