Metrology for reliable liquefied energy gases measurement

This project will determine the measurement reliability and uncertainty of (bio-)LNG flow meters in the field and develop traceable (bio-)LNG and LH2 meter diagnostics. It will determine the reliability of (bio-)LNG composition measurements under real world conditions and assess the achievable accuracy of LNG measurement equipment. The project will also determine the accuracy of in-field (bio-)LNG temperature measurements and develop traceable calibration procedures for systems measuring LH2 flow, composition, and temperature. It will create two flow standards for temperatures down to -253 °C and measurement uncertainty datasets for in-field measurements of (bio-)LNG composition and temperature. This work will improve uptake of (bio-)LNG and LH2, improving useability, transport and safety.
