Résumé

Beginning in the 1980s, Coriolis meters have gained generalized acceptance in liquid applications with a worldwide installed base of over 300 000 units. To meet the demands of cryogenic applications below 20 K, off-the-shelf Coriolis meters have been used, with minor design modifications and operational changes. The meters were originally calibrated on water and tested on liquid helium at 4.5 K, supercritical helium around 5 K and superfluid helium below 2 K. The meters maintain their intrinsic robustness and accuracy of better than 1% of the measured value; accuracy is independent of density and temperature.
