THE MIKES MEASURING SYSTEM FOR GAS MASS FLOW |

- Abstract:
- Due to the increasing need for traceable gas flow measurements in Finland, the development of a national measurement standard for gas mass flow was initiated at the Centre for Metrology and Accreditation (MIKES) in 2002. A primary calibration system based on dynamic weighing was constructed to provide traceability directly to the national mass and time standards. The MIKES gas flow measuring system includes also a commercial calibrator based on laminar flow elements. It is used as a working standard when calibrating mass flow meters for customers. The calibration range encompasses 0,4 mg / s to 625 mg / s. The relative standard uncertainty of the gravimetric system is between 0,2 % and 0,4 %.
