Milesight EM500-UDL | LoRaWAN Ultrasonic Distance & Level Sensor

The Milesight EM500-UDL is a carrier-grade LoRaWAN Ultrasonic Level Sensor engineered for versatile distance measurement without physical contact. By emitting ultrasonic waves and measuring the time of flight, the EM500-UDL accurately determines the level of liquids or the presence of solid objects. Housed in a rugged IP67-rated enclosure, it is purpose-built for outdoor applications where reliability and longevity are paramount, such as flood monitoring, tank level tracking, and waste management.

Non-Contact Intelligence & Reliability

Advanced Signal Processing Features integrated temperature compensation to ensure measurement accuracy remains consistent despite fluctuations in ambient weather conditions. Data Integrity & Retransmission Equipped with internal memory to store historical records, supporting data retransmission to prevent gaps in analytics during temporary LoRaWAN network outages.

Professional Usage Scenarios

• Flood & River Monitoring: Deploy on bridges or culverts to track rising water levels and provide early warnings for disaster prevention. • Smart Waste Management: Monitor the fill-level of waste containers or grain silos to optimize collection routes and supply chain logistics. • Liquid Tank Monitoring: Ideal for non-potable water, chemicals, or oils where non-contact sensing is required to maintain purity or sensor life.
