With all the computing power available in the LY, it is possible to characterize the tank such
that this height measurement converts to a precise volume measurement(V ), which may then be
converted into a total mass (m) measurement based on the mass density of the liquid (ρ) and the
acceleration of gravity (g). First, the computer calculates mass density based on the proportionality between mass and weight (shown here starting with the equivalence between the two forms of the hydrostatic pressure formula):
