Measuring device for measuring a volume variation of liquid

A measuring device adapted for measuring a volume variation of liquid, the measuring device comprising:

• a first body being a cup sleeve having an accommodating space therein, the first body being configured to hold a lateral peripheral side of a cup receiving the liquid when the cup is accommodated in the accommodating space;
• at least one second body slidably combined with the first body at a lateral position adjacent to the lateral peripheral side of the cup and having a holding portion configured to be held;
• at least one first pressure sensing component disposed between the first body and the at least one second body to sense a pressing force of the first body applied on the at least one second body at the lateral position when the measuring device is lifted up to accordingly determine weight of the cup and the liquid so as to generate a signal corresponding to the weight;
• and
• a control unit electrically connected to the at least one first pressure sensing component and determining 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 at least one first pressure sensing component at different time points.
