The issue of adjusting the float with water

Adjust the float using water; but what if the density of the medium being measured is greater than that of water? How should it be adjusted in that case? Because even when the float tank is filled with water, it cannot output 20MA. So what method should be used?

There are original example questions on the instrument technician test question set
Perform the conversion, and then verify the resulting current value；
