? 應用鄰域 / Application
1. 水塔水位監測 / Water tower water level monitoring
2. 液位控制設備 / Liquid level control equipment 
 
3. 漏液保護設備 /Leakage protection equipment 
 
4. 缺液保護設備 / Lack of liquid protection equipment 
 
5. 帶水箱的產品 / Products with water tank 
 
6. 熱水器/ Water heater 
熱水器中沒有液體，則做停止加熱處理 
If there is no liquid in the water heater, do stop heating treatment 
 
7. 水族設備 / Aquarium equipment 
可配合遠程設備或者其他設備，實時監測魚缸里面的液位是否正常，例如在低水位監測點安裝傳感器，若水位到達此點則提示，或在高液位監測點，水位超過則提示，以確保魚缸水位不會過低過高。 
It can work with remote devices or other devices to monitor whether the water level in the aquarium is normal in real time. For example, a sensor is installed at the low water level monitoring point to prompt if the water level reaches this point, or at the high water level monitoring point to prompt if the water level exceeds this point, so as to ensure that the water level of the aquarium is not too low or too high. 
 
8. 適用于環境嚴苛的設備，高溫/高壓環境下監測水位 
It is suitable for equipment with harsh environment, and monitors water level in high-temperature/high-pressure environment
