Description

The Milesight EM500-SWL is a high-performance LoRaWAN Submersible Liquid Level Sensor engineered for precision monitoring in challenging conditions. Utilizing a high-quality stainless steel pressure probe, the EM500-SWL measures the hydrostatic pressure of a liquid to determine its height with exceptional accuracy. By transmitting data over long-range LoRaWAN networks, it provides a reliable, wireless solution for tracking water resources, fuel tanks, or chemical containers without the need for manual dipping or complex wiring.

Industrial Precision & Longevity

Hydrostatic Pressure Sensing Features a corrosion-resistant stainless steel probe that stays submerged, providing a 0.01m resolution and high-term stability for years of accurate readings.

Extreme Deployment Life Powered by a built-in 19,000 mAh replaceable Li-SOCl2 battery, enabling up to a 10-year lifespan even in remote locations where power is unavailable.

Professional Usage Scenarios

• Water Resource Management: Monitor river, lake, and groundwater levels for flood prevention and environmental tracking.

• Industrial Tank Monitoring: Remotely track liquid inventory in oil, chemical, or water storage tanks in real-time to optimize supply chains.

• Smart Agriculture: Maintain precise water levels in reservoirs and irrigation systems to ensure consistent supply for livestock and crops.
