Designed for precise, non-contact liquid and solid level monitoring, the EM410‑RDL leverages 60 GHz millimeter-wave radar to deliver highly accurate measurements (±2 mm) over ranges from 0.3 m to 12 m in harsh environments. Its 8° narrow beam focuses on the target while filtering out interference from dust, condensate, and acoustic noise.
Built with a rugged PVDF enclosure rated IP68, it’s resistant to water (up to 1 m/48 hr), corrosion, and wear. Configuration is simple via NFC + Bluetooth, and it includes a 3-axis accelerometer for tilt alerts.
Available in LoRaWAN® and Cellular versions, the LoRaWAN variant supports OTAA/ABP, multiple regional bands, and seamlessly integrates with Milesight IoT Cloud and standard network servers.
Powered by a large 19,000 mAh ER34615 battery, it lasts up to 7 years on LoRaWAN mode.
Ideal for sewers, tanks, reservoirs, rivers, industrial tanks, and smart agriculture, offering reliable remote level sensing in remote or challenging locations.
