The invention relates to a refueling detection device, a gas Roots flowmeter and a refueling detection method. The gas Roots flowmeter solves the problems that in the prior art, when a gas Roots flowmeter is used, due to the fact that maintenance is not timely, abrasion of a shaft and a bearing is often caused by lack and deterioration of lubricating oil, the metering precision is affected, and even the phenomenon of jamming occurs. The refueling detection device comprises a control module, an oil level detection infrared receiving tube, an oil level detection infrared transmitting tube, an oil quality detection infrared receiving tube and an oil quality detection infrared transmitting tube which are connected with the control module, and a transmission and reflection piece, a refraction and reflection piece and a sheath which are sequentially connected from left to right; the oil level and the oil quality are detected through the difference between the light signal information emitted by the infrared rays an
