Milesight EM500-SWL is a high-precision LoRaWAN® submersible water level sensor designed for accurate liquid level monitoring in harsh and demanding environments. It is ideal for applications such as water tanks, wells, rivers, reservoirs, and industrial storage systems.
Equipped with a robust stainless-steel probe, the EM500-SWL measures water level based on pressure detection and delivers highly accurate readings even in challenging conditions. It supports a wide measurement range (customizable up to 200 meters), making it suitable for both shallow and deep-water applications.
Using LoRaWAN® wireless technology, the sensor enables long-range, low-power communication, allowing data to be transmitted to cloud platforms for real-time remote monitoring. It also supports local data storage and retransmission to ensure reliable data delivery even during temporary network loss.
