The utility model provides an automatic oiling machine capacity wireless calibrating device for a vacuum heat-insulated standard metal measuring vessel and belongs to the technical field of capacity standard calibrating devices. The automatic oiling machine capacity wireless calibrating device aims at solving the problems that an existing oiling machine capacity calibrating device for the standard metal measuring vessel transmits data through a communication cable and the communicated cable is made of materials which are prone to loss. A data acquisition wireless transmitter adopted by the automatic oiling machine capacity wireless calibrating device is connected to a vacuum heat-insulated standard metal measuring vessel body. A data acquisition circuit and a wireless transmitting module are arranged in a transmitter anti-explosion shell in a sealed mode. The data acquisition circuit is connected with a nozzle temperature sensor and a measuring vessel body temperature sensor which are inserted in a nozzle out
