How is gas flow measured

Web27 dec. 2024 · Natural gas is a fossil fuel energy source. Natural gas contains many different compounds. The largest component of natural gas is methane, a compound with one carbon atom and four hydrogen atoms (CH 4 ). Natural gas also contains smaller amounts of natural gas liquids (NGLs, which are also hydrocarbon gas liquids ), and … WebFlowmeters are devices that measure the amount of liquid, gas or vapor that passes through them. Some flowmeters measure flow as the amount of fluid passing through the flowmeter during a time period (such as 100 liters per minute). Other flowmeters measure the totalized amount of fluid that has passed through the flowmeter (such as 100 liters).
