Milesight EM400-UDL | Industrial Cellular Level Sensor (NB-IoT)

The Milesight EM400-UDL (NB-IoT Version) is a carrier-grade Ultrasonic Distance and Level Sensor engineered for robust telemetry in remote locations. Utilizing high-frequency sound waves, it provides non-contact measurement for liquids and solids, eliminating sensor fouling. This NB-IoT model features integrated GNSS positioning for asset security and a 3-axis accelerometer to detect device tilt. Housed in a ruggedized IP67 enclosure with damp-proof coating, it is purpose-built to quantify levels in water reservoirs, chemical tanks, and silos across Europe and the Middle East.
