Abstract: The present invention discloses an online method for metering performance of a diaphragm gas meter. A magnetic turntable in an electromechanical conversion device is reasonably segment and motion information of each segment is recorded and analyzed. Every time when the diaphragm gas meter discharges gas of a rotary volume, a rotating shaft of a meter core rotates a circle. The magnetic turntable is meshed with a driving gear output by the rotating shaft in the meter or output by the rotating shaft outside the meter to ensure that the magnetic turntable rotates a circle every time when the diaphragm gas meter discharges a rotary volume. The present invention is significant for error management of the gas meter and intelligent control and gas utilization safety management of a gas user.
