- Scope
- This standard stipulates that the maximum working pressure shall not exceed 50 kPa, the maximum flow rate shall not exceed 160 m3/h, the minimum working environment temperature range shall be -10 °C to + 40 °C, and the working medium temperature range shall not be less than 40 K. The technical requirements and test methods for the structure, performance, safety and other aspects of the 1.5-level diaphragm gas meter with pipe or single pipe joint (hereinafter referred to as gas meter). This standard applies to gas meters installed in closed places (indoors or outdoors with protective measures) or open places (outdoors without any protective measures) with or without slight vibration, shock, condensed water and electromagnetic interference [including the installation of electronic auxiliary device (see appendix C), gas meter with built-in mechanical gas temperature conversion device (see appendix D)]. Unless otherwise specified, the pressure mentioned in this standard refers to relative atmospheric pressure (gauge pressure).
