FIELD: storage of gases.
SUBSTANCE: device for supply of cryogenic liquid includes means of connection for movement of cryogenic liquid into tank (2) and extraction of gas leaving said tank, first flow meter (12, 42) for determining liquid mass, outputting from supply device, second flow meter (28, 48) for determining weight of extracted gas, and device for determining calorific value of transferred liquid, and device for determination of calorific capacity of extracted gas.
EFFECT: technical result is possibility of determining energy, preferably, enthalpy, fed into the filled tank during movement of the cryogenic liquid and the energy balance of the cryogenic liquid movement.
