Method for controlling cryogenic tanks, corresponding cryogenic tanks and corresponding submarines

摘要

The present invention relates to a cryogenic tank (38) comprising a chamber (40) containing a liquefied gas, in which the liquefied gas forms a liquid phase (44) and a gaseous phase (46). This method is - measuring a parameter representative of the pressure of the gas phase (46) and a parameter representative of the pressure of the liquid phase (44); - measuring a parameter representative of the temperature of the liquid phase (44); and - determining the total mass of the liquid phase 44 from parameters representative of the temperature of the liquid phase 44 , the pressure of the liquid phase 44 and the pressure of the gas phase 46 . The present invention also includes corresponding cryogenic tanks 38 and submarines.
