An amount Y of liquid hydrogen that has passed through a first valve and has been volatilized during a predetermined time after first and second valves are opened is calculated by using a pressure Pin an internal space of a liquid hydrogen tank measured before the two valves are opened, a pressure Pin the internal space measured after the lapse of the predetermined time since the two valves are opened, and an amount X of the gaseous hydrogen that has passed through the second valve during the predetermined time. A fluid level H of the liquid hydrogen in the liquid hydrogen tank after the lapse of the predetermined time since the two valves are opened is calculated by using a expression showing a relationship between the H and an amount Yof the liquid hydrogen that passes through the first valve and drops therefrom, and the Y.
