ADW High-Precision Through-Wall Liquid Level Sensor: Accurate Liquid Level Monitoring Without Drilling or Direct Contact
2026.05.30
ADW introduces its innovative ultrasonic through-wall liquid level sensor, designed to deliver highly accurate, non-contact liquid level measurement through metal and plastic enclosures. By eliminating the need for drilling, direct liquid contact, or container modification, this advanced sensing solution addresses longstanding challenges in liquid level monitoring and offers a safer, more reliable alternative for sealed and pressurized systems.
Feature Specifications
Through-Wall Capability | Measures through metal and plastic containers |
Measurement Range | 15–500 mm |
Accuracy | ±1 mm |
Communication Interface | UART |
Installation Method | External mounting, no drilling required |
Non-Invasive Installation Through Container Walls
Traditional liquid level sensors often require openings in tanks or reservoirs, creating potential leakage risks and compromising structural integrity.
The ADW through-wall liquid level sensor utilizes proprietary ultrasonic signal processing technology to accurately measure liquid levels from outside the container. The sensor can effectively penetrate stainless steel, aluminum, PP, PVC, ABS, and other common materials, enabling precise liquid level detection without direct contact with the medium.
Installation is simple: the sensor is attached externally to the side or bottom of the container, making it ideal for:
Sealed tanks and reservoirs
Pressurized vessels
Corrosive liquid storage systems
Purified water and sterile fluid applications
Millimeter-Level Accuracy and Reliable Performance
Within a measurement range of 15 mm to 500 mm, the sensor achieves an accuracy of ±1 mm.
Advanced onboard algorithms effectively compensate for:
Container wall reflections
Temperature variations
Environmental interference
This ensures stable and reliable performance even in demanding operating conditions.
Digital Output for Seamless Integration
The sensor supports UART communication and provides direct digital liquid level output without requiring additional signal-conditioning circuitry.
Real-time data can be easily integrated into:
Microcontroller-based systems
PLC platforms
IoT devices
Smart monitoring solutions
This significantly shortens development cycles and reduces system complexity.
Compact Design for Flexible Integration
Featuring a compact footprint, the sensor can be easily integrated into equipment housings or mounted externally on containers where installation space is limited.
Its flexible design makes it suitable for a wide range of applications requiring reliable liquid level monitoring.
