The European Metrology Programme for Innovation and Research (EMPIR) coordinates research projects to address grand challenges, while supporting and developing the SI system of measurement units. There is an increased focus within EMPIR on innovation activities to target the needs of industry and accelerate the uptake of research outputs. The MetroPEMS project consortium encompasses 6 national metrology institutes (PTB, LNE, NPL, VTT, VSL and METAS) and 4 external partners (KIT, DTI, TU Darmstadt and Air Liquide).
The MetroPEMS project will develop new standards and calibration procedures for the three key components of a PEMS system: determination of NOx concentrations, number of particulates (PN) and exhaust mass flow. Based on these new measurements an improved PEMS instrument will be developed and validated along with traceable methods to extend performance for NO2 concentrations below 10 μmol/mol and up to 2500 μmol/mol. The work is expected to support the comparability of air quality measures across the EU and help manufacturers conform to current and future legislation.
