Features 【Non-Contact Design】The Non-Contact liquid level sensor is suitable for the outer wall of non-metallic pipes that are not in direct contact with the liquid, and will not be corroded by corrosive liquids such as strong acids, and will not be affected by scale or other debris. 【Anti-Interference & Practicable】5-12V NPN liquid level sensor has high stability, high sensitivity, strong anti-interference ability, free from external electromagnetic interference, special treatment for power frequency interference and common mode interference, so as to be compatible with all 5-12V power. 【Accurate Measurement】The liquid level sensor is accurate and stable, and can detect boiling water level. The Level Error is less than ±1.5mm, could fits outer wall thickness less than 20mm. 【Stable and Durable】Electronic Liquid Level Sensor is very durable, pure electronic circuit structure, non-mechanical working mode, won't worry about the sensing mistake being larger and larger by mechanical abrasion, stable and durable performance. 【Intelligent Adjustment】Water level detector designed with intelligent liquid level reference adjustment, liquid level storage function, liquid level status display mode, can realize multi-point series connection.
