Product Description Technical Details

The Milesight EM400-UDL PN:C100 Standard is a robust, non-contact ultrasonic distance sensor designed specifically for accurate liquid level measurement. With its long-range sensing capability of up to 1000 cm, it is ideal for a wide range of applications, including outdoor tanks, open water bodies, reservoirs, and utility monitoring.

This model operates using two 9000 mAh replaceable batteries, delivering up to 10 years of maintenance-free operation. It also includes an NTC temperature sensor for burn detection and a 3-axis accelerometer for monitoring tilt or abnormal position states.

The NB-IoT/Cat.M version integrates GNSS for real-time location tracking, supports multiple IoT communication protocols (TCP, UDP, MQTT, AWS), and offers cumulative reporting features to optimize energy consumption. Configuration is user-friendly via NFC and a mobile app.

With IP67 waterproofing, internal damp-proof coating, and rugged ABS+PC housing, the EM400-UDL is perfectly suited for harsh outdoor environments. It’s the ideal solution for smart city infrastructure, agriculture, and industrial tank monitoring.
