Comparison VSL - PTB Volume flow for Natural Gas under High Pressure

Project Description

The bilateral comparison will be performed according to the procedure of CCM.FF-KC5a.1, EURAMET.M.FF-K5.a and CCM.FF-KC5a.2. A similar protocol will be applied. The transfer standards are kept unchanged compared to CCM.FF-KC5a.2.

Final Report 2023-04-18

The bilateral comparison failed due to contamination of the transfer standards, specifically the Ultrasonic Meter (USM) being used. Anyway, the documentation of contamination impact might be a useful information for applicants of this technology in field.

The project has been concluded and the report can be downloaded here>>.
