Due to its cleanliness and high combustion value, natural gas has a wide range of applications in modern urban life, industrial production, hotels, restaurants, and other industries. There are many types of flow meters that can measure natural gas, and the appropriate type of natural gas flow meter can generally be selected according to the following principles.

1. The flow meters used for settlement with natural gas companies are generally Roots flow meters and gas turbine flow meters, and there are also options for vortex flow meters. However, in most cases, natural gas companies specify flow meters, and there are not many cases of self selection;

2. Household natural gas meters generally use membrane type mechanical meters, and in most cases, natural gas companies install them in advance;

3. In addition to Roots flow meters and gas turbine flow meters, the natural gas flow meters used inside the factory can also choose spiral vortex flow meters and integrated temperature and pressure compensation vortex street flow meters;

4. Gas ultrasonic flow meters are also used to measure various gases such as dirt, corrosion, wet saturation, viscosity, and high and low temperatures.

In addition to knowing the pipe diameter, measuring natural gas flow also requires knowing the flow rate size (distinguishing between standard flow rate and operating flow rate) and accurate operating pressure and temperature, especially the accuracy of operating pressure, which has a significant impact on the measurement results.
