PURPOSE: A device for indicating the remaining amount of a methanol fuel tank is provided to efficiently measure the remaining amount of methanol in the fuel tank and prevent vaporization of methanol through non-contact measurement of methanol fuel. CONSTITUTION: A device(100) for indicating the remaining amount of a methanol fuel tank(10) comprises the fuel tank having a first chamber(13) in which fuel is received, and a second chamber(15) in which a coolant(17) to be pressurized by the weight of fuel(11) is received; a temperature sensor(19) installed to the second chamber to sense the temperature of the coolant; a tube member(20) communicating with the second chamber; a pressure sensor(30) mounted to the tube member to measure the pressure of the coolant; a control unit(40) deriving and indicating the remaining amount of fuel by the weight of the fuel in the first chamber by the sensed pressure of the coolant; a pump member mounted to the tube member to circulate the coolant; and a cooling fan installed to the tube member.
