Abstract
In a gas supply system, a control portion acquires a first temperature and a first pressure of a gas in a fuel tank, and a first output signal value of a pressure sensor corresponding to the first pressure before gas supply, acquires a first amount of the gas in the fuel tank using a fuel tank volume, the first temperature, and the first pressure, acquires a second amount after gas supply, through integration of a measurement value obtained by a flowmeter during gas supply, acquires a second temperature, a second pressure, and a second output signal value corresponding to the second pressure after gas supply, calculates a third pressure using the fuel tank volume, the second amount, and the second temperature, and corrects a relationship between an output signal and the pressure using the first pressure, the first output signal value, the third pressure, and the second output signal value.
