This tank device includes a fuel gas tank that stores fuel gas supplied to a gas consuming device, a first pressure sensor that detects a gas pressure when the fuel gas is filled into the fuel gas tank, and the fuel gas tank A second pressure sensor that detects the gas pressure of the fuel gas supplied to the gas consuming device in a gas supply line from the fuel gas tank to the gas consuming device, and a sensor output that determines an abnormality in the output of the first and second pressure sensors It has a judgment part. The sensor output determination unit includes a detection gas pressure of the first pressure sensor when gas is filled into the fuel gas tank, and a fuel gas is first supplied from the fuel gas tank to the gas consuming device after the gas filling is completed. When the gas pressure difference of the detected gas pressure of the second pressure sensor is obtained, and when the gas pressure difference falls within a predetermined threshold range, it is determined that there is no output abnormality in either of the first and second pressure sensors, and the When the gas pressure difference does not fall within the predetermined threshold range, it is determined that there is an output abnormality in either of the first and second pressure sensors. |
