Water Level Sensor 0–10 m LoRaWAN – Milesight EM500-SWL 868 (Probe L010-4846W)

The Milesight EM500-SWL 868 (Probe L010-4846W) is a professional submersible water level sensor designed for precise measurement up to 10 meters. The stainless steel probe is immersed directly in water, delivering stable readings regardless of foam, wind or rainfall.

Based on a vented gauge pressure measurement principle, the device provides long-term stable level monitoring with ±0.5% FS accuracy and 0.01 m resolution. It is engineered for demanding infrastructure, industrial and environmental monitoring applications.

Integrated LoRaWAN® connectivity (EU868) enables secure long-range wireless communication with low power consumption. The sensor is ideal for remote installations where wired connectivity is not available.

Powered by a 19,000 mAh Li-SOCL2 battery, the unit can operate up to 10 years at a 10-minute reporting interval under EU868 conditions.

Configuration is available via NFC mobile app or USB Type-C connection to a PC. With IP67 protection for the transceiver and IP68 for the probe, the EM500-SWL is designed for harsh outdoor environments.

Typical applications:

Groundwater monitoring

Tank and cistern level monitoring

River and flood level monitoring

Stormwater management systems

Agricultural irrigation control

Industrial water management

This model is specifically configured for a 0–10 m measuring range.
