| description | The invention discloses a gas turbine flowmeter fault diagnosis method and system, and particularly relates to the technical field of gas turbine flowmeter diagnosis. Firstly, whether the temperature, detected in real time, of a gas flowing area in the flowmeter system is abnormal or not is judged; then, when the detected real-time temperature is in an abnormal state, the accuracy of the output value of the sensor is evaluated; analyzing the abnormal degree of the turbine blade impacted by the airflow under different pressure conditions, and evaluating the response stability of the turbine under different flow speeds; thirdly, comprehensively analyzing the accuracy of output values of the sensors and the response stability of the turbine at different flow speeds, evaluating the overall performance of the gas turbine flowmeter, dividing the overall performance of the gas turbine flowmeter, and finally analyzing the overall performance change condition of the gas turbine flowmeter within a period of time.
