Ultrasonic Level & Distance Sensor EM500-UDL C050 – Milesight (LoRaWAN)

The Milesight EM500-UDL C050 measures level and distance using non-contact ultrasonic sensing. That matters in the real world: many sites don’t want anything touching the liquid or material—because it’s corrosive, dirty, hard to access, or simply maintenance-heavy. Mounted above the target, the sensor reads the distance to the surface and reports it over LoRaWAN (EU868), keeping installation clean and scalable when measurement points are spread out.

With a 0.25 to 5 m measurement range, the C050 variant fits many everyday monitoring jobs across industry, utilities, and outdoor infrastructure. Setup is straightforward via NFC using a mobile app, or via USB Type-C for configuration and console access, with downlink configuration supported as well.

Realistic deployment examples buyers actually implement:

Chemical and process tanks: monitor fill level without putting a probe into aggressive liquids or vapors.

Diesel / AdBlue tanks at construction sites or generator stations: track consumption and plan refills before a site runs empty.

Water and wastewater assets: level monitoring in pits or tanks, with alarms when levels change unexpectedly.

Bulk materials (pellets, granules, powders): inventory monitoring in bins/hoppers to reduce manual checks and prevent stockouts.

Municipal depots (e.g., salt storage): trend inventory and optimize delivery schedules.

Outdoor monitoring points: IP67 + UV resistance supports long-term exposure to weather and dust.

Operationally, the sensor supports features that reduce missed events: threshold alarms, change alarms, and on-device data storage with retransmission and retrieval options.
