Gas appliances and natural gas canisters can be used to measure natural gas emissions in the US.
Natural gas measurement can be done from an internal gas line, or from a device installed in a gas pipe.
Natural gas measurement equipment, such as the Natural Gas Measurement System (NGMS) and the Natural Instrument for Gas and Natural Gas Emissions (NIGE), can be purchased by customers as a standalone unit, or as a kit.
The NRG, an energy efficiency company, supplies equipment to retailers such as Target and Costco that can measure natural-gas emissions in homes and businesses.
The company says it sells more than 15 million units each year.
In Australia, Natural Gas Appliances and Gas Appliance Measurement Systems (NGMEMS) are widely available in retail outlets and residential and commercial customers.
Natural Gas Measurements can be made using a portable device with an external gas gauge, which measures the level of natural gas in the air at the point of use.
This equipment is known as a gas gauge and is commonly used in gas stations and home appliances.
In the US, natural gas meters can be bought in large quantities from gas companies and other retailers.
The most popular models include the Green Gas Meter, the Naturalgas Meter Plus, the Gas Meter and the Gas Meter Plus II.
These models are used in large retail gas stations to monitor gas consumption.
The US Environmental Protection Agency (EPA) has issued guidelines for how natural gas companies should measure their natural gas operations.
These guidelines allow for a maximum natural gas consumption of 20 cubic feet per hour (CFEH/hr) for the average household, up to 40 CFEH for businesses, and up to 80 CFEHR for households.
In addition, the US EPA recommends that natural gas operators provide customers with a way to record and track their CO2 emissions and provide customers a way for them to track their carbon footprints, or carbon dioxide emissions from the gas they use.
