12V lithium battery packs - ultrasonic flowmeter lithium battery pack applications
一、To ultrasonic flowmeter
Ultrasonic flow meter tube struts primers based on the principles of speed difference method, measurement of liquid flow in a circular tube instrument. It uses state-of-the-art multi-pulse technology, digital signal processing and error correction technology, the flow meter can adapt to the environment of the industrial field, measured at more convenient, economic and accurate. Products reach the advanced level, can be widely used in petroleum, chemical, metallurgy, electric power, water supply and drainage areas.
二、Lithium battery pack requires ultrasonic flowmeterThe ultrasonic flowmeter operating current of approximately 1.5-2A, to work for 3 hours, and more than 500 times the cycle life requirements of Division I to the combination BAK batteries, the battery has a high energy than light quality, small volume,high cycle life, high safety, high voltage consistency advantages.

三、Power Solution
The portable integrated flue gas analyzer lithium battery protection function
1, the protective plate (PCM): rechargeable lithium battery pack protection circuit design, smart electricity due to the chemical properties of the lithium battery, overcharge, over discharge, short circuit, overcurrent protection function. In order to avoid any risk of combustion, explosion, etc..
2, protection IC (Protection IC): the main protection function chip design, the batteries overcharge, over-discharge, over-current, short circuit and functional online constantly monitor the batteries in a safe, stable and efficient range.
3, the temperature switch: mainly designed for temperature protection function. When the battery itself, the temperature reaches the range of 70 ± 5 ℃ result of other anomalies, the temperature switching operation temperature protection
4,18650 lithium-ion batteries / 18650/2500mAh/3.7V Li-ion cell.
5, FETs (MOSFETs): MOSFET tube, to switch from the role in the protection circuit, always so that the voltage across the load will not be increased nor decreased, to ensure the voltage stabilization.
