VSL develops a portable calibration system for ammonia
Dit systeem, genaamd TRACTOR (TRaceable Ammonia CalibraTOR), kan dynamisch ammoniak in de lucht genereren in sporenconcentraties, zowel onder droge als vochtige omstandigheden.
VSL to start new series of LNG calibrations with fresh LNG batch from 1 April 2026
From that date, LNG terminals, shipping companies, engineering firms and suppliers of measuring equipment can once again have their flow meters calibrated with traceable measurements.
Metrology for Ammonia as an Energy Carrier
Given its higher volumetric energy density compared to hydrogen, ammonia is expected to play a significant role in long-term energy storage. To ensure a safe and fair rollout of ammonia as an energy carrier, it is essential to establish infrastructure for measuring quantity, quality, and emissions.
Metrology for Hydrogen Vehicles 3
This project focuses on developing faster methods for hydrogen flow calibrations (using master meters), combining flow calibrations with sampling for quality measurements, creating test protocols for gas composition sensors, and investigating potential new impurities.
VSL Achieves Accreditation for LED Light Flicker Measurements under European Ecodesign Directives
VSL Achieves Accreditation for LED Light Flicker Measurements under European Ecodesign Directives. The National Metrology Institute is now among the first institutes worldwide capable of calibrating and validating light sources against European ecodesign requirements for flicker.
Calibrating Flowmeters: How, When, and Why
Erik Smits, Manager Liquid Flow Metrology when VSL, the Netherlands National Metrology Institute, discusses the factors to consider when calibrating flow meters in systems.
