Compact noncontact liquid level sensor suitable for nonmetallic pipes and flat containers Key benefits — why you need this product Reliable, corrosionresistant sensing: designed for nonmetallic pipes (outer diameter D ≤ 11 mm) or flat containers where the sensing surface does not contact the liquid. Resistant to strong acids, alkalis and other corrosive liquids, and unaffected by scale or debris, reducing maintenance and replacement costs. Precise, stable level detection: accurate detection even at temperatures — capable of sensing boiling water level — so you can trust readings in demanding conditions. Flexible installation and networking: intelligent reference adjustment, liquid level memory, and status display make setup and monitoring simple. Supports multipoint series connection for monitoring several points with a single system. Long service life and low maintenance: pure electronic circuit, nonmechanical working mode delivers stable performance and extended lifetime compared with mechanical sensors. Main features (function, compatibility, size, material, performance) Compatibility: works with nonmetallic pipes where outer diameter D ≤ 11 mm, and with flatwalled containers when the sensor is not in direct contact with liquids. Corrosion resistance: sensing materials and design resist strong acids, alkalis and other corrosive liquids. Scale and debris immunity: performance is not affected by scaling or particulate contamination on the mounting surface. Intelligent functions: liquid level reference adjustment and memory function retain calibration and baseline settings for repeatable operation. Status feedback: liquid level status display mode provides clear indication of detected level conditions. Multipoint capability: supports series connection of multiple sensors for multipoint monitoring and centralized alarms or control. temperature detection: capable of detecting liquid at boiling temperature when installed per specification. Construction: pure electronic (nonmechanical) circuit design for stable operation and long life. Practical applications / use scenarios Chemical dosing and storage: monitor levels inside nonmetallic tubing or external flatsurface tanks where sensors must resist acids and alkalis without direct liquid contact. Food and beverage lines: detect liquid presence and boiling water level in nonmetallic process tubing, while avoiding contamination and mechanical wear. Industrial cooling and wash systems: add multipoint series sensors to pipe runs and flat tanks to monitor levels reliably despite scale buildup or corrosive cleaning agents. Installation notes Mount on nonmetallic pipe with outer diameter D ≤ 11 mm or on an external flat container wall; do not place sensor in direct contact with liquid. Use the intelligent reference adjustment and memory function during setup to establish reliable baseline detection. For multipoint monitoring, connect sensors in series according to system wiring instructions to achieve centralized level status reporting. This sensor is engineered for accurate, lowmaintenance liquid level monitoring where corrosion resistance, scale immunity, and longterm stability are required.
