Selecting the right gas meter model for accurate flow measurement requires consideration of several factors, including measurement accuracy, measurement range, medium characteristics, environmental conditions, and cost budget. Here are some suggested steps and considerations to help you make the best choice:

Define Measurement Requirements

  • Measurement Range: Determine the range of gas flow that needs to be measured to ensure that the selected phenotype can meet the actual demand. Too wide or too narrow a flow range can lead to inaccurate measurements.
  • Measurement accuracy: According to the requirements of the application scenario for measurement accuracy, select a natural gas meter with appropriate accuracy. High-precision phenotypes are generally suitable for situations where rigorous metrology is required, such as trade settlement or process control.

Consider Medium Characteristics

  • Gas composition: The main component of natural gas is methane, but may contain other impurities. Knowing the specific composition of the gas helps to select the appropriate phenotype to avoid impurity affecting measurement accuracy.
  • Pressure and temperature: The pressure and temperature of natural gas affect its density and flow. Select a phenotype that can adapt to the actual working pressure and temperature to ensure the accuracy of the measurement results.

Assess Environmental Conditions

  • Installation environment: Consider the installation location of the gas meter, space constraints, and whether explosion-proof certification is required. For example, natural gas meters used in flammable and explosive environments need to have corresponding explosion-proof properties.
  • Climatic conditions: Select the appropriate phenotype according to the climatic conditions of the region. For example, gas meters used in extremely cold or hot areas need to be resistant to low or high temperatures.

Consider the Cost Budget

Under the premise of meeting the measurement needs, the appropriate gas meter is selected according to the cost budget. Different models of gas meters can vary greatly in price, so it is necessary to find a balance between performance and price.

Based on the above considerations, the following are some recommended models for natural gas measurement:

ATLQ Gas Waist Wheel (Roots) Flow Meter: Intelligent gas waist wheel (Roots) flowmeter is the ideal instrument for measuring non-corrosive gases such as natural gas, city gas, nitrogen, industrial inert gas.


ATLU Precession Vortex Flow Meter: This flow meter sets flow, temperature, pressure detection function in one, and can automatically compensate temperature, pressure, compression factor, is the ideal instrument for gas measurement in petroleum, chemical, electric power, metallurgy and other industries.


ATWG Gas Turbine Flow Meter: mainly used for the flow measurement of natural gas, air, nitrogen and other medium fluids in industrial pipelines, and is almost unaffected by fluid density, pressure, temperature, viscosity and other parameters when measuring the volume flow under working conditions.

Summary and Suggestion

When selecting a suitable gas meter model, factors such as measurement requirements, medium characteristics, environmental conditions and cost budget should be taken into account. It is recommended to communicate with a professional instrument supplier or manufacturer for more detailed product information and technical support. At the same time, regular maintenance and calibration of the gas meter is also an important measure to ensure the accuracy of the measurement.
