Scope

This system table is suitable for the verification of gas flow measuring instruments in pipelines. It specifies the metrological parameters of a complete set of basic measuring instruments for gas flow national reference (volume flow under standard conditions of 0.3~120 m3/h), the procedure for transferring gas flow values with the help of temperature, mass, time, pressure, length and other references and standards, as well as standard flow meters, and indicates their uncertainties and basic verification methods, etc.
Note: Since 2003, the original "Metrology Verification System" has been collectively referred to as the "Metrology Verification System Table".
