Measuring device for measuring a volume variation of liquid received in a bottle
A measuring device for measuring a volume variation of liquid received in a bottle includes a bottle sleeve and a weight detecting module. A first accommodating space, a second accommodating space and a first opening are formed on the bottle sleeve. The first opening is communicated with the first accommodating space. The bottle sleeve is elastic. An inner diameter of at least one portion of the first accommodating space is less than an outer diameter of the bottle. The bottle sleeve holds the bottle when the bottle is inserted into the first accommodating space via the first opening. The weight detecting module is disposed inside the second accommodating space to measure weights of the bottle and the liquid at different time points and to determine the volume variation of the liquid according to a difference of the weights of the bottle and the liquid at different time points.
