TÜV SÜD joins research programme to improve meter accuracy

As part of the European Metrology Programme for Innovation and Research (EMPIR), TÜV SÜD National Engineering Laboratory has joined a research consortium which aims to improve the accuracy and durability of commercially available meters for renewable gases (biogas, biomethane, hydrogen, syngas).

Operators across the gas supply chain all require accurate measurements to bill transactions. However, renewable gases have different physical characteristics from more widely used natural gas, and research is required to determine the impact that these gases have on commercially available flow meters. The objective of this project is to provide reliable data to the industry and to make measurement recommendations for renewable gases, including any necessary adaptations to current gas meter standards.

TÜV SÜD National Engineering Laboratory is the UK’s national designated institute, responsible for flow and density measurement standards. Its research will deliver recommendations for the renewable gas conformity requirements of currently available gas meters, against the European Union’s Measuring Instruments Directive. While the directive seeks to harmonise many aspects of legal metrology across member states, it only covers natural gas applications and does not currently include any specifications for renewable gases.

Marc MacDonald, Project Engineer at the TÜV SÜD, said, “The development of renewable energy sources is encouraged by the European Renewable Energy Directives, but their effect on the measurement accuracy of natural gas flowmeters is still unknown. The impact is expected to be significant, so this project will evaluate how meter calibrations in the future will ensure the reliability of finance and fiscal transactions for renewable gases. Ultimately, this will support an ongoing improvement in both existing meter designs and flow calibration standards.”
