This ST code is a simple formula for level in a horizontal tank, note: this was done in Mitsubishi so some functions require to have the result in the function brackets so were done seperately & the result placed in the formula, this could easily be made into a function block where only the length, radius, actual level & eliptical type ends (if required) would be passed as input variables & the resulting level/weight or volume as an output variable, the others would be local variables.
