French Designated Institute for
high pressure gas flow metering

EXPERTISE IN GAS FLOW MEASUREMENT AT THE SERVICE OF MANUFACTURERS AND INDUSTRY

Our National Vision

(under the aegis of the French National Test Laboratory):

 

Our vision, within the field of gas flow measurement, is

 

- to preserve and improve national calibrations 

- to reduce measurement uncertainties.

Laboratory associated with the LNE

CESAME-EXADEBIT IS THE NATIONAL REFERENCE LABORATORY FOR GAS FLOW MEASUREMENT - MEDIUM AND HIGH FLOWS   The LNE (French National Test Laboratory) has the responbility for monitoring French metrology. It represents France in the forums of the Metre Convention (the International Committee for Weights and Measures - CIPM in French) and in international and European forums, such as EURAMET....

National standards for gas flow measurement

This section presents the standards put into place by CESAME-EXADEBIT to ensure the traceability of gas flow under high pressure.   The special feature of the traceability chain ensured by CESAME-EXADEBIT is the use of critical flow Venturi nozzles. These nozzles, used by the laboratory since the beginning of the 1970s, allows us to generate and measure the reference flow on the...
