Abstract
A measuring device includes a first body, a second body slidably combined with the first body, a first pressure sensing component, and a control unit. The first body is for supporting a cup receiving liquid. The first pressure sensing component is disposed between the first body and the second body for sensing weight of the cup and the liquid and generating a signal corresponding to the weight. The control unit is electrically connected to the first pressure sensing component. The control unit determines a volume variation of the liquid according to a weight variation of the cup and the liquid calculated based on a difference between signals transmitted from the first pressure sensing component at different time points.
