LNE-CETIAT

Centre Technique des Industries Aérauliques et Thermiques

The LNE-CETIAT is implementing the national references in hygrometry, in anemometry and in liquid (water) flow measurement and is developing the means to transfer the references to the industry.

LNE-ENSAM

Ecole National Supérieure d’Arts et Métiers - Paris

The Dynamic Metrology Laboratory, the LNE-ENSAM is in charge of the implementation and the improvement of the national references in dynamic pressure and of the development of means to transfer the references to the industry.

LNE-IRSN

Institut de Radioprotection et de Sûreté Nucléaire

The LNE-IRSN is responsible for the national references in the field of neutron dosimetry.

LNE-LADG

Laboratoire Associé de Débitmétrie Gazeuse

The LNE-LADG pools the resources of the Gaz de France (at Alfortville) and of the CESAME LNE Ouest (at Poitiers) flow measurement laboratories.
The LNE-LADG is responsible for the implementation and the improvement of the national references in
high pressure gas flow measurement and of the development of the means to transfer the references to the industry.

LNE-LTFB

Laboratoire Temps Fréquence de Besançon

In 2008, two laboratories (LNE-FEMTO-ST and LNE-OB) in Besançon merged in order to create LNE-LTFB (Laboratoire Temps Fréquence de Besançon). This laboratory, associated to LNE, includes the calibration activities witch are not cover by the LNE-SYRTE: frequency, time interval, short time (0,1 s to 100 s) and long time (more than 1 hour) stability, phase noise. These activities are accredited by the Cofrac. Moreover, LNE-LTFB also ensure the diffusion of national frequency standards by GPS link (for more information see the Cofrac Website: http://www.cofrac.fr).

LNE-TRAPIL

Trapil company

The metrology laboratory associated with the LNE is implementing the national references for liquid flow –other than water- measurement, primarily for the liquid hydrocarbons, and is developing means for transfer of these references to the industry.
