Milesight Ultrasonic Distance Sensor EM400-UDL-N03GL PN: C050 – Standard NB-IoT

The Milesight EM400-UDL-N03GL (Model C050) is a non-contact ultrasonic distance sensor specifically developed for accurate liquid level monitoring in tanks and open water environments. Engineered for outdoor use, it features a rugged IP67 waterproof enclosure and internal moisture-proof coating, making it ideal for harsh conditions.

This sensor supports NB-IoT (Cat.M) connectivity and integrates GNSS for precise geolocation, making it suitable for mobile assets and geographically distributed deployments. It comes equipped with dual 9000 mAh replaceable batteries, providing a lifespan of up to 10 years under TCP/UDP protocols.

The EM400-UDL provides enhanced accuracy of up to *±(1 + 0.3%S) cm within a range of 25 to 500 cm, and includes a 3-axis accelerometer for device tilt detection as well as an NTC temperature sensor for thermal anomaly alerts. Configuration is simple via NFC using a mobile app.

This sensor is ideally suited for applications such as tank level monitoring, flood detection, irrigation systems, and other industrial IoT uses where reliability and low power consumption are essential.
