The utility model discloses a dynamic compensation type thermal gas flowmeter in the technical field of gas flowmeters, which comprises a runner pipe, two ends of the runner pipe are respectively connected with an external gas flowing pipeline, the surface of the runner pipe is provided with a surface-mounted thermometer, the surface-mounted thermometer detects the temperature of gas in the runner pipe, and the temperature of the gas in the runner pipe is measured by the surface-mounted thermometer. And the top of the circulating pipe is connected with a first temperature detection structure through a top pipe, a temperature compensation assembly is installed at the top of the first temperature detection structure and comprises an outer pipe, and the interior of the outer pipe is coaxially connected with an inner pipe. By dynamically compensating the increased or lost heat of the flow meter in the heat exchange process, the gas flow rate measurement accuracy of the flow meter can be improved, the error betwee
