摘要： A method and apparatus for determining whether a fluid, such as a refrigerant, is a liquid or a gas. To determine whether the fluid at a predetermined level (14) of a storage container (20) is a liquid or a gas, fluid is withdrawn from the container at the predetermined level, depressurized under conditions that would cause it to become a gas if it is a liquid before such depressurization, then the temperature of the fluid after depressurization is measured and compared to a reference temperature that is or is related to the temperature of the fluid in the container. If the temperature of the fluid after depressurization and the reference temperature are approximately equal, one can conclude that the fluid withdrawn from the predetermined level is a gas. If the temperature of the fluid after depressurization is considerably lower than the reference temperature, one can conclude that the fluid withdrawn from the predetermined level is a liquid. Such a determination can be used, for example, in order to shut down an apparatus (3) for transferring a refrigerant into a receiving container when the liquid level in the container reaches a predetermined maximum level.

摘要翻译： 一种用于确定诸如制冷剂的流体是液体还是气体的方法和装置。 为了确定储存容器（20）的预定水平（14）处的流体是液体还是气体，流体以预定水平从容器中取出，在使其成为气体的条件下减压 是在这种减压之前的液体，然后测量减压后的流体的温度并将其与与容器中的流体的温度相关或相关的参考温度进行比较。 如果减压后的流体温度和基准温度近似相等，则可以断定从预定水平排出的流体是气体。 如果减压后的流体温度明显低于参考温度，则可以断定从预定水平排出的流体是液体。 这种确定可以用于例如当容器中的液面达到预定最大水平时关闭用于将制冷剂输送到容器中的装置（3）。
