Yes but they are governed by the length of the probe.
A major problem is determining just where you want the readings to be accurate.
A square or rectangle tank is pretty easy to get correct and calibrate the sending unit, the volume varies proportionally with the level of the fuel.
A belly tank on the other hand gives the impression the lower the fuel level is the more quickly it runs out of fuel but seems to not consume as much when fully loaded.
Or am I not reading your questions correctly?
