Changes of liquid in a container can be timely by intelligent infusion monitor  which detects the weight of the container and capacitance of the electrodes. 
1. People can be reminded of timely disposal, and damage to patients due to the fact that no liquid injected to patients is avoided.
2. Alarm system for nursing center to monitor the infusion system.
3. Detecting the flow rate of the liquid.

This invention proposes a method to sense the fluid level in a container by detecting the changes of weight and capacitance of the container. This method can monitor an amount of fluid to be infused totaling less than the fluid within the fluid infusion bag.  An alarm is activated when either the no-fluid-flow condition, the near empty bag condition, or the preselected amount of fluid loss condition has been detected. 
Applications:
Infusion systems are widely used in medical treatments to supply and dispense fluids, such as sterile water, nutrients, medicines, saline, blood or blood products, etc. A conventional way to dispense an intravenous fluid is to suspend a supply of the fluid in a bag or bottle above the patient, connect the length of tubing to an outlet of the fluid supply, and deliver the fluid to the patient via the tubing through a needle inserted into the patient. By suspending the fluid supply above the patient, the fluid can be delivered to the patient at a desired pressure.
According this intelligent infusion monitor which detects the weight and capacitance, changes of liquid in a container can be detected timely. People can be reminded of timely disposal, and damage to patients due to the fact that no liquid injected to patients is avoided.
Features:
Changes of liquid in a container can be timely by intelligent infusion monitor  which detects the weight of the container and capacitance of the electrodes. 
1.People can be reminded of timely disposal, and damage to patients due to the fact that no liquid injected to patients is avoided.
2.Alarm system for nursing center to monitor the  infusion system.
3.Detecting the flow rate of the liquid
Future Applications:
When IoT becomes popular, the sensors or the needs for sensing become important.  This invention makes intelligent infusion system to IoT for simple and low cost.

當物聯網時代來臨，各種醫療照護的狀態希望能夠隨時傳達至需要資料的位置，如醫療照護中心，醫生或護士，關心的人員，因此如果測量裝置簡易，則可使成本降低並讓更多的資訊傳遞，本測量僅用電極片即可，因此簡易又方便。未來物聯網將可以大量使用。
