you forgot to calculate everything
it looks like you regarded as negligable the energy to move your piston which float or sink!
no !
it will take the energy to push the piston and increase the volume at the bottom, or the pressure is higher than the top
conclusion the energy to move the piston is exactly what you would get your machine without loss
if the flip of your float gives enough energy to move the piston, this energy is taken mechanically on the rotation of your machine: even if there is no direct mechanical liason: benefit = loss
the perpetual motion machine are all of the same kind: just complicated enough to hide a mistake to believe
