ABSTRACT:
In a freezing agent consumption measurement system for measuring the consumption of the freezing agent in a low-temperature container, due to evaporation of the freezing agent, including a gas flow meter provided in the gas flow path to measure the flow of the evaporated gas from the freezing agent, a tank is provided in the gas flow path means, and the pressure in the tank is maintained at a predetermined value. The measurement of the flow of the gas is not affected by the variation in the atmospheric pressure, and accordingly accurate measurement of the consumption of the freezing agent is accomplished.
