A self-adjusting gear system (180) for an instrument (110,130,150) for a flow meter (100) can automatically adjust in response to the rotational dire ction of the drive shaft (135), thereby permitting the instrument device (11 0,130,150) to perform its intended measurement function regardless of the fl uid flow direction through the flow meter. In one example, the instrument ma y comprise a corrector instrument that includes a counter (160,170).
