    Flow meters are required to be calibrated regularly. How often do hydrogen flow meters need to be calibrated?

    For test station operation, hydrogen mass flow meters are generally calibrated annually. For hydrogen refueling stations it may be more often (there may be regulatory requirements for how often the MFMs need to be calibrated – region dependent).
