Intelligent noncontact liquid level sensor Key benefits — why you need this sensor Enables safe, accurate liquid level monitoring for sealed, pressure or hazardous containers without opening them, reducing exposure risk and production interruptions. Overcomes measurement errors caused by varying container wall thickness, delivering reliable level readings across different nonmetallic walls. Simple external installation minimizes downtime and avoids contact with corrosive, toxic, or pressure liquids. How it solves common problems Noncontact sensing: probes mount outside the container at the and low level positions, so no penetration of the vessel or exposure to the liquid is required. Advanced signal processing: a speed signal processing chip and refined signal algorithms compensate for container wall thickness and material differences, ensuring accurate detection. Safe for hazardous fluids: suited for toxic substances, strong acids and alkalis, and other aggressive liquids contained in closed or pressurized systems. Key features and performance Function: noncontact liquid level detection using externally mounted probes at preset and low positions. Compatibility: designed for nonmetallic containers and piping; works on sealed and pressure closed vessels. Liquid requirements: the liquid to be tested must be electrically conductive. Contact surface requirement: the container wall (contact surface) must be nonmetallic. Installation: probes are mounted above and below the outer wall at the desired level points; installation is simple and does not affect production. Material and durability: suitable for detecting corrosive and hazardous liquids because the sensor does not contact the fluid. Signal and accuracy: speed signal processing chip and advanced filtering deliver stable, accurate readings despite variable wall thickness. Practical applications / use scenarios Chemical storage tanks: continuous level monitoring of strong acids or alkalis in sealed, pressurized storage tanks where leak risk or contamination prevents opening the vessel. Hazardousmaterial drums and process vessels: noncontact detection for toxic or corrosive liquids in industrial drums and closed reactors, allowing safe automation of filling and discharge processes. Electroplating or electrolyte systems: level control in nonmetallic piping and tanks containing electrically conductive solutions used in plating, etching, or battery manufacturing. Installation and operational notes Mount probes externally at the planned and low level positions on the nonmetallic container wall; no modification of the vessel interior is required. Ensure the measured liquid is electrically conductive for correct operation. Do not use on metallicwalled containers; the sensor requires a nonmetal contact surface. The probe and piping installation is straightforward and suitable for retrofitting existing systems. What makes this product stand out True noncontact measurement for sealed and pressure vessels, eliminating direct exposure to hazardous liquids. Robust signal processing that compensates for wall thickness and provides accurate detection where simpler sensors fail. Broad suitability across toxic, corrosive and conductive liquid applications without requiring vessel modification. For safe, accurate level control of conductive liquids in sealed nonmetal containers, this intelligent noncontact liquid level sensor provides a practical, lowimpact solution that prioritizes operator safety and uninterrupted production.
