A piston of an apparatus is movable within a cavity between a first position wherein a pressure port is in fluid communication with the first fluid chamber and a second position wherein the pressure port is in fluid communication with the second fluid chamber. In further examples, apparatus comprise an expansion chamber that is isolated from the first fluid chamber in a first condition and the expansion chamber is in fluid communication with the first fluid chamber in a second condition. In further examples, methods of operating an apparatus include the step (I) of applying fluid pressure to at least one of the first fluid chamber and the second fluid chamber, and the step (II) of determining a position of the piston within the cavity based on the applied fluid pressure.
