LNG
Liquefied Natural Gas (LNG) is increasingly important in the energy transition as a cleaner alternative to diesel and bunker oil. Reliable and traceable measurement is essential for safe and efficient LNG use. VSL, the National Metrology Institute of the Netherlands, offers globally recognized solutions for LNG measurement, calibration, and testing.
VSL has a state-of-the-art liquefied natural gas calibration and test facility, the first in the world to actually test with LNG. The measurement standard that applies to this facility has greatly improved the precision and accuracy of LNG measurements. VSL’s responsible use of LNG is therefore a contribution to a sustainable society.

LNG calibrations
VSL operates the world’s first LNG calibration and test facility, where flow meters are calibrated under true cryogenic conditions (-162°C) using LNG as the calibration fluid. This ensures that LNG flow meters perform accurately in real-world applications. Calibrations are performed according to international standards, with low measurement uncertainty (CMC) and full traceability to the national standard. VSL can calibrate various types of flow meters, including Coriolis, ultrasonic, turbine, and delta P, provided they are suitable for cryogenic use.
Proficiency testing
VSL offers protocols and artefacts for the organisation and execution of proficiency testing (according to the EN ISO/IEC 17043:2010). We can arrange a round for groups of participants, such as a team of employees or a group of laboratories. Additionally, VSL provides proficiency testing on demand, allowing you to obtain results whenever you need them.
