- Scope
- This standard applies to gas ultrasonic flowmeters using the propagation time difference method, with a diameter equal to or greater than 100 mm and a pressure not lower than 0.1 Mpa (gauge pressure). It is generally used for natural gas flow measurement in production equipment, gas transmission pipelines, storage facilities, gas distribution systems and user metering systems whose temperament meets the provisions of Article 5.1 of this standard. The standard reference conditions for natural gas volume calculation used in this standard are: the pressure is 0.101325 Mpa (absolute pressure), and the temperature is 20°C (293.15 K). Other reference conditions stipulated in the contract may also be adopted.
