    • A system (1) and a method for determining a residual volume of a container unit (2) is disclosed. The system (1) comprises a container unit (2) comprising at least a primary container (3), means for applying a pressure inside the primary container (3), a flow restrictor (14) fluidly connected between the primary container (3) and the exterior of the container unit (2), means (P1, P3) for measuring a rate of pressure change of a pressure of the container unit (2), and means for determining a residual volume of the container unit (2) based on a measured rate of pressure change. The pressure inside the primary container (3) is allowed to adapt to the pressure of the exterior position in a controlled manner via the flow restrictor (14). Knowing the initial pressure in the primary container (3), and the flow resistance of the flow restrictor (14) the rate of pressure change is defined by the volume of the primary container (3), and this volume can thereby be determined. The volume of the primary container (3) thus determined may be the residual volume. Alternatively, the volume of the primary container (3) may be used for deriving another residual volume of the container unit (2).
    • 公开了一种用于确定容器单元(2)的剩余容积的系统(1)和方法。 系统(1)包括容器单元(2),该容器单元至少包括主容器(3),用于在主容器(3)内施加压力的装置,流体连接在主容器(3)之间的流量限制器 和容器单元(2)的外部,用于测量容器单元(2)的压力变化率的装置(P1,P3)和用于确定容器单元(2)的剩余容积的装置 测量压力变化率。 允许主容器(3)内的压力通过限流器(14)以受控的方式适应外部位置的压力。 了解初级容器(3)中的初始压力和流量限制器(14)的流动阻力,压力变化率由初级容器(3)的体积确定,从而可以确定该体积。 如此确定的主容器(3)的体积可以是剩余体积。 或者,主容器(3)的体积可以用于导出容器单元(2)的另一剩余容积。
