Beschreibung
Zusammenfassung:	The gas meter comprises a shell, the shell is provided with a gas inlet and a gas outlet, and the gas inlet of the shell is provided with a valve; the metering device is arranged in the shell, and gas can be discharged from the gas outlet through the metering device; a first absolute pressure sensor is arranged in the shell; a second absolute pressure sensor is arranged outside the shell and is used for measuring atmospheric pressure; and the control module is in signal connection with the first absolute pressure sensor, the second absolute pressure sensor and the valve, and the control module can control opening and closing of the valve. According to the gas meter provided by the technical scheme, the first absolute pressure sensor is arranged in the shell, the first absolute pressure sensor can measure the pressure of gas in the shell, the second absolute pressure sensor can measure the atmospheric pressure of the gas meter, and calculation is carried out through the measured values of the two absolute pres
