UL106 – Ultrasonic Level Sensor for Harsh Environments

The UL106 Ultrasonic Level Sensor delivers continuous level measurement and object detection even in demanding conditions. It is ideal for irrigation systems, tank monitoring, and open channel applications.

Typical Applications:

  • Automated irrigation systems

  • Tank level monitoring in industry and agriculture

  • Open channel flow and watercourses

  • Outdoor environments exposed to dust, dirt, or changing weather

Description

The UL106 – Ultrasonic Level Sensor for Harsh Environments uses advanced ultrasonic technology to provide continuous level measurement and object detection in challenging conditions.

Through non-contact operation, it accurately determines the distance to liquids or objects, delivering real-time, high-precision data. This reduces wear, maintenance needs, and allows deployment across a wide range of industrial, agricultural, and environmental applications.

The UL106 is engineered to maintain stable performance in difficult environments, including turbulent surfaces, fluctuating temperatures, dust, and moisture.

This sensor provides a reliable, durable, and versatile solution for precise level control even in demanding applications.

FAQ

1. Where can the UL106 be used?
It is designed for harsh outdoor and industrial environments, such as irrigation systems, tanks, and open channels.

2. Does the UL106 only measure liquids?
No – besides liquids, it can also be used for object detection (e.g., solids or obstacles in tanks and channels).

3. Why is UL106 suitable for irrigation systems?
It continuously monitors water levels in reservoirs, tanks, and channels, enabling precise irrigation control.

4. Is the UL106 low-maintenance?
Yes – as a non-contact sensor, it avoids direct exposure to the medium, reducing wear and maintenance.

5. What sets UL106 apart from other models?
It uniquely combines continuous measurement and object detection while being engineered for rugged, real-world environments.
