| Zusammenfassung: | The present invention provides a temperature and pressure compensation calculation-based gas meter metering method. With the method adopted, the influence of temperature and pressure can be substantially eliminated, so that the metering of a gas meter can be accurately and efficiently realized. The method includes the following steps that: (1) a gas meter of which the metering is normal and a temperature and pressure assembly are selected, data can be transmitted between the gas meter and the temperature and pressure assembly through an integrated circuit bus; and (2) the gas meter sends a reset command to the temperature and pressure assembly, so that six regression coefficients returned by the temperature and pressure assembly to the gas meter are obtained. According to the temperature and pressure compensation calculation-based gas meter metering method of the invention, common membrane type gas meter metering and electronic compensation are combined, so that the metering of the gasmeter can be realized ba |
