The Milesight EM500-SWL is a rugged, submersible LoRaWAN liquid level sensor designed to measure liquid depth with high accuracy in harsh environments. Using long-range LoRaWAN communication, it transmits real-time level readings directly to your IoT server, enabling remote monitoring for water tanks, rivers, ISO tanks, wastewater systems, and oil storage in both urban and off-grid environments.
The stainless steel probe installs directly into the liquid, making it ideal for water resource management, industrial tank monitoring, and applications where reliable, continuous submersible measurement is required.
Built with vented gauge pressure measurement technology, it delivers high-accuracy readings (±0.5% FS) across three standard depth ranges. LoRaWAN long-range wireless ensures reliable transmission up to 10km line-of-sight at extremely low power consumption.
The device supports NFC and USB-C configuration, making installation straightforward and long-term maintenance effortless. Designed for up to 10 years of operation on a single built-in 19,000 mAh replaceable Li-SOCl2 battery – no solar or rechargeable variants required.
