Your inner tank should have arms which touch the outer tank, to prevent relative movement of the inner tank, with respect to the outer tank.
Finally done a full sketch of my idea. The Z axis is drip monitored in exactly the same way as the original Peachy. The two cylinders nest to form an hydraulic cylinder. The saline is forced back into the same tank and therefore the level never changes as the platform drops.3d.jpg
