Report on the Effect of the renewable gases on the uncertainty budgets of gas meters
This report the effect on the uncertainty budget of a gas meter when using renewable gases
Report on gas tightness testing of domestic gas meters for hydrogen applications
The tightness of a meter is required in order to obtain correct results in case of accuracy tests, but also for an application in the grid or for durability tests, to avoid risks such as explosive gas mixtures. In this report a reliable gas tightness test was developed.
Technical report on criteria and proposals for EMC tests on Ultrasonic meters with Non-Conventional Gases
This technical report is describing some proposals to test static gas meters when EMC testing due to some concerns which have been raised in the project
Report of Bench marking flow standards for use in testing the accuracy of flow meters with renewable gases.
This report is describing a literature study of the technologies usable for calibrating gas meters with renewable gases. It is also preparing a list consisting of the currently available flow standards which might be suitable for use with hydrogen, crude biogas, methane and mixtures of these gases. The report can be found in the link below.
Report of the Effect of hydrogen admixture on the accuracy of a rotary flow meter.
This report is describing the investigation of the effect on the performance of a high-pressure gas flow meter (rotary meter) when mixing hydrogen with natural gas. The rotary gas flow meter was calibrated using both natural gas and hydrogen enriched natural gas (nominally 15% hydrogen), at two different pressures: 9 and 16 bar. Results indicate that the differences in the meter errors between hydrogen enriched natural gas calibration and natural gas calibration at high-pressure are smaller than the corresponding differences between atmospheric pressure air calibration and high-pressure natural gas calibration.
