The invention discloses a meter body gas rectification structure which comprises a rectification cover and a measuring flow channel, and the rectification cover is arranged on the periphery of the end portion of the measuring flow channel in a covering mode. The third rectifying unit is detachably connected to the side, close to the fairing, of the measuring flow channel, the first rectifying unit is provided with a first outer cylinder matched with a flow meter in shape and a plurality of groups of rectifying guide plates distributed on the inner circumference of the first outer cylinder, and each group of rectifying guide plates are obliquely arranged; and the projection surfaces of the two adjacent groups of rectification guide plates are partially overlapped. According to the invention, the fairing is arranged in front of the measuring flow channel in the meter body, the medium flowing in from the front part is blocked, the flowing path of the medium is changed, the medium can be dispersed at the periphery of the measuring flow channel along the periphery of the fairing, the medium cannot directly enter an inlet of the measuring flow channel, and the medium is rewound to the inner side of the fairing in the meter body, so that the measurement accuracy is improved. And the gas flows along a gap / cavity formed between the fairing and the measuring flow channel and then enters the measuring flow channel through the third rectifying unit.
