An inexpensive refueling machine having high safety is disclosed. The refueling machine comprises a nozzle box disposed at a place which is likely to be exposed to an explosive atmosphere and having a valve for controlling the start and stop of refueling to a nozzle, and a console box disposed at a place which is unlikely to be exposed to an explosive atmosphere and having a control unit for controlling the operation of the valve. Electric equipment is not contained in the nozzle box but in the console box. The nozzle box and the console box are interconnected by pipes which pass a compressed air for controlling the operation of the valve and an optical fiber which transmits an output of flowmeter and signals of fuel sensor probe. The refueling machine may have means for distinguishing a kind of fuel.
