The Milesight EM400-UDL-N03GL-C100 is a professional-grade non-contact ultrasonic distance sensor designed for liquid level and distance measurement in harsh outdoor environments. This NB-IoT/Cat M version features a detection range of 0.25 to 10 meters and is equipped with GNSS for precise tracking and security. Built with a rugged IP67-rated waterproof enclosure and internal conformal coating, it monitors device tilt via a 3-axis accelerometer and temperature through an NTC sensor. Powered by two 9000 mAh batteries, it offers a long service life of up to 10 years and supports easy configuration through NFC. It is an ideal solution for monitoring water levels in tanks, silos, or slow-flowing water bodies, as well as detecting object presence or snow levels.
