Residential Gas Meter and Various Natural Gas Meter Types
There are various natural gas meter types used in the natural gas industry, each having its benefits and purpose. These different types of meters are either inferential meters or positive displacement meters. The main four types are diaphragm meters, orifice meters, rotary meters, and turbine meters.
Natural gas meters have been used since the infancy of gas distribution; whether at a high-pressure high-volume natural gas meter station or a residential house, metering gas flow is essential.
Residential Gas Meter – Positive Displacement Type
Other Gas Meters
Other gas meters which measure volume for residential, commercial or industrial applications are:
Ultrasonic Flow meters measure the difference in transit time of pulses that travel from a downstream transducer to the upstream transducer, compared to the time from the upstream sensor back to the downstream transducer. This style of the meter is extremely accurate, has a high turndown ratio and excellent rangeability, but it is costly. Ultrasonic meters are usually used at pipeline meter stations in high-flow and high-pressure applications where the slightest inaccuracy can negatively impact the bottom line.
Coriolis meters provide a direct mass flow measurement based upon the deflection force of the fluid moving through a vibrating tube. These meters are very accurate with high turndown capabilities and are independent of fluid properties. They are also very expensive to purchase and install and are not suitable for larger pipe sizes.
Gas meters measure gas volume; though they do not take into account the quality of the gas which impacts the heat value and is subsequently adjusted in the billing cycle, and known as the therm value. Pressure and temperature compensation are required to convert gas volume to thermal energy. At times electronic correction is also needed.
