This paper illustrates the gas flow rate measurement techniques that can be introduced in futuredomestic applications. First, the role of the gasmeter in legal metrology is introduced. Then, the “intelligent” (or “smart”) gasmeter is analyzed, since it should be used in the near future. Such a meter is an improvement of the currentdomestic diaphragm gasmeter, also equipped with electronic components, so as to obtain a more flexible instrument and a more convenient measurement data processing (temperature compensation, remote reading, etc.). After that, static gasmeters are analyzed. Such meters have no moving parts. Of this category, only ultrasonic and fluidic oscillator meters are reviewed here. At present they are in an advanced phase of experimentation for custody transfer gas metering. Thanks to their design, which does not include any moving parts, these meters may represent in the future the best solution to measure the consumption of natural gas for domestic use. This paper discusses the operating principles and metrological characteristics of the static meters mentioned above, and provides some experimental results regarding domesticgas measurement. Finally, their possible evolution and application on the international scene are briefly outlined.

Abstract
This paper illustrates the gas flow rate measurement techniques that can be introduced in futuredomestic applications. First, the role of the gasmeter in legal metrology is introduced. Then, the “intelligent” (or “smart”) gasmeter is analyzed, since it should be used in the near future. Such a meter is an improvement of the currentdomestic diaphragm gasmeter, also equipped with electronic components, so as to obtain a more flexible instrument and a more convenient measurement data processing (temperature compensation, remote reading, etc.). After that, static gasmeters are analyzed. Such meters have no moving parts. Of this category, only ultrasonic and fluidic oscillator meters are reviewed here. At present they are in an advanced phase of experimentation for custody transfer gas metering. Thanks to their design, which does not include any moving parts, these meters may represent in the future the best solution to measure the consumption of natural gas for domestic use. This paper discusses the operating principles and metrological characteristics of the static meters mentioned above, and provides some experimental results regarding domesticgas measurement. Finally, their possible evolution and application on the international scene are briefly outlined.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
