Product Description
Technical Details
The Milesight EM400-UDL-N03GL (NB-IoT version) is a high-performance ultrasonic distance sensor designed for liquid level monitoring and distance measurement in both static and dynamic environments. It features various sensor probe options with measuring ranges from 30 to 500 cm (W050) or 50 to 1000 cm (W100), making it adaptable to different use cases.
Engineered for long-term deployment in harsh environments, the EM400-UDL includes a robust IP67 waterproof enclosure, damp-proof internal coating, and dual 9000 mAh replaceable batteries providing up to 10 years of operation.
This NB-IoT/Cat M1 model supports GNSS positioning for tracking and multiple IoT-friendly communication protocols, including TCP, UDP, MQTT, and AWS. Additionally, it features a built-in 3-axis accelerometer to detect tilt status, an NTC temperature sensor for burn detection, and NFC support for one-touch configuration.
Common applications include tank level monitoring, flood detection, and water level measurement in open reservoirs or sewer systems.
